radio fuse blowing

[jake44]

so my radio and interior light died the other day, was only a fuse which I changed, on the fuse box it says 15a but it already had a 20a in the slot, so I replaced it with another 20a and now its blown again. and I have no idea why!

both times the fuse has blown the clock has gone very dim and every time I turn the ignition on and off it resets at 01:00

im about as useful as a chocolate teapot with electrics so any help would be good!

cheers

First of all i'd take the radio out and make sure there is no bare wire that is shorting out on any metal anywhere(i've had this issue).If there is cover it as much as possible so no naked metal is showing with electrical tape. And replace the fuse with the proper 15A one.

Make sure the ignition is not on and the keys arent in the ignition when you replace the fuse
