Electrical fault. Check wiring underseat fuses, and check earth connections in same area. Even use a jump lead battery negative to underseat area, and, or bulkhead.

Check battery earth strap. I would remove chassis end and clean up and refit. Cheers

What they said plus it’s a good idea to run a ground cable from the casing of the ECU direct to the negative battery terminal. My temperature gauge would often ‘spike’ into the red momentarily and lose power. Never done it since I grounded the ECU casing. I’m saying grounded when I really want to say earthed, but I’m trying to speak a bit of Canadian.

Side note, but I believe grounding to be the more appropriate term especially since a car on rubber wheels has little connection to Earth. It's obviously the negative battery terminal that is connected to all all the other negatives (zero potential between them). According to AI both terms are not the most suitable
Earthing Earthing refers to connecting a circuit directly to the ground. It protects against electrical spikes and potential damage to life and property. The wire used for earthing is typically green in color. Grounding Grounding means creating a zero potential in a circuit without a direct connection to the ground. It provides insulation against accidental currents and helps prevent overloads. The wire used for grounding is usually black in color. |

Thanks to all for the suggestions.
Trying to chase the electrical fault now. There are many many added on wires and bits in this thing. I also may have the “oil in the ECU” problem, the wiring is pretty oily. Is that just an extra problem or is it possibly the fault? Feel free to talk to me as one who needs things explained slowly and with crayons. Cheers, |
