Electrical Test - Model 200
With the unit completely connected, start the vehicle and run at idle. Turn the Unit switch on
the control box to the "ON" position. With a DC multimeter check the voltage across the battery
terminals of the unit. You should read 12.7 + volts on the meter. If available, check the current draw
with a clamp-on ammeter capable of reading AC/DC true RMS such as a Wavetek AD105 Cat.III
1000 Amp. You should obtain a reading of 80-85 Amps.
Electrical Test - Model 250
The test of the Model 250 is slightly different from the 12 volt model. Once all the cables have
been installed, connect the control box at the 7 pin cannon plug. Unplug the blower from the
inverter. Turn the unit swith on the control box to the "ON" position. You should hear the contactor
energize. Now turn the inverter on at the switch provide on the front panel. A green indicator light
should come on and you will hear a slight whistle as the internal capacitors of the inverter charge.
