Sounds like a bad alternator to me, I had one do this on my f150 and it would create large spikes in the charging causing problems just like he is describing, I would pull off the alt and have it checked at a shop not just checking it on the truck at say advance
Where did he get the alternator from? I got 3 bad alternators from auto zone 1 time I went and had my oem one rebuilt and all was well, but like the others say it could be a bad or loose ground
Jason, But you can call me Sir!!!
