Alternator Bosch or Denso

For anyone looking for a drop in upgrade, I used a 105 amp for a Suzuki. Made by Denso. No harness needed, plugs right in. Going strong for a couple years now in my 3rd gen.

I just replaced mine and went with a denso reman. They are the makers of the oem alternator so I’d trust them more than other brands.

This is a known issue with non OEM and especially bosch alternators, the regulator gives a different signal to the power control unit.

If you were family or my customer I would get the Bosch.

Denso is likely the OE manufacturer, as they provide a lot of MOPAR OE alternators and I know they do for the T&C/Voyager/Pacificas.

I’m in the Boston burbs, I got the alternator replaced for $350 with parts (remanufactured OEM Denso alternator) included 3 years ago. $450 sounds about right.

Way too much, 2007 accord my son paid 425 for a denso alt.

Honda Alternators are crazy expensive. I don\u2019t recommend aftermarket unless you can get a Denso.

On day two, the Denso overheated and failed, the diodes had burnt out. I replaced it with the stock 70 A Suzuki alternator, which failed the same way on day four.

I picked up a 07 jetta 2.5 from the auction for a good deal and only 95k on it. The problem is the battery is not charging, figured ok needs new alternator put a bosch unit in and it is still not charging the battery. Put multi meter to the post on alternator and it is only putting off 11.5v.
