Hello friends, I have a question about the main wiring off the cranking battery.
Let me explain the whole story. I have added several electronic upgrades and wired in a separate lithium battery to run them all. While I was at it I thought why not run all the boat power needs off the same battery and leave the cranking battery for just starting. So that is what I thought I did, on the main battery are 2 wires, one heavy guage for the starter I imagine and another one about 10 ga that I assumed ran the rest of the power, ie pumps, lights etc.
Well over the weekend I had an issue with my in-dash flasher (yes, I still have a digital flasher) shutting off whenever I started the motor.
So, my question is what is the 10ga wire on the battery powering and how is the electrical system powered?
I'm confused but I know one of my expert friends can set me straight.
Thanks in advance.
