I was wondering if anyone can help me with a possible problem with my 3 bank charger. I am not sure if this is a standard charger that comes with all blazer boats, but i think i'm having a problem with mine. When i plug it in, i see no a/c light lit up, but when i push the test button the number 3 bank lights up and that's it. I have my cranking battery hooked up and 2 Yellow top Optima Gel batteries hooked up to the other two banks. Is there any way you can tell whether a charger is doing it's job without being a electrical theory guru ? Any help would be greatly appreciated.
