First,the radio fuse is number 11/10A in the fuse box in the cab.It is fed from fuse number 1 located in the engine fuse/relay box.Your charging system 15A fuse you are looking for is also located in this box.I am sending you a picture of the engine compartment to help you locate the fuse/relay box and a picture of the fuse positions.
Drop me a line if you need anything else.Thanks,Chuck
I found and replaced the 15 amp in fuse position 20, but it didn't help. I thought the Chilton manual may have been referring to an additional fuse.Could the short have damaged something else between this fuse and the starter relay? Thank you for your help!
