TROUBLESHOOTING PROCEDURES
WARNING
Certain precautions must be observed before beginning any tests on the 24-V system.
Do not permit a hot wire to touch metal parts of the vehicle at any time. Flash testing by
striking a hot wire against a vehicle ground will cause an arc that will completely destroy
the connector on the lead. Accidental contact of metal tools between battery or starter
cables and frame of vehicle causes a direct circuit resulting in arcing of tools. This can
cause serious damage to tools, vehicle components, and batteries. Overloaded
batteries may explode, spraying hot acid and sharp fragments over surrounding area.
The correct procedure when removing electrical equipment, harnesses, battery cables,
or starting cables is to turn off the MASTER switch and disconnect battery ground cable.
Protect ground cable from accidental contact with battery terminal. When work has been
completed, connect battery ground cable last.
See Hull Wiring Diagram (see fold-out illustration at back of this manual) for complete wiring of the entire vehicle.
NOTE
While performing electrical troubleshooting, the black lead of multimeter must have
metal to metal contact with ground point to receive accurate reading.
