Hi!
I have a 1991 HR 34 with P-30 and I am losing 1 volt between the aux solenoid/guest battery switch and my Chassis fuse block ignition ( brown) wire under modest load.

My battery voltage is 11.98 at the aux solenoid and 10.8 at the fuse block under the dash ( chevy fuse block). I removed the guest battery switch to eliminate it as the problem

Assume corrosion somewhere but I cannot see how the 12 volts gets from the battery to the fuse block under the dash.

This is the dash gauges dance when the turn signal are on, etc. problem.

I also assume there is another fuse block with relays, etc somewhere but I cannot find it.

Hi !

Welcome to IRV2! We're sure glad you joined the gang!

You lost me on that one but wanted to say hello!

Good luck, happy trails, and God bless!

I've heard of the chassis battery, and the house battery, but not a guest battery. Could your voltage difference be the difference in the house and chassis batteries?

11.98v battery voltage for a 12v battery indicates only about 40% charged. Either your battery is damaged, very weak, or the connections are dirty.

The power from the chassis battery goes from the battery to the starter solenoid. From there it should go through a fusible link to a junction block near the alternator. It should then go to the main fuse block.

From what I remember there are a bunch of circuit breakers under the front hood. They get corroded inside and will drop voltage often to 0. When you find them run a voltage drop test across each one of them. That goes for any circuit breaker that you can find on an RV that is even a few years old. I had to replace about eight of them on my brothers 95 P30 about 3 years ago. On his, they put them on the firewall where any water that leaked through the hood would drip on them. You might also do the same with every ground connection you can find. Just google "voltage drop test". Learning it will save you a lot of unnecessary searching and parts replacing in the future.
