Recently purchased a new toy. 95 VW camper van. Simple system, start battery and house battery. House is charged by engine through a selenoid or via shore power. Second day of our first road trip killed the house battery because the selenoid failed. Would like to add a circuit to show the house is getting charged. Have a couple ideas. Electrical Guru's what do you think? One pic shows a warning light. I think I will use a volt meter instead. I only want to show charging when the engine is running not house battery voltage. Have a seperate system for that.
Do you have a schematic or model no on the alt? There should be a terminal for an idiot light — you remember those olde dashboards? ;-)
I've seen a number of RV installs which use an ACR with a remote light on the dash.
