I've actually done a few 51-2 F1 thru F6s.
For fuel, temp guages and oil pressure guages a 6-12 volt reducer (a big resistor that as far as I know are still available) will allow them to to read correctly.
The Amp gauge is a non-issue. On these trucks the current does not pass THRU the guage. The main feed wire passes thru a loop in the back of the guage. The needle reads through induction. At worst during a high draw situation the guage would peg but it will not burn out or be hurt. I was running a 100 Amp Alternator on this truck with a ton of electrics to include a winch and parallel batteries with no problems.
I would suggest a complete re-wire if you have not already done so. The 56 year old cloth covered wiring is a fire waiting to happen.
Senders used to be available thru NAPA, but anyone specilizing in old trucks should be able to get them. Carpenters might have them.Last edited by Mike P; 10-22-2007 at 06:24 PM.
I've NEVER seen a car come from the factory that couldn't be improved.....
I saw last night on fb about John. The world sure lost a great one. I'm going to miss his humor, advice, and perspective from another portion of the world. Rest in Peace Johnboy.
