I have a 4108 running a generator
. Any brand gauge will work
gauges are the easiest to install. Amazon and Ebay will be the cheapest places with the most choices. Once you have your gauges, buy a hole saw to cut the holes. A standard ampmeter needs heavy wire to and from the engine
. A volt meter uses light wire and may give you enough info. Another option is a shunt ampmeter. The shunt is mounted near the engine
and connected with heavy wire and light wire goes between the shunt and gauge.
The gauges need 12 volts to operate and for lighting
. Usually the power to the gauges goes thru the ignition key. The light circuit often has a rheostat to dim the lights. If you don't have a wiring
diagram try looking online.
My 4108 uses a generic stop solenoid. It's mounted behind the injector pump
and connects to the stop lever with a piece of wire with bent ends. A button with 12 volts energizes it. The stop lever can be operated by a cable, too.
Tachs usually operate off the alternator
although some have a crank pickup. You may need hands on help with this. I don't have tachs on my generators and the mains have senders. I don't use stock alternators.
