ML II 8KW (Cat1.1,CSA, 1250 W) alternator will not charge battery:
**Make sure battery is good and in working condition before testing**
❏To test the output of the alternator, place the positive lead of your volt meter on
the positive terminal of the battery, then place the black lead on any ground point
on the machine. You should read approximately 14 volts while the engine is
running.
❏(Note: All alternators are 12v) Alternators receive charge from the SLS panel
within the control box. Make sure to check the 15 amp fuse for the alternator
charging circuit.
❏If 15 amp fuse is good then check all wire connections in the harness and to
Alternator. Make sure all pins inside of harness plugs (pink & blue) are seated
and making contact. Check for oxidation on each pin.
❏If this is a Cat 1.1 early (2012-2017) then proceed to check voltage regulator.
Any amount of charge that is lower than 14+.05v is an indication that the voltage
regulator will have to be replaced.
❏If the problem persists then proceed to testing or replacing the alternator.
ML II CSA (CANADA SPEC) LSC 2.1 Powers off LSC screen when starting unit up.
❏Ensure all connections to each terminal are making contact and are secure.
Check all crimps and ensure insulation is clipped far enough back at the end of
the wire.
❏Check power at pin#6 into LSC and make sure the module is getting power.
❏If there is sufficient voltage and LSC still does not function then replace the entire
module.
Maxi Lite II Vert or LD series runs for 10-20 seconds:
❏If the unit runs for only 10-20 seconds then the issue could be either the Water
Temperature or Oil pressure switch.
❏Use a suitable multimeter to measure resistance of the coolant temp switch.
When the temperature of the coolant is 50 * c (122 F) or less, disconnect the wire
connector from the coolant temperature switch.
❏Place the lead of the multimeter on the connector of the coolant temperature
switch. Place the other lead of the multimeter on a ground for the coolant
temperature switch. **Measure the resistance. The resistance should be 54+ 2
ohms.**

MAXI LITE II
SERIAL NUMBER 10-000001 & 11-000001
❏Repeat the previous step when the temperature of the coolant is approximately
120 C (248 F). The resistance should not be less than 15 ohms,
Maxi Lite II Vert or LD series runs for 45-60 seconds before turning off:
❏Check power from generator to main breaker and if 120 volts are not present,
then check the capacitor. If the capacitor passes the test then the issue is in the
generator end internally. **See generator manufacturer manual for flashing tips.**
❏If power is coming from the generator to the main breaker, look for a small 16
gauge black wire connected to the back side of the main breaker. Black wire gets
120 from the main breaker to the orange wire and into the relay. Make sure
power is measured correctly.
❏Relay closes and green wire at the opposite end will send 12 volts to pin#4 of the
SLS to signify there is generator voltage. IF SLS does not receive power then the
unit will cut power to the fuel shut off solenoid hold wire.
❏Check 2 amp inline fuse on orange wire. Replace if failed
❏Check the relay and make sure it opens and closes. If failed replace it
❏Check for loose crimps, faulty connections or loose grounds.If there is a break in
the line then tighten or replace.

***Units with LSC modules (digital display screens/ Auto start) have a smaller
120 transformer that plugs into pin#16 of LSC. Check power from main breaker
all the way up to pin#16 for correct voltage.***
Lights fail to Illuminate.
❏Check power at the main breaker. Power should be 120/240 from the gen to the main
breaker. If power is lower than recommended rating, check the capacitor and generator
output.
❏If power is 120 at the main breaker, proceed to the light switched and light relays. Each
light breaker should have the same voltage at the main breaker (120/240) and current
should pass through each light relay. If voltage is found to drop then fix or replace the
breaker or the light relay.
❏Power is tested good at both light and switches, ensuring ballast is receiving sufficient
voltage in ( @ 120/240). Power out of ballast to the capacitor and light circuit should
measure 360-440 volts (+/ - 10%) is within spec.  **If a voltage test yields high voltage
other than normal at lamp output to light then this is an indication that the
light/tower cord has a short (Example- 500-600 volts indicates backfeeding
through tower cord due to short in circuit).
Testing generator output at the GFCI receptacle:
 WARNING: Dangerous voltage and/or current may be present when a
voltage test is being conducted. To reduce the risk of serious injury or death from
electrical shock, if you are not trained to safely work with high voltage, do not attempt
any of these procedures. You must seek assistance from qualified personnel.
Generator output voltage may be tested by using a multimeter to measure the voltage
across the terminals of the GFCI power receptacle.

MAXI LITE II
SERIAL NUMBER 10-000001 & 11-000001
Test the power output at the GFCI receptacle, while the engine is running and the main
breaker and receptacle breaker is switched to the “ON” position.
Set the multimeter to the AC volt position and insert the probe tips into the hot and
neutral sides of the GFCI receptacle.(See figure A below)
A meter reading of 120.0 volts +10% indicates that the generator is operating properly.
Refer to page 2. For further troubleshooting procedures.
A reading less than 120 volts + 10% indicates that the generator may be malfunctioning,
or there can be an issue with the main circuit breaker, pop out receptacle circuit
breaker, GFCI receptacle by itself, or the wiring between any of these. Refer to page 2
for additional troubleshooting.
NOTE: Many Allmand light towers designed for use outside North America operate at 230 volts/
50 Hz. Testing is done the same way following the above instructions. If you are unsure which
voltage your light tower is designed to produce contact a qualified electrician for assistance.

Testing Generator at Main Circuit Breaker:
WARNING: Dangerous voltage and/or current may be present when a
voltage test is being conducted. To reduce risk of serious injury or death from electrical
shock, if you are not trained to safely work with high voltage, do not attempt any of these
procedures. You must seek assistance from qualified personnel.
When testing the Generator output at the GFCI receptacle ( section A ) shows zero or
low voltage, or is inclusive, it will then be necessary to test the generator voltage at the
main circuit breaker. The main breaker may also be tested for proper function during
this procedure.
To access the main breaker, ( ensure the engine is off) remove the four screws holding
the control panel faceplate in place and carefully pull the faceplate away from the
control box. Allow the faceplate to hang from the attached wiring. Caution Do not allow
any of the terminals on the control panel faceplate contact the control panel box
or any other metal object.
Your multimeter scale must be set to AC volts. Start the engine and while the engine
has reached the correct operating speed (RPM) apply one probe from the multimeter to
the ground stud , and the other probe to one of the top (input) terminals on the main
breaker. Repeat the test for both terminals ( see figure L.1 and L.2). 120 volts+10%
must be measured at each terminal. If 120 volts +10% is not measured at each terminal,
either the generator,the generator capacitor or the wiring from the generator to the main
circuit breaker is faulty. Refer to the troubleshooting flowchart ( Section 1.6 forward) to
further isolate the problem.

WARNING: Dangerous voltage and/or current may be present when a
voltage test is being conducted. To reduce risk of serious injury or death from electrical
shock, if you are not trained to safely work with high voltage, do not attempt any of these
procedures. You must seek assistance from qualified personnel.
If the previous procedure indicates proper voltage at the top (Input) main breaker
terminals ( see figure M.1 and A.1 on the next page). The meter reading should indicate
120 volts +10%. If a reading of 120 volts +10% is not measured at each terminal, the
main breaker is faulty and must be replaced. See page 1 for a list of parts, visit our web

Testing Engine Speed at the GFCI Receptacle.
WARNING: Dangerous voltage and/or current may be present when a
voltage test is being conducted. To reduce risk of serious injury or death from electrical
shock, if you are not trained to safely work with high voltage, do not attempt any of these
procedures. You must seek assistance from qualified personnel.
The speed of the engine may be tested by using a multimeter with the scale set to read
hertz. NOTE: Not all multimeters have Hertz scale.
Set your multimeter to the Hertz ( Hz  ) scale. While the engine is running and the light
breakers turned off, insert your meter probes into the GFCI receptacle as shown in
figure N.1  ( Pg. 14). The meter should read 62.0 Hertz with no load on the engine. A
reading of less than 62.0 Hertz indicates that the engine is not running with enough
speed to create the necessary power to operate all of the lamps consistently.
Slow engine speed may be caused by a number of factors:
A. Incorrectly adjusted engine governor. Adjust governor as shown on the following
page ( Figure D.1/Pg 15 ) until a reading of 62.0 Hz  is indicated on the multimeter
display.
B. Clogged or dirty air and or/fuel filters. Replace filters if there are any questions as
to their condition.
C. Dirty fuel. Drain fuel tank and fuel system and replace with known clean fuel.
Replace fuel filter before re-starting the engine.
D. Worn or damaged engine. If the above steps fail to correct the engine speed this
may indicate a faulty engine. Contact your local servicing dealer for the make
and model diesel engine in your light tower. Repair, build or replace as
necessary.
Note: Many Allmand light towers designed for use outside of North America operate at
230 Volt + 10%s/ 50Hz. Engines on these models must be set for 52.0 Hz at no load per
the above instructions. If you are unsure which voltage your light tower is designed to
produce, contact a qualified electrician for assistance.

Testing Ballast & Generator Capacitors.
WARNING: Dangerous voltage and/or current may be present when a
voltage test is being conducted. To reduce risk of serious injury or death from electrical
shock, if you are not trained to safely work with high voltage, do not attempt any of these
procedures. You must seek assistance from qualified personnel.
Disconnect both capacitor leads
Using a screwdriver or similar instrument with an insulated handle, short the capacitor
between the terminals to discharge any stored power (Figure B.1). The capacitor may
be freely handled after it has been discharged.
Select Ohms  on your multimeter to  the highest setting.
Check the resistance between the capacitor terminals (Figure R.1).
A. If the meter shows a low resistance reading which gradually increases, the
capacitor is likely good and does not need to be replaced.
B. If the meter shows a very high resistance that remains steady, the capacitor is
open and must be replaced.
C. If the meter indicates a very low resistance that remains steady, the capacitor is
shorted and must be replaced.
