Lou and Boilermkr,
Thanks for your help. I replaced the small fuse with a new inline fuse holder and 25 amp fuse with larger spade. When I attempt to charge, the new fuse does not get hot. However, the charger lights up the light showing it's plugged in to power (second light from bottom), and the light at the top which I assume means full charge. When I first plug it in, it shows the power light and then the light immediately above it but within seconds the light moves up through the other lights until only the top light remains lit. When I turn the key, the battery meter on the dash shows 37% and doesn't change. What would make the charger not charge as if the battery was full like that?
