I take alt down to the shop , the diode trio is puked, they fix me up and I'm out the door in about 30 min they said it'll go again . I'm only zingin this about 6200 through the lights and I'm using a small March drive pulley. I thought stepping up to the P Master would end this but I guess not. Any ideas or should I carry a spare.

And what was their reason that it will fail again, sure isnt the revs

I'm electric Dumb sorry Alt's produce AC power... the diode bridge is there to convert the AC into DC power(3 + diodes and 3 - diodes)

I doubt thats the problem though.....I run the same alt on the street and strip...no problems here. I'd say 10 gage is way too small...especially when running all the way back to the truck. I still run my battery up front and I run 1/0 gauge wire...it's overkill, but that's what I would run if running it to the trunk too.
