Looking for help. I am blowing 30 amp fuse when I turn key to start, (I temp installed a reset breaker) I read some other posts to gather info, so far no luck.
1. If I remove glow plug wire the engine turns over, no breaker tripping.
2. If I remove the starter control wire the glow plugs glow.
3. I could not find a short (have the harness apart).
4. I bought a new switch and glow plugs.
5. I jumper wired the controller under the dash and safety switches.
6. Had starter tested at rebuild shop, and tried new solenoid
This is a simple start system, I must be missing something. I have a few pages from the shop manual for the start sequence and wiring diagram. The shop manual even shows the energy flow from battery to each component depending on start switch position. I have been to a local shop--they never worked on 7500 and didn't have shop manual. Any help would be great! Thank you.
