I recently had a issue with revering my batt cables. My reverse polarity fuses blew as did my antenia booster fuse.
I have replaced those fuses and the battery. Things "seem" normal except my converter fan now seems to run continuously, and while pulling / installing fuses for testing, I get slight sparking at the fuse slot ( TT is plugged into 120 and batt is connected).
Is it normal for the sparking?
Thoughts on fan running continuously?
Multi metering is reading 12.40 at battery (disconnected).
