I was asked a question a few days ago by another member about where to buy a "Vol-ta-drop" voltage reducer to run 6 volt appliances on a 12 volt system.

I checked today with the folks at C&G Ford Parts, the "Vol-ta-drop" is no longer being produced, and there currently is no substitute.

So, for those of you who may be converting and are not going to be able to completely replace your 6 volt equipment; and, you had planned to use a "Vol-ta-drop" to reduce the voltage to that, you best find one and buy it now. There may be a few left out there somewhere.

Just thought I'd let ya know!

 

good thing i gotz new 12 volt gauges then ...............

 

Any one looking for a drop resistor for their gauges might be interesting in this HAMB post:

Great info , Thanks Bob

the 51 f-3 I picked up last month has been converted to 12 volt but I dont think they did anything to reduce the current at the gages?? they all seem to read really high? but I have only driven it once so far so I wasn't sure where normal should be?

 

do u need this for anything else but the guages? how about a stock radio?

are the ones in the lmc catalog vol-ta-drop?

 

You need drop resistor for any of the electrical part that run on 6 volts. The starter is the exception, you can run a 6 volt starter on 12 volt for short bursts, as long as you don't grind away on it.

 

Just to clarify,

They still make the small voltage reducers that drop the voltage on the gauges. The "Vol-ta-drop" was a very popular, fairly large, ceramic voltage reducer for use with heaters, radios, wipers, overdrives, etc - the things that draw a little more amperage.
