Brise - Denso alternator replacement VRMs - Thumbs up

[OliverSedlacek]

It seems that the voltage regulator module (VRM) has failed on my Brise ACR5021 alternator. Can I get a replacement from a Denso alternator of some description?

I have literally just this evening replaced the regulator in my Denso alternator, after I fried it at Spa last week. It's a type 1 connector rather than a type 2 of your Brise ACR5021, but if you whip the heat shield off the back, you should be able to see a marking so you can get a replacement regulator. Mine was £16 from eBay. As yet untested as I've not nailed it back on the car.

Photos and part numbers, please, Mankee. Once it's known to work!

Thanks

I found http://www.sahibs.com/ in Maidenhead and they confirmed the diagnosis. They replaced the module for me and retested the alternator, so I give them a big thumbs up. The chap also explained the known weakness on these Brise alternators, which is that the regulator will burn out if it loses the ignition switched battery connection. I also got an 'rapid payment' discount!

Thumbs up, recommended.
