Default What happened?

Good morning all, can someone please explain how this happens. That's the voltage regulator that left me stranded. When I got home the battery was dead. Battery is only 2 days old.

Looks like it shorted out. Of course that will kill a battree.

No clue what caused it, but definitely a short is what smoked it.

You should do a thorough check on the stator or replace it outright. The battery might live after a long slow charge - worth a try.

Good part is, you now have a pigtail to cut off the regulator you can use for stator test purposes.

I was able to salvage the battery, charged overnight. Going to check the stator after work. Didn't think about the pigtail, thank you.

What was going on before and why you replaced battery?

Bad regulator which caused my battery to swell up like some dude on droids.

IDK what we lookin at...but as an assumption (dangerous) I thought there were 3 Wires on regulator...one being rectified and regulated DC out to battery...the other 2, are AC in from Stator!!
Last I knew AC was as sensitive one way as the other...meaning high current at one was also high current at the other..
So...By My Thinkin... either the wiring on one side was physically damaged, touching ground...or something else external got very hot indeed...
I doubt anything to do with the DC side....which I assume (there I go again) is the lead on the far right...

So back to beginning, was new battery and regulator I assume.

Did you check stator? I assume two wire two phase. Proper AC on both and no shorts to ground?

I would be suspicious of a bad connection at the rubber boot connection point where the regulator wires plug into the stator at the engine block. That is the first place I would look. YD

Haven't tested the stator this time but checked it last time and it was good.
