Good product
Have had this in my Tahoe for two years now and have no issues.

so far so good. steady 14.4V, easy to install into my Lada Niva 2014 1.7 and a great upgrade
so far so good. steady 14.4V, easy to install into my Lada Niva M 2014 1.7 and a great upgrade over stock 42A. 115000km's It just took 3 washers for the bottom bracket to get the pulley aligned, a washer under the pulley which came off of the original alternator and a steel angle iron for the upper tension-er bracket. I hope it will last, I will inform if it doesn't. 150000km's and it started behaving strange and didn't charge anymore. It could have to do with my failed dashboard which then probably didn't supply enough power anymore to the exciter? I have now connected the exciter (L) via 470 = Ohm 1 Watt resistor to KL15 IGN through a 1A fuse. The alternator charges flawless again. Before it was connected through the charge control lamp to (L). I would like to figure out which pin can be used for the charge curcuit indication lamp now? ... show more

Works well
Fit my 2003 Avalanche Z66 On Road Edition, where the enhanced ones don’t. Works as required, no noise.

Garbage, lasted less than a year and the regulator died.
It looked fine, fit fine... but In July about 6 months after I installed it the battery warning started flashing on my truck. I pulled the alternator and took it to a parts store to be tested. Test came back and the regulator in the alternator was bad. Sorry but if an alternator can't last a year on a truck that is used only on weekends then this is simply a bad product. Don't waste your money. ... show more
