Well a few months back before I headed overseas once more I had a problem with the car only running while using jumper cables.
As soon as I removed the jumper cables the car simply stalled - the fitted battery was quite flat but expected that the alternator would keep everything running
Anyway I tried to test the alternator in place and didn't see any voltage increase when I fitted the battery from our other car (a Saabaru 92x) so then looked at the 75A fuse and all looked OK so assumed the alternator was goosed
Tonight I was looking to source a replacement alternator online and happened to notice that Advance Auto Parts do free checks of the alternator & starter motors, so I unbolted the alternator and headed off to Advance Auto Parts fully expecting to be told it was shot.
The result was that the alternator is working perfectly...
So this leads me to the question....what can be wrong with the system?
Do these 75A fuses sometimes appear to be OK but they have blown in some area that's not visible?
Can anybody advise me of a simple logic test to narrow down where the problem is?
Cheers in advance
