Alternator Bosch or GENERAL MOTORS

Voltage regulator is built into the alternator. If you're seeing 14.5 V with the engine running it's as good as it is going to get.

ran this one a bit in my 88 16v scirocco. works fine. a bit biger than the sotch as far as size.

A few hard lessons I learned: Have a voltmeter and ensure your battery is good, a bad battery will kill a good alternator (12.6V min on non running car) Find a reputable guy that rebuilds starters and alternators and try to get your alt rebuilt or find a new Bosch.

I would try replacing it with a stock Bosch alternator.

Got it. So am I correct in thinking that these Bosch alternators have both diodes to get to DC and voltage regulators to make it a clean voltage?

Welp... the alternator AND the battery are dead. New battery is in, now to do the alternator but I need food first. I was amazed that the store had a rebuilt Bosch alternator IN STOCK

My 05' Golf TDI came with a Bosch unit from the factory and lasted about 90k or so, I replaced it with a Bosch Reman and its been doing well, 120k now.

I recently replaced my alternator with a new Bosch. It has been running fine now for about 300 miles. Now however my alternator light is coming on.

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.

Ok so I exchanged the alternator but just got it on this morning and the alternator i exchanged it with was a bosch which is a direct replacement of the original one i have, i hooked it all back up properly, new charge wire and its running at 11.4 volts now and still drops lol.
