Added second battery

[Kj20203]

I added a secondary battery and perko switch. Wired everything and now nothing on dash turns on and switches don't work when ignition is off. There is power after the main circut breaker.

What gives?

Is there some sort of reset procedure?

Are you sure the perko is wired right?

I believe so. the circut breaker is after the perko switch. with the batteries on, the switch has power.

Did you link the new house battery's ground post to the existing starting battery's ground post? Sounds like the helm BUSS ground cable got left off the battery. The helm B+ would either be wired directly to the battery, or left disconnected if that was the problem. Wired correctly, it would be on the C post.

Good call! Problem solved. Thanks!
