I've been having the 10 amp accy fuse and the 20 ? amp guage fuse blowing lately, but they last a few days before they blow. The quickest they blew was after 30 minutes (accy fuse) of driving, on a flat no-bump surface. Could it be that the circuit has slightly too much current, like 11 amps, going thru the 10 amp fuse, and it takes a while to blow it out ?

I've already disconnected the lighter completely, and it still blows out, somewhere between a half hour and 4 hours of drive time, bumps or no bumps.

Thanks

 

Anyone ?
