∆ CAUTION
• Before connecting battery cables, make sure no electrical components touch the front body trim or
other parts of the vehicle frame. Place a dry towel between the body trim and the center dash to
prevent an electrical short circuit.
5. Connect the battery, positive cable first.
6. Pull the light switch to the ON position The reading should be 11-12 volts. If the there is no voltage
reading, check continuity of the 16 gauge black wire from the headlight to the headlight diode. Check
continuity of the 16 gauge black wire from headlight diode to the vehicle frame. If the wires show conti-
nuity and the readings are still incorrect, replace the headlight diode. See Headlight Diode Removal,
Section 12, Page 12-30.
7. With the Forward/Reverse handle in the NEUTRAL position and the wheels chocked, start the engine
