Yes I have the 70amp alternator. I'll see if I can get somewhere to load test it so I'm not chasing electrical gremlin theories I guess....

If the alternator is the issue I would like to upgrade to the 80 amp...any bigger and I think it'll steal too much hp which I lack as it is with A/C on. How much would the 80A steal from me?
