Caen Fred Posted February 24, 2009 Share #1 Posted February 24, 2009 I will make it short (ha ha). Erratically the electrical power goes dead. Not just the headlight, but gauges, turn signals, warning... the full monty!I have an upgraded 60amp Alt, an Optima battery, and a std 1972 240zThe alternator is good, I converted my car to FI and I am able to read my ECU on a laptop with an USB connection and it gives consistent 13,5 - 14 amp all the time, even when all is dead. The ECU and fuel pump is on a separate loom coming from the battery, so the car still run when the old system is acting funny! Link to comment Share on other sites More sharing options...
JonnyRock Posted February 24, 2009 Share #2 Posted February 24, 2009 You've got proper ground (bare metal) and solid terminal connections? Link to comment Share on other sites More sharing options...
Caen Fred Posted February 24, 2009 Author Share #3 Posted February 24, 2009 I think so as the FI is working fine direct from the battery?Is there an other ground to check beside the main one? Link to comment Share on other sites More sharing options...
Caen Fred Posted February 24, 2009 Author Share #4 Posted February 24, 2009 Hmmm, it's mostly when I put the lights on that ALL goes dead Link to comment Share on other sites More sharing options...
Walter Moore Posted February 25, 2009 Share #5 Posted February 25, 2009 Look for a loose connection either at the fuseable link connection by the starter, the amp meter, or the main fuse box. It sounds like you have a high resistance connection somewhere that is restricting the current when you apply a heavy load. It might be a failing fuseable link, but I am not sure it they can fail in this way without burning through. In any event, I would try to find this quickly because a loose connection is likely arcing, and that will eventually cause a fire. Link to comment Share on other sites More sharing options...
Caen Fred Posted February 27, 2009 Author Share #6 Posted February 27, 2009 Time will tell... but after a slow check of everything... I found a 4/5 broken connector at the alternator. Invisible if you don't have the nose on it I don't believe in cursing and voodoo:finger: but now that I have fixed my electrical system, the tank is leaking :disappoin Tell me, how does it feel to have a normal life?
