Does any body know what fuse controls the radio and cigar lighter on a 123? I am using the cigar lighter power to run my fuel switches and gauges for my veg oil system, however they, along with my radio are now out of commission. All of the fuses look fine, but I still think that the fuse it the culprit. Thank you.
