The Stovebolt Site Forums The Shop Area The Electrical Bay fuel gauge voltage reducer

Have 1953 3100 converted to 12 volt. Still using 6 volt fuel gauge. Installing votage reducer between gauge and ignition switch. The reducer is just a little ceramic block with a tiny wire with no insulation coming out of each end. What is the proper way to connect this in line? Just twist wires together and use heat seal or what? Thanks

You should pick up a crimp-on wiring kit that comes with proper 'ends' and usually the crimping tool, found at most auto parts stores. But there is a better item to protect your gas gauge. Search Chevs of the 40s or Jim Carter's for this voltage reducer.
Best of luck

RUNTZ VOLATAGE REDUCER INSTRUCTIONS !!!!!!!!!! Choose the second link for the download.

Someone else will probably answer this for you before I can get out to the shop and look at the instructions that came with one I bought from JimCarters. I'll check tomorrow night! I sure don't want to quote it from my memory!!!

From whom did you buy the reducer and what is the part number?

Jim Carter #EL 110. Thanks

Tim, I got it from JimCarter. Part # EL311 Runtz. I ended up not using it as I had my guage changed to 12 volt...but I have one if me or a stovebolter ever needs it!!!
Oh, the price was $18.50 minus 10% left $16.65

Did you see my link ?Its JIM Carter's instructions !

Is Jim Carter's EL110 and/or EL311 a Runtz reducer?

webstershotrods,

Which link is the instructions you are referring to? The .doc file from fifthavenueinternetgarage.com? If that works with a Jim Carter part, which part number?

The part # EL3110 ABOVE SHOULD BE #EL311. That's the one also for the instructions stated above. Since you have the same part number EL311 for sale the instructions are the same that I gave a link to? Jim Carter Must get the RUNTZ from the same supplier as FIFTH AVE? EL110 is a smaller reducer that Jim CARTER doesn't recommend using? Just what they said when I ordered mine! Sorry I didn't post the part number it's in the instructions also.

Paul, I have a restored '36 Chevy pickup. before I restored it I ran it for about 50,000 miles as a sbc powered rat rod with a 12 volt electrical system. The stock gas gauge and sender worked perfectly on 12 volts with no voltage reducer required. The gauge has opposing coils that pull the needle towards the coil that gets the most current so 12 vs 6 volts made no difference. If your gauge is the same all you need to change is the light bulb.

To me part of the fun of this hobby is finding the most cost effective way to get the job done. I hope this helps.

Thanks everyone, I think I'll try the Runtz product for my application. The ceramic one will sit on the shelf. Cheaper isn't always better, I should have bounced it off you folks first!

My experience was very much like Yar's. I've converted one vehicle from 6v to 12v and didn't put a resistor on the fuel gauge. I never thought about needing to do that. I put over 100K on the truck after the conversion & never had an issue with the fuel gauge.
