Hi guys,
I've got an issue I hope can be resolved here. I have a 4.2TD GU Trayback. I have been getting flat batteries when left for a week & have been jump starting it while trying to sort the problem. My alternator is only putting out about 12.4 volt so I'm guessing that's my problem there.
When I jump started it a couple of days ago I lost my ignition lights & can't get them back. I only realised when the tachometer wasn't working. I turned it off & proceeded to check all fuses, both in car & under bonnet, all tested fine. I tested all the fusible links & they tested fine. I have power to the alternator both to the nut mount & white wire with red stripe at the plug, the exciter wire I think. The other white wire has zero voltage. This is all with ign off. I have checked all earths & they test fine. The ignition barrel wiring tests ok. I pulled the dash & checked all connections & globes & they're all fine. I also checked all relays & they check out good as well. (I went so far as to hotwire each plug for the relays to be doubly sure). While I had the dash unplugged I tested for power & only found one pin that had continuous power with ign on. I might add that the truck starts & runs perfectly well....
I have since stripped & cleaned the alternator & it is now putting out 14.1v, which I am happy about :)
This is really starting to do my head in.
Anyone got any ideas fellas????
Cheers..............Pete!
