Cat 304cr joystick wiring

[Ignaciojezriel45]

I have aftermarket thumb on my mini exc my thumb won’t go down most of the time. I’ve replaced the joystick and solenoids it worked for about two hours. I took switch apart and found carbon buildup on contact. I cleaned it and it works until it arks when making contact and carbon builds up again and stops working. I believe it’s wired incorrectly but can’t find a diagram of how it should be wired. Any help is appreciated

FYI all you need is the machine Serial Number to obtain parts & service information. "Year" means nothing.

I'll send you an electrical schematic. Keep an eye on your messages.

Not AFAIK. You would have to buy one. Search the interweb for Caterpillar Publication RENR6660. I can't see one at the moment. You can buy a new one from HERE in CD form for $420.
