Some Electrical ?s

[55 Fargo]

Hey all, my truck is a combo of 1952/55/56 Dodge and Fargo trucks components. The chassis, and drivetrain were a 55, but it came with a 12 volt 56 starter, so it became a 12 volt for Me right there and then.

All is okay, using a GM 10SI 1 wire alt, again no problems whatsoever.

I currently do not have the gas gauge hooked up, or the water temp gauge hooked up. I am using a mechanical water temp gauge, but have the the stock electrical gauge and sender ready to go.

How many of you have not used  resistors in line, I have tested these gauges on 12 volt without a problem, do I really need a Runtz voltage dropper for these 2 gauges?....thanx

Hmmmmm, 37 views, and no replies, must be a juggernaut of a question...........LOL I did the search, I know Coatney did not use any voltage dropper for his gas gauge, and it works fine....

If Don says "no problem" I'd believe him.  Keven probably has a bunch of gas gauges if yours blows up. I've looked at going with a 6V-12V converter but it ain't cheap.  How expensive is the resistor ? Is it a simply soldering a resistor in place ?

yes the resistor is cheap, but so am I......LOL 1956 was the 1st year for 12 volts, in these trucks, what did the factory do in this case? thanx Hank

You'll know in a fraction of a second once you turn the key on.  Don't ask me how I know.  I got anxious to see how it started on 12-heard a "tink" as soon as I turned on the key in the 36 Plymouth, and I immediately realized what I had forgotten to do.

dropping resistor to the ignition...CVR for the gauges

I have tested the gauge\e on 12 volts already, without any ill effects. I used a GM sender, and jump wired to gauge, it did work, in the opposite direction though, as the sender is GM an old 60s style, might be 0-90 ohm
