Wire the batteries in parallel. + to +, - to - to ground.
That's an easy way, or if you want to keep one isolated as a backup you can wire in an isolator relay. Say you spend a lot of time running your radio and want to be sure you can start your truck afterwards. Wire the relay to be controlled by the main ignition(pink wire, green plug at bcm, stays on during crank). Either way works, just depends on your needs.Quote:

I ran my yellowtop and Batcap in parallel with a 250amp alternator... no problems, even pushing 3200 watts for two hours.Quote:

Isolated is a different story. I can give you a write up tomorrow if you need it. It's quite simple. I'm just too drunk and tired tonight.
sounds good send it whenever you get a chance
Fairly just this right here is exactly what you need to see...Quote:
