Hi, I need to understand how the main and aux batteries are related. There is only sparse information in the vehicle User Manual. I believe all of my questions would be answered if I could see a wiring diagram. I found a service manual for my make and model on Helm Inc.'s website. It costs $350.00 Before I spend the $350, I thought I would try this forum. If there is anyone here who knows about the Aux Battery and is willing to chat with me about it - Your help will be greatly appreciated. I want to know how the Aux Battery is situated in both the cranking circuit (if at all) and how the Aux Battery gets charged (charging circuit) Additionally, a somewhat related question would be; What exactly is the Battery Gauge on the dash measuring? (main, aux, alternator, all 3, what?) Thank you in advance for putting up with such a newbie question. Guessing about things makes for bad troubleshooting. Just want to understand what I'm dealing with before I go poking around.
