I have a Stacer 399 Proangler with crank battery (rear and charged by my outboard) and a 100amp hour deep-cycle forward for my electric, that I recharge after every trip. I purchased a simple 2 battery condition gauge from BCF, which has three wires coming from the backside. It came with no instructions and I have searched the Net to try and find out how to wire it up, but to no avail... can anyone help?
There are two red wires, one to the left and right terminals of the double switch with free ends. A centre red wire on the double switch goes to the positive of the gauge. Nothing is connected to the negative terminal on the gauge.
