High Output 220 Amp Black Color Custom Alternator Compatible with Chevy Chevrolet GM GMC Cadillac Oldsmobile Pontiac 1 Wire Self Exciting 220A 65-85

The alternator came sooner than expected. It showed up in great condition. Went to installed. Went in without any issues. There was one slight issue with it charging but after a little back and forth communication with this company we had it worked out and everything as it should. Great product and great company to deal with.

For the price it works just ok. But like mentioned by other customers it does not put out the rating they give it at all. At 3500RPM engine speed it only puts out 110 amps max. Which is 40 amps less then the advertised idle speed and only half its advertised continuous max. Tested with 3 ammeters (2 digital and 1 analog). So for those of you needing a true 150 to 220 amps for competition stereos or serious off road accessories, dont buy this one.

Bad ass alternator. Put it on a diesel swap contacted seller for double pulley option. Arrived as expected. Led light sound system glow plugs starter big cooling fans Saul batteries all fire hot cause this alternator. I even had a high amp cable sort to ground catch fire alternator still works great.

so i bought this to replace my alternator on a 72' c20 it bolted straight up perfect the the sb350 so 9/10 on the fitment but the pulley was too large of a diameter so it wont charge unless im driving over 2k rpm and when it does it only goes up to around 12.8-13.1v this is a little weak and easily gets bogged down below 11.0v when running my accessories the old alternator would hold at 12.5v with everything on and sit at 13.8v for charging i have all incandecent lights and running ~1600w for the stereo plus and electric fan and water pump so my power demand is pretty high but 200 amps should have been more than enough i will be replacing soon for a proper mechman alternator but for the price and convenience i give it 3/5 it works but kinda sucks

I put 2 of these on my oldsmobile.Seems to be running pretty good I just wonder is 220 amps they put out?. I don't know.

So I bought this alternator for a jeep i go off reading with. Within 200 miles it smoked. I knew my warranty was out so I took it apart. Two bolts were cross threaded and loose. I took a picture of one. It caused the diode to burn up in the rectifier. Total poor quality. Now it’s going to cost me 60.00 plus tax to buy a rectifier!! Believe me with inflation and groceries sky high I don’t have the cash for that. So take it for what it’s worth. This happened to me. I won’t do business ever with this company again. Poor workmanship.

Great product, just be sure to order the correct adapter if you're using it for an old school.DO YOUR RESEARCH

Best alternator ever works perfectly 14.4 volts with every light on and fans no dimming also the company is extremely responsive and are good at answering all my questions
