View Full Version : 12 volt conversions for R-series trucks?
07-23-2002, 07:11 AM
Anybody aware of pre-packaged 12 volt conversions for R-series trucks? I am debating whether to go 12 volt or stay at 6V on my completely original 1953 R-112. My biggest concern is getting a tach hooked up but if I can find a 6V to 12V converter I might still be OK. Any original tachs available for these? Are they mechanical or electrical?
I also would love to be able to pull trailers around so 12V may be the only way to go. I reckon I will also need info on how to convert the 6V gauges to work on 12V.
Any help appreciated.
My R-190 is a (assumed) factory 12v w/ a positve ground. Now does your's have a positive ground? if it does then you can just swap over the voltage regulator and generator from a a truck with the 12v system. I wouldn't think that the gauges would be affected by the diffence in voltage but don't quote me on that. If it is a problem then just pull some 12v gauges out of a donar truck. If you have a negative ground, there is a kit out there to fit Delco alternators on IH engines (voltage regulator built in). Hope this helps

I'm pretty sure 6volt guages don't like 12 volts feeds.... back to hiding...

Sucks! 6v original is sweet...so nice to be "Policitaly Correct"
but..the 12 volt change over will save you $$$ and time.
Not to mention the infinate posabilities of options....Where are you going to get a 6v battery? how are you going to charge 6.9 amps positive ground with the radio running ?
Give Gordy an e-mail..set you up sweet...that thing is in need of juice..............much advice.............i.e. scrap yard goodies!
