2 group 75's under the hood a third group 31 at the amps and this... 250A 1998 - 2000 GMC Sonoma Jimmy Chevy Blazer 4.3L High 250 Amp NEW Alternator | eBay ... I know it's not a Singer or Mechman but it was keeping a solid 13.8V in the 4 ohm video... with the factory alt it was sub 10V before I installed the new alternator... so at least the new one IS putting out...Sounds like your prob giving them too much power.

Do you have 2 batteries under the hood or is it in your cab area?
