Electrical fault somewhere

I think the problem is not the alternator but the conection in the 120Amp fuse to the main engine fuse box.
The actual contacts to the spade fuse are enclosed and the contact area cannot be cleaned (scraped) easily. The fuse does not pull out like the rest but is bolted in with two bolts (one 8mm and one 10mm) No one knows this at first, release the bolts on either side and work the spade fuse up and down many times to score the contact area.
When I first tested it it was showing some 20 ohms with a high impedance meter but after it was cleaned it showed close enough to zero.
The high resistance connection on the 120Amp fuse may have caused a volt drop (with all systems on ie engine, air, wipers, and headlights) sufficient to drop out the engine relay and it conk it out. It starts again readily but the low voltage may cause the stop light warning light to come on.
Volvo had the car for two weeks and couln't fault it after I did the clean and replaced the engine relay - but they didn't charge me - so good on them. They quoted me $1400 to fit a new alternator saying they had seen the problem before and they replaced the alternator and the cable which may have inadvertantly fixed the bad connection on the 120Amp fuse.
I worked for Volvo Truck for a couple of years as a contract Production Engineer but when sales went down I was moved on - guess I was too much of a smart arse. Renault owns them now - predictable I should have thought.
