ELECTRICAL GENERAL
DESCRIPTION
The electrical system used on this machine is a 12 volt negative ground system. Warm or Cold Start - Both of these
systems have one twelve volt battery. All electrical service is controlled by a master disconnect switch located in a
recess in the operators seat front support panel. The electrical system is basically divided into four groups; starting and
charging, lighting, indicators and accessories. The starting and charging circuits consist of the battery, cranking motor,
magnetic switch, neutral safety switch, keyed starting switch, engine shutdown solenoid, engine shutdown switch,
cranking motor solenoid, neutral start switch, master disconnect switch and an alternator with integral voltage regulator.
The lighting circuit includes light switch, circuit breaker, front and rear lights, and instrument panel light. The indicator
group consists of voltmeter, hourmeter and switch, transmission filter warning light and switch, hydraulic oil pressure
filter warning light and switch, air filter warning light and switch, engine oil pressure gauge and sender, engine coolant
temperature gauge and sender, and transmission temperature gauge and sender. The accessory group includes ether
start switch and solenoid valve, back up alarm and switch, warning horn and switch, and a circuit breaker. Using a
desired electrical tester, perform the necessary test(s) as outlined in the instructions furnished with the tool.
