Here is what I lose:
Tach, fuel level, oil temp gauge, volt meter. Then the red alt. Light is on, but car runssmoother, it was not right before that. This is a 75 2.0. D-jet new coil not long ago, I have a hotspark module, no issues with it seems to be fine.. Had been running really good. All lights stay on except I think the brake light, that could be the culprit? . I will recheck that. What else is on this circuit? I thought tomorrow I would disconnet the fuel level sender, maybe that is the cause? |

Might be putting my head on Krusty's chopping block, but here goes:
A lot of wires go thru #9 so it is a common problem with a lot of possibilities. Try this: rig up an inline fuse and ammeter across #9 terminals. Turn key to "on" and operate controls one-by-one (turn left, turn right, tap brakes, turn on park lights, etc). If you have a constant short you should be able to isolate the problem circuit. If you have a random short, good luck! In my case it was a short on the emergency lights switch. A huge pile of wires merge there. The rubber insulators on them are likely in bad shape and an opprotunity for mayhem. |
