Gday guys, got myself a conundrum. Had the dual batt setup to the tub no prob for years. Went shooting a while back and the system cooked the fuse in a 12v ext lead, then plugged the light direct and sure enough looked like melted the solder on fuse here too. Ran a fridge at a later date no probs. Checked voltage. 12v off and 13.8 running. What should i be looking for... bad day (damp) or an earth leak?
Advice always appreciated
cheers
