Alternator belt
Hi
I have a 1989 Turbo 2 with a new engine
It has done 1000m and I have nosiest that it is wearing out Alternator belts
As it wasn’t running when I got it I can’t say if it was doing it before
Any help would be appreciated

I have this same problem too. About 1500 miles on a belt. Spacer is on the back side of the alternator and the pulleys appear to be inline. The belt does not shred... it just elongates.. i need to tighten it constantly, then it just reaches the end of the arm..... lots of black powder....? The belt material seems very soft to me, but I can't imagine the two belts I installed were bad.
BTW... its a JDM replacement T2.

OK, I finally understood the problem and fixed it a few months ago. If you removed the air pump, your alternaltor belt is carrying the entire water pump load and there is nowhere near enough belt wrap...it basically just skims the side of the water pump. At high speeds or rapid engine wind ups, the belt slips on the water pump pulley..wearing heavily. I purchased the dual groove pulley, installed it with two new belts at the same time. I has never been a problem since. Your other choice is to go back and install the emissions air pump and its belt which to me cluttered the engine compartment. Hope this helps and good luck!!!!

notice the same.
Started with killing 2 belts in 6 days, altenator broken.
Now i got a brand new on it and after a few trips i also noticed black powder. So apparently it was still slipping.

J9, I don't think it's the belt or anything other than wiring now.
I disconnected the B terminal from the alt and unplugged the connector, started the car and she didn't make a sound or heat up the alternator at all.
Is it possible I have a short or something somewhere?
The guy that helped me build my engine says just switch to dual belts and I won't have that problem, but I don't have the extra money to spend and I run a yoohoo belt.
Do I have too much resistance somewhere? Where do I need to check with the multimeter and for what?
