CAT 304cr
Serial NAD00852
Looking for electrical schematic for glow plug relay and timer.

Unsuccessful at finding a pdf online to purchase.

currently glow plugs are wired to a push button and I want to get the factory configuration working, relay is good. Not sure what wires go where on the timer. Any help is appreciated.

I'll send you a PM with the schematic.
Kudos for posting the S/No BTW, most people don't. In your case it's important because there is a change at 1633, machines above that use a different schematic.

Yes I agree. Serial numbers are a must. Again thank you for this schematic. Saving me a headache with a power probe and chasing around

Hi Nigel, came across your post when searching to solve an electrical problem on my recent purchase of a CAT 304CR.... the electric turn off engine is not working. The solenoid is would when operated directly from a battery. Any electrical drawings or ideas would be appreciated its a BTN serial number

If the stop solenoid works when externally powered with 12v it's probably the shutoff timer has malfunctioned. You can test the wiring by applying 12v to wire 327 Pink ("Signal Out") at the shutoff timer. If the stop solenoid works then it's down to testing powers/grounds in the area of the timer. If they all check out, well......
