Hi Guys,
I have a PC10 Komatsu excavator. Recently, when I turn the key on before starting, a buzzing sound started coming out. When it buzzes, the engine won't start (gets no fire). When I turn the key and hear no buzz, the engine turns over maybe once before cranking. I traced the buzz to a part in the ignition system. Its is a small square part that plugs into a plug with 5 connectors on it. The info written on it is below:
Kokusan 12v Safety Relay SN 22029h Denki Japan.
When the thing "flakes out," if the machine is off, it won't start. If the machine is running, it won't shut off. The problem is, I can't find any reference to this part number anywhere.
Does anyone know where I might find a replacement, or a method to bypass this safety relay???
Thank you for the help!
