Installation (continued)
B. HONDA GAS ENGINE ONLY: If engine is connected to the vehicle battery:
1) The vehicle battery should have a minimum capacity of 24 AH and at least 350 CCA rating.
2) The wire size must be a minimum of #4 AWG. If the positive cable is longer than 5 feet or the
Negative cable is longer than 7.5 feet the wire size should be increased so that the maximum
voltage drop from the battery to the unit connection does not exceed 0.5 volts while cranking.
The battery location should be selected to keep the connecting leads as short as practical.
3) The Honda engine's charging system should be disabled to prevent the damage from the
vehicles charging system. This is done by removing the rectifier diode that is located in the
key switch box.
a) Remove the Phillips head screw holding the black plastic cover on the back of the key
switch box See Figure 3.
