Towed Vehicle

Battery Charger

STEP ONE: For safety's sake, disable your house battery charger and solar panels before disconnecting the battery cable from the Negative

post on the motorhome starting and house batteries. Next, identify a suitable point for connecting the kit's wire harness to the Positive and

Negative/Chassis Ground sides of your motorhome's starting or house batteries (either at your motorhome's battery isolator or directly to the

battery posts), but don't connect the wires yet. (NOTE: Connecting the harness to the motorhome's HOUSE batteries has the advantage of

allowing the towed vehicle to be recharged overnight when parked with AC hookups.) Route the harness rearward to your motorhome's

receiver hitch, using the Nylon Wire Ties (included in the kit) as the means of attachment every few feet or so. Take care to keep the harness

from touching hot exhaust parts, sharp edges or moving parts of the motorhome drivetrain. After you reach the hitch at the back of the motor

home, cut off any surplus wire, leaving about a foot of harness dangling beyond the hitch. Save the surplus wire for use in STEP TWO below.

GENERAL INFORMATION — TOAD-CHARGE™ keeps the battery in your towed vehicle (or "Toad") charged while it is being towed behind your motorhome, thereby

solving the battery discharge problems often caused by auxiliary braking systems or leaving the steering wheel unlocked while towing. The kit connects between your

motorhome's starting or house batteries and the towed vehicle's battery, using the motorhome's engine to supply up to 10 amps of current to the towed vehicle's battery.

The kit consists of several components: A Charge Controller installed in the towed (or "Dinghy") vehicle's engine compartment monitors the charging current, and

prevents reverse current flow when the motorhome engine is started. A 15 Amp Circuit Breaker installed near the motorhome starting battery protects against excessive

current flow due to wiring faults or a dead battery. The Charge Controller and Circuit Breaker are connected together by wire harnesses which are cut to desired lengths

from 40 or 60 feet of 12 gauge dual-conductor wire. Detachable connectors on the tow bar harness allow it to be stowed along with the tow bar when not needed. The

harnesses include a dedicated ground wire, thereby minimizing the voltage drop that might otherwise be present when relying on the motorhome's trailer hitch wiring.

STEP TWO: Mount the 15 Amp Circuit Breaker next to your chosen

motorhome battery connection point, using 2 sheet metal screws (included)

in 1/8" drilled holes (as shown below). WARNING: DO NOT OMIT THE

CIRCUIT BREAKER, OR A FIRE HAZARD WILL RESULT! On the end of

the harness, remove several feet of white plastic covering to expose the Red

and Black wires. Cut these wires just long enough to reach the Circuit

Breaker (for the Red wire) and Negative/Chassis Ground (for the Black wire).

Next, take the surplus cable left over from STEP ONE, split

the white plastic covering off it to expose the Red wire inside,

and cut this wire so that it is long enough to connect between

the 15 Amp Circuit Breaker and your previously-chosen

Positive connection point. Strip both ends of this wire,

crimping a small yellow ring terminal to one end before

attaching it to the BATTERY terminal on the Circuit Breaker.

Crimp either a small, medium or large yellow ring terminal to

the other wire end before attaching it to your chosen Positive

connection point.

Next, strip approx. 1/2" of insulation off this Red wire, and crimp a small yellow ring terminal to

it before connecting it to the HARNESS terminal on the circuit breaker. In a similar manner,

crimp a ring terminal (small, medium or large size) to the cable's Black wire before connecting it

to the Negative/Chassis Ground connection point you previously chose in STEP ONE above.

STEP FOUR: Inside your towed vehicle's engine compartment, identify points for connecting the Charge Controller to the vehicle's battery

terminal bolts, using a pair of small, medium or large-diameter yellow ring terminals. Use 2 sheet metal screws or Nylon Wire Ties to mount the

Charge Controller near your battery connection points (similar to circuit breaker mounting in STEP 2 above). For safety's sake, disconnect the

vehicle's battery cable from the Negative post on the battery before proceeding.

Next, take one end the surplus harness wire left over from STEP 2 above, strip 1/4" off its red and black wires before connecting them to the

MH terminals on the Charge Controller (Red wire to MH+ terminal, Black wire to MH– terminal). Secure the wires near the connector with another Nylon Wire Tie

(as in STEP 3 above). Route the other end of this harness from the charge Controller to the dinghy vehicle's front grille, using Nylon Wire Ties to secure it along

the way. After routing it to exit through the grille near a tow bar attachment point, cut off any surplus length, leaving about a foot of harness dangling next to the

tow bar. Finally, repeat the process described above in STEP 3 to attach a FEMALE (smaller) plug-in connector and MALE "dust cap" to it.

STEP THREE: On the motorhome hitch end of the harness, remove approx. 1" of the white plastic outer covering. Strip approx. 1/4" of

insulation off the exposed red and black wires, twisting any frayed small copper wires back together. Next, fully insert these bare wires into

one of the green FEMALE (smaller) connectors included in the kit before tightening the connector screws to captivate the wires. The Red wire

goes to the connector pin marked with a red stripe; the Black wire goes to the other, unmarked pin. Do not overtighten the connector

screws. Slip a black Nylon Wire Tie around the red and black wires next to the connector, tighten it snugly, and then snip off its excess end.

Finally, loop a piece of green plastic keeper cord through the black wire behind the connector, through a black plastic bead, and then connect

both ends of the cord to a MALE (larger) connector. This connector serves as a "dust cap" whenever the cable is not in use.

With the tow vehicle cable connected to the motorhome, the green POWER light is always illuminated to confirm that the Charge Controller is receiving DC power from

the Motor Home. The Yellow CHARGING light illuminates whenever the motor home is supplying sufficient voltage to charge the dinghy battery (13.2 volts or

greater).Typically, this occurs when the motor home engine is running. (NOTE: If the kit is connected to the motorhome's house batteries, the lights may also illuminate

whenever AC shore or generator power is present.)

When the motorhome engine is shut off (and, in installations where the kit is wired to receive power from the house batteries, shore power is also removed), all dinghy

charging will soon cease. As the motorhome battery voltage gradually drops, the CHARGING light on the Charge Controller will eventually turn off. Shortly after the

tow vehicle cable is unplugged, the green POWER light will shut off.

The Charge Controller draws no current from the dinghy's battery. There is no need to unplug the cable whenever the hitched motorhome/towed vehicle combination

are parked overnight, or to disconnect the Controller when driving the towed vehicle by itself.

The Charge Controller is designed to prevent reverse current flow back to the motor home. This feature is also used along with the 15 Amp Circuit Breaker to ensure

that a short circuit at any point along the wire harness will not allow excessive current to flow from either the motorhome or towed vehicle batteries – an important

safety benefit.

Periodic maintenance consists of: (1.) keeping the cable connectors free of dirt and road grease (a spray can of WD-40® works well for this task), (2.) inspection of the

harness wires for frayed or damaged insulation, and (3.) tightening any loose harness wire screws on the green plug-in connectors. When not in use, the motorhome

and towed vehicle green plug-in connectors should be mated to their protective dust caps.

Strip 1/4" from the opposite ends of Red and Black wires you previously connected to the Charge Controller, crimp them to

the appropriate sized yellow ring terminals (included), and then attach these terminals to the bolts on the battery cable

clamps (Red to Positive; Black to Negative). NOTE: If your dinghy vehicle battery isn't located in the engine compartment,

make these connections to the Positive and Negative terminals on your vehicle's Jump-Start terminals instead.

STEP SIX: With your tow bar attached and extended in the same manner as it would be when towing your dinghy vehicle, take the surplus

harness left over from STEP 5 above and use Nylon Wire Ties to attach it from one end of the tow bar to the other (i.e., from dinghy vehicle to

motor home). Cut off any excess harness, making sure to leave enough of it dangling at both ends to reach the connectors on the motor home

and dinghy vehicle under ALL driving and stowage conditions - In particular, leave enough slack to allow unrestricted movement as the tow

bar flexes up and down or folds against the tow vehicle (if applicable). If your tow bar folds sideways or telescopes, be sure to attach the

harness to it in such a manner that the harness isn't pinched when folded or retracted. Next, attach green MALE (large) plug-in connectors to

both ends of this harness, taking care to match the Red wires with their corresponding red stripes on the connectors. Secure these wires near

their connectors with another Nylon Wire Tie (same as shown in STEP 3 on the previous page).

STEP FIVE: Take the surplus harness left over from STEP 4 and cut a piece of it just long enough to

connect the Charge Controller to the dingy battery connection points you previously chose in STEP 4.

Remove the white protective sleeve, strip 1/4" of insulation off one end of the Red and Black wires inside

it, and connect these ends to the DINGHY terminals on the Charge Controller (Red wire to DINGHY+,

Black wire to DINGHY–). Secure these wires near the connector with another Nylon Wire Tie (same as

shown in STEP 3 on the previous page).

Finally, re-connect the motor home and dinghy

negative battery cables to their battery posts. This

completes the entire installation process.

Troubleshooting - In Case Of Problems*

SYMPTOM - The Green POWER light is not illuminated whenever the kit is plugged into the motorhome. Check for loose wire crimp connections on the ring terminals

at the motor home battery and 15 Amp Circuit Breaker, and for loose wire screws on Charge Controller, dinghy vehicle battery posts, and all green plug-in connectors

on the wire harness. On the Circuit Breaker, also check the brass nuts which attach the ring terminals to the Circuit Breaker for tightness.

SYMPTOM - The Yellow CHARGING light is not illuminated whenever the motor home engine is running. Check to see if motorhome starting and/or house batteries

are heavily discharged - Since first priority is given to recharging these batteries, the voltage produced by the motorhome engine may not be high enough to turn on the

Charge Controller until these other batteries have had a chance to accept some charge. Typically, this problem will remedy itself within a few minutes after the motor

home engine is started.

SYMPTOM - The Green POWER and Yellow CHARGING lights are alternately flashing rapidly. This indicates that the Charge Controller is not connected to the dinghy

vehicle battery. Check for loose connections on the Charge Controller and dinghy battery cable bolts.

SYMPTOM - The red REV POL light is glowing steadily. This indicates reverse polarity, and only occurs if the kit is wired incorrectly. Check for reversed wire
