Re: Dead engine batteries and a Dumb Question Reply #25 – August 30, 2012, 09:04:45 pm The boost solenoid is not a "latching" solenoid. Just sitting there, it draws no juice with the contacts in the "open" position. When 12V is applied to one of the small terminals, the contacts close allowing the boost function to operate. This is not done without a price with the solenoid constantly consuming a small but significant amount of electricity to keep the contacts closed. Unless connected to a solar panel or shore power, the supply battery will be flattened in a day or two and the idea of keeping both sets of batteries charged will be defeated. Pierce Quote Selected
