Testing Voltage Regulator

[careyo63]

Part# AL-1215 12V 15amp. is what Fredricks Outdoors is showing. My bet at 15amp. it's a Dynamo. I had to check Hoye and the #'s match with a photo. At that price if it was mine, I would check into a converting it to a Alternator with a built in Reg.. It's came up before on here I believe. Fred. smallest Alt. is 35Amp. and 40Amp. with a built in Reg..

I had a similar problem a few years back. I unbolted the regulator from under the dash and discovered some critters had decided to move into it. Gave it a good cleaning and blew it out with the air hose and all was well !

I wish I were that lucky. My regulator shows no conductivity between any of the terminals, i.e. completely dead.
