1 Wire GM Alternator SCITOO New Self-exciting Alternator Fit for Chevy High Output 12V 105Amp 10SI SBC BBC GM Replace #ADR0335 7127-SE105 400-12340 ADR0151 20-102-7

Easy to install It fits just right on the 1975-78 Cadillac, though the app says it doesn't. It is a little noisy, but l don't mind, as it works well.

Great product for the price it works great and no problems installing it..

Ok. This was for a 1980s dump truck with an odd ball 366 BB. When I received the alternator, I noted how well it was packaged, I was very happy I had to “clock it” thus gave me the excuse to open it up. Let me tell you, the inside was perfect, green grease in the bearing even. The price was right, but the quality was worth 2 times of that.

6 months after purchasing and very few miles put on it and the alternator is not working properly and going bad. Took it to a mechanic and they said it was junk.

I don't have a way to measure if it really outputs all the way up to 105A. My battery does seem to be charged, so it seems to be at least good enough. It is much louder than my last alternator. A high pitch whirring/whining sound that competes with the engine and (mechanical) engine fan for who's loudest.

Was worried when I got it because the pins were facing the engine when installed but it was easy to clock it the way I needed it. also turned out I didn't need the pins because it does actually function as a 1 wire (just the charging wire) alternator, no wires attached to the pins. I did read that it may need to be manually excited by connecting the excite pin to the output momentarily while its running when the alternator is first installed, or if its been not ran in a long time to get it to start charging, mine did not need this however. Do have to rev the engine up to about 1500 before it starts charging but then it stays on after that which is why I was replacing my old one. Not sure if it really can produce 100amp but its doing well so far. Oh also the finish is not the same as in the picture, mine came silver fan and black pulley.

Worked great at first then problems started. High pitched noise on and off. Voltage was 14.2 when installed and now is 12.2 or less. Cannot keep up if lites or air is on. Only used for a few weeks

Used this for an old Clark forklift. No complaints, and was happy it came with the small rubber plug for the two spade terminals. But I have it setup simply as a one wire alternator. A quick little rev of the engine and the alternator wakes up and does its job, charging at approx 14.5V. Would buy again, and will update review if it fails; I’m good about that. I was hoping to switch my dual belt pulley from the old alternator to the new one, but the new one has a shorter shaft that protrudes less from the body. No big deal, I just used the single belt pulley it came with and am using one belt instead of two. No complaints, no problems.

I've ordered a couple of days so far always work good for the price

like oem good quality

The alternator fits and works great the pulley was a bit smaller than my original I couldn't swap pulleys because the shafts were different. But it works ok with the smaller one just turns a bit faster.

Excellent

Belle qualité
