12V Appliances do not run unless engine is running

Hi all,

On my Itasca, for whatever reason, the 12V Appliances (power step, fridge control board, water pump, control unit) do not run unless the engine is running, AND the battery mode switch is set to the Dual position.

When hooked to shore power, the 12v lights all run with the engine off, but none of the other 12V stuff. Am I missing something here? I shouldn't have to have the engine idling to run my fridge.

Your Itasca Windcruiser is the Itasca version of the Winnebago Elandan with a few styling changes. You can contact Winnebago Industries and they will send you wiring diagrams, build sheets, etc. for you motor home. You can get the 1990-on wiring diagrams here: Wiring Diagrams

What you are describing does not sound right. The first thing I would check is the power supply underneath the settee to make sure all of the fuses get power when operating on house batteries and that the house batteries are delivering full voltage. Also check if your electrical appliances work on shore power.

The dual battery switch controls the battery connection through two solenoids on the front left firewall. They might be acting up which can cause quirky electrical behavior.

I don't think this will solve your problem, but hopefully it will get you going in the right direction.
