NO STAR!!! >15 hours! Garbage!!!
I fixed up my APU! New skins, filters, fuel pump, A/C clutch, and this new DB Electrical alternator. Purrs like a kitten. LOW miles on the truck last year. All local, no OTR, NO use of the APU. I just left for my first OTR trip Monday. The APU runs like new. Third night; Wednesday, I noticed 14.5 volts on the gauge. I double checked with a multi meter; 14.5v. I shut down the APU, started the truck; 14v on the gauge. Started the APU again 14.5v. Went to sleep, woke to 12.2V. I assume the voltage regulator??? This garbage didn't last 15 hours. and that's including original testing!!!! Good luck!!!

Works for me
It’s about 3 1/2 cheaper than the OM one, exact feet, instead about two months ago, works perfect since than.

Bad alternator
Order the first one, it didn’t work right from the box. Got a replacement sent to me, 14 months later it quit working! I would not recommend this product! Now I’m down in Florida with 85 degrees weather and my reefer quit working because of the alternator!

Money saving alternative solution
affordable compare to genius thermoking part and work perfectly fine, being using 10days with no problem, keep battery charged at 14.0v, like the original one, the only problem is you have to trim the out case a little bit, cause the casing is fatter than the thermoking ones and has interference with other parts , but if you are a DIY guy like me, it’s not a problem anymore,just use a grinder and cut a little bit, and you can save a lot of money!

very glad I did
Used on Tk Sb210, I thought I'll give it a try since Thermo king is so expensive, very glad I did, good quality, so far a year on the unit no problems, still going.
