Melted Alt?

i have a newish 105 amp powermaster CS103 style alternator. Today is the first day I've driven the car since installing it, and my Spal Dual 11" fans. After tooling around near my place for a bit the gen light came on and I noticed the voltage meter was only reading around 11 volts. When I revved the engine it did not increase the voltage.

When I did the conversion I installed a new power tap point on the firewall where the voltage regulator used to be for power distribution and the alternator's red sensing wire. I hooked up the brown alternator wire to the blue lamp light in the harness. It's been working well for the last few months as I've driven it around the parking lot. But today's excursion proved to be too much.

I double checked all the wiring and appears to be correctly wired. I then took the alternator to Pep Boys to have them check it on their machine which indicated that it was performing within the correct ranges.

I visually inspected the unit and noticed some crispy bits inside.

Did I somehow fry my alternator? If I get a replacement is it likely to also fry?

THIS CAN'T BE GOOD:

Re: Melted Alt?

As long as you didn't stick a screwdriver in there or something that caused the windings to short to the frame, I'd say you have a defective unit and should return it.
