Problem solved.... without any new wirering.
The solution was as trivial as it is embarresing.. so I will not trouble you good people with it..

He he.. ok then..... Its really rather silly...
After installing the alternator I started the engine to see if it was working/charging.. witch it wasnt.. apearnatly... well.. as it turned out.. the engine was cold!!... that meant that as I was bouncing the throttle to get the charge light to go out, the carbs was choking thus not reaching high enough rpm for the system to start charging.....doh!
Thus the fault had nothing to do with the "AL-TER-NA-TOR".. but everything to do with the "O-PE-RA-TOR"..

Guess we sourted out who is buying the beers tonight eh?..

HAR HAR HAR HAR!!!

Not to mention that we probably all could have done the same!

The worst example of this I've had was when our first Espace broke down. It happened just near our house and I had it towed home. It took me ONE WEEK to figure out that it was the timing belt that had broken. Ok, I thought it couldn't be as it had been replaced just 11 months earlier, but still. I had ALL sorts of odd thoughts while I tried to figure out what was wrong. I even replaced an expensive cam sensor (I still have to old one). Fortunately the mechanic did the repair on his and the belt suppliers expense and only three valves were bent.

But my wife still pokes me with that one and I've promised her to let the garage handle her car in the future - besides, now it's registered as a company car so it doesn't make that much difference and my time is also expensive

Well I did a testdrive, and so far things seem ok.. though the fanbelt are squealing again... so I guess I have to get underneth the murena once more... this time I will get someone to fasten the bolts for me while i pull at the alternator

Erhm, - I would expect the system to charge even in idle - with the choke on ?
I don't recall having ever seen the charge-lamp on under normal conditions - except while cranking, or after turning the engine off.

We have the same issue with the mercedes GD in the army... you also have to rev them a bit for the alternator to "wake up"

..
After that it does charge in idle.
Anyway... tightened the belt again... and that seems to be the end of that....

Does anybody know what the little square box on the upper wire on the alternator is for?
My guess is thats some sort of noise filter.. but I'm not sure
I'm replacing the alternator of my murena with a 80amp one tomorrow ,in the middle console on the 55 amp there is a "L" and "+" connection, where there is just the "L" on the 80 amp.... think I should worry ?

Hello,

I wish made the same on my murena 1,6L, it is possible ?

Have you got any ref ?

The wiring loom from the alternator needs to be upgrade by bigger wire section ?

Thank you

Mathieu
