Need some help guys, the Lux is my daily driver right now. Long story short, was driving to work today and lost power windows speedo etc. did some searching and found the ECU IG fuse blown. Replaced it and made it about halfway home before it blew again. Nothing to report operating when it blew, no lights, reversing, not towing etc. got home and it would blow the fuse immediately upon engine start.
Checked and noticed alternator wasn't charging so I suspected the fusible link, opened it up and noticed it has been bridged with solder at some point (SA market) after it cooled off I started it and put the ECU IG fuse in and it's all good and charging so maybe the alternator isn't hosed, hard to say how they blew the fusible link. Ordered a new fusible link assembly from Aus.
This leaves me with why the ECU IG fuse is blowing, I've looked at a lot of old threads and checked my trailer plug wiring and everything I can think of. Can anyone offer a good way to narrow down the likely short? It's my daily right now and obviously I'm on my own with a long lead time on parts. Cheers
