  • Does the trick as a one-wire alternator
Size: 105A Style: 7127-SE105 Alternator
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. ... show more

  • It fit like, perfectly.
Size: 105A Style: 7127-SE105 Alternator
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. ... show more

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.

  • Works well, good price, very loud
Size: 105A Style: 7127-SE105 Alternator
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. ... show more
