hi shop shark, my truck is 1950 and the previous owner has sure messed with the wiring. i have started to replace parts of it and found some of the old wiring to be falling apart. the reason i mentioned the alt was the actual rattle sound isn`t there all the time but when it is there my amp guage needle goes up to full amps which made me think that my alt might me intermittantly pushing out to much which might be blowing fuses. i have corrected some loose connections on the front and rear lights and checked the earths.
another thing, both my headlamps have also blown.
i just want to fix this silly problem so i can start enjoying my truck before winter sets in.

thanks

bill.
