vs
Alternator OEM BMW or GENERAL MOTORS
Reviews
If you have the V6 4.3 it's one of the more dependable motors GM ever made. The factory alt is rated at 105 amps. Should be enough for your needs.
Pros: dependable motor, enough amps
Paid $1,214 out the door. Alternator... No experience with cars and don\u2019t feel comfortable installing myself. Based off local availability, I can\u2019t imagine an option I would\u2019ve been happier with. Of course it\u2019s overpriced, but I can justify the spend based off how seamless the experience was.
Pros: seamless experience
Cons: overpriced

Had the same issue a few months back. Put in a new alternator and it’s been perfect since.
Pros: perfect since

You need to try using a OEM REMAN or OEM NEW alternator. Aftermarket items can really affect BSD.
Pros: affects BSD
Cons: aftermarket items

Here is a stock Mk2 65 amp alternator (top) and the generic one-wire GM alternator (bottom). They're physically the same size, and the posts are almost identical in length. The GM fan is indented in the center though, and the VW one is flat. I used the GM fan, cause my stocker is disgusting, lol. I swapped the VW hardware/pulley over, since the GM pulley was obviously no good (flat, not offset).
Pros: same size, easy swap
Cons: GM pulley no good

Triumph TR7. You're a bunch of amateurs. I'm a British car guy in general but the Wedge was exactly as bad as advertised. When it couldn't keep a battery charged I converted it to a GM alternator, then the radiator fell out. A previous owner had pop-riveted a license plate over a hole in the floor. Keeping the carbs synched is a black art. The seat frame snapped as I went down the road - I later found out that it had been hose-clamped together by a previous owner. It didn't catch fire as many times as my Spitfire has, but at least the Spit is fun to drive. The headlights didn't just pop up out of sync, they popped up and *turned on* on their own.
I've also owned a Hyundai Pony and it was a Toyota Cressida next to the Wedge.
Cons: radiator fell out, carbs unsynched
