I have a 2000 GP 760, I keep having to charge the battery, even after a fulls day use. Do I have a short? How can I trouble shoot it? It will drain down overnight parked on the trailer.
if your battery was close to dead and froze during the winter,then your battery wont hold a charge anymore,id unhook your battery ,charge it and let it sit for a couple days,if you still have power after couple days,then its obviously a short in your wiring and not your battery
