Type "A" vs "B" generator?

[scott.hibbs]

Guys, I could use some input. I went to an
ignition shop yesterday with my generator (yes
generator). It is stock on my 140 hp LOM
engine. The owner told me that my generator was
type "B" and most regulators are type "A". When
I pressed him for details, he could not tell me
what the difference was, only that I would have
crispy wires if I used a type "A" regulator. He
believes it is simple to change the generator
from "A" to "B" but just does not know how.

Can anyone tell me what the difference is? I
searched the net last night and found nothing.
Also, is it easy to change to type "A"?

I'm not an expert (I did sleep at a Holiday Inn last night) but I
just happened to read an article lately that may shed some light on your
question. It has something to do with the failure position of the voltage
regulator if the regulator fails. If I remember correctly, type A defaults
to the open position and type B fails/defaults to the closed position.
Failure of the type B gives you a runaway alternator. (Article was
written for alternators, so I will stick with that.) Type A opens the positive
line and Type B opens the negative. Please check this info out. I'm
relying on memory and pilots shouldn't do that.
