_ MBR 70
MULTIPLE BATTERY REGULATOR

INTRODUCTION
You have purchased the finest voltage protection/charging system available on the market
today. The Wired MBR 70 incorporates the latest technological advancements to exceed cur¬
rent measurement standards of performance, craftsmanship and reliability.
Your MBR 70 includes these built-in features:
■ Isolates batteries when ignition is off.
■ Mounts in front or rear of vehicle.
« Senses charge voltage of auxiliary batteries.
« Brings charge voltage up on the vehicle's battery, then begins
charging the auxiliary batteries.
■ Enables the stereo system to draw off all the batteries when engine is running.
* Can be installed without cutting into factory harnesses.
* Has LED's to inform of, POWER and CHARGE status.
Wired's MBR 70 takes a totally new approach to ensure proper voltage levels in multiple
battery systems. The MBR 70 is a "smart" regulator/ isolator that senses the needs of the vehi¬
cle's battery and any additional batteries. Unlike conventional battery isolators, the MBR 70
requires no cutting into the factory electrical system. It allows all the batteries in your vehicle
to become a collective voltage source.
The MBR 70 ensures the proper voltage level in the vehicle's battery by concentrating solely
on that battery until it sees a charge voltage above 12.5 volts. Once this voltage level has been
established, the MBR 70 couples all the batteries so they can all be charged.
When your engine is running, the MBR 70 allows the alternator to feed the auxiliary batter¬
ies a regulated charge up to 70 amps.
When the ignition is turned off, the MBR 70 becomes a "one-way gate", isolating the cur¬
rent in the vehicle's battery from passing through to the auxiliary batteries. This "one-way
gate" ensures that the vehicle's battery will always have enough charge to start the car,
regardless of the charge level in the auxiliary batteries.

General Precautions
Before installation, make sure you select a dry location that will provide adequate ventilation
around the MBR 70. The heatsink has fins to couple generated heat to the surrounding air space via
thermal conduction. We recommend that you mount the MBR 70 flat on the floor of the trunk or
under the hood, in a location that will protect it from water damage. Remember, heat travels up
away from the heatsink fins.
improper wiring connections can seriously damage the MBR 70 and your vehicle. Be sure to care¬
fully follow the connection instructions in this manual. NOTE: If you are not sure of the connections,
contact your dealer.
When making power connections, make sure that each connection is clean and properly secured.
Failure to do so may result in damage to the MBR 70 and your vehicle. In addition, please observe
these precautions.
■ Mount the MBR 70 in a dry location,
■ Do not mount the MBR 70 on a plastic surface or other low combustion
point material,
» Do not place a glass or metal cover over the MBR 70 unless you have a cooling fan
at one end. Direct cool air along the length of the fins, rather than across them.
» Do not use more than 2 auxiliary batteries per MBR 70.

WIRING 8k MOUNTING
t. Select mounting location of the auxiliary batteries and the MBR 70. Make sure you
observe the General Precautions listed on the previous page.
2. Use a multi-meter or test light to locate the ignition wire at the fuse box. Be sure
that it reads 12 volts positive <+) when the engine is running and 0 volts
when the ignition switch is off (not on accessory). Mark this wire with a piece of
electrical tape.
3. With the ignition off, disconnect the negative {-) lead and positive (+) lead from
die vehicle's battery.
4. Install auxiliary batteryfs) with manufacturer's approved hardware.
5. Mount a 100 amp circuit breaker within 18 inches of the vehicle's battery.
WARNING: Failure to install a circuit breaker at this location could result in
severe damage to the MBR 70 and your vehicle.
6. Route a 4 gauge power wire from the fuse holder to the proposed location of the
MBR 70. At convenient points, fasten the power wire to the vehicle's body with tie
wraps. Use this technique to keep the wire from dangling across engine compo¬
nents. Use rubber grommets where power wire penetrates sheet metal.
CAUTION: Do not connect the power wire to the battery terminal at this time.
7. Position the MBR 70 and use either a felt-tip pen or center punch to mark locations
for the mounting holes. Drill a small pilot hole at each marked location.
CAUTION: Do not drill into the fuel tank, fuel lines, brake lines (under chassis),
or through any electrical wiring.
8. Mount a 100 amp circuit breaker within 18 inches of the auxiliary battery(s).
WARNING: Failure to install a circuit breaker at this location could result in
severe damage to the MBR 70 and your vehicle.
9. Remove the plastic plug on bottom of the MBR 70, insert the 4 gauge power wire
coming from the circuit breaker mounted in step 5, into the lug marked IN, then
insert a 4 gauge power wire coming from the circuit breaker mounted in step 8,
into the lug marked OUT.
10. Be sure to check both lugs to make sure you have made a solid and tight
connection with the set screws. Snap plastic plug back into the access hole, then
mount the MBR 70 securely in the desired location with four self-tapping screws.
CAUTION: Do not drill into the fuel tank, fuel lines, brake lines, (under chas¬
sis) or through any electrical wiring.
11. L ocate a metal chassis component that is within the reach of the MBR 7Q's
attached ground (black) wire. Cut away any carpet and scrape off the body
paint to expose bare metal. Be sure to clean the area with sandpaper until
you see a bright, shiny finish.

12. Drill a small pilot hole {'/«“ diam.) in the selected area and use a No. 10 self-tapping
screw to securely attach the crimped lug {on the end of the ground wire) to the
metal chassis.
CAUTION: Do not drill into the fuel tank, fuel lines, brake lines, (under chassis) or
through any electrical wiring.
13. After the ground has been properly attached, cover the exposed bare metal with paint
or grease to prevent rust.
14. Route the red wire from the MBR 70 along the vehicle's interior wiring channels until it
reaches the ignition wire you previously marked with tape in step 2. Make the appro¬
priate connections and watch for any sharp edges on passage holes. Use rubber grom¬
mets where ignition wire penetrates sheet metal.
15. Locate a metal chassis component that is within 18 inches of the auxiliary battery(s). Be
sure to dean the area with sandpaper to expose bare metal. Drill a Vs* hole in the
selected area.
CAUTION: Do not drill into the fuel tank, fuel lines, brake lines, (under chassis) or
through any electrical wiring.
16. Use a battery terminal and ring terminals to add a 4 gauge ground wire from the
auxiliary battery's negative {-) post to the chassis. Securely attach the wire using a Vs" lug
connector, bolt, nut and flat washers.
17. Connect the 4 gauge power wire coming from the OUT lug on the MBR 70 .
to the 100 amp circuit breaker mounted in stepS.
18. Connect the 100 amp circuit breaker to the auxiliary battery(s) positive (+}
terminal with a 4 gauge power wire. VI
19. Use a battery terminal and ring terminals to add an additional 4 gauge ground ^
wire from the vehicle's negative (-) battery post to the chassis. Securely attach the
wire using a Vs" lug connector, bolt, nut and flat washers.
20. Check all wiring and mounting to verify proper installation, and make
sure the vehicle's ignition switch is OFF.
21. Use a battery terminal and ring terminals to connect the vehicle's positive
{+) battery lead to the circuit breaker mounted in step 5.
22. Start engine, and check the status LED's on MBR 70. The MBR 70 should be on and
should show charging status within a couple of minutes. Note: If the vehicle's battery is
low, auxiliary battery charging will not start until vehicle's battery has a charge voltage
of 12. S volts.
