Thread: Amazing Discovery about Ford F1 Gauges.

Tweet

I'm surfing the internet this morning and came across this topic. The guages in my 51 Ford are not hooked up because I went 12 volts with the hipo 289 transplant.

I'll get a CV regulator today from the junkyard.

Thank you for the tip.

I;m finishing up wiring a customers 55 ford f100, used the ford cvr and it worked fine,other than the gauges reading backwards " I presume thats because it was a positive ground 6 volt system ?? " simply removed the gauges and blacked them out & re lettered... The crv works much like a signal flasher and you can see an ever so slight tick in the needles.

In my 48 Chevy pickup, I used all the guages but one on the 12 volts without a problem. The guages are in a box where they have been for ten years so I can't remember exactly what was what. But the fuel guage for sure worked on 12v the Oil was mechanical, the amp guage worked, (just didn't go as high as with the 6V) and the water temp was replaced with a S-W INSIDE the original cluster. It did go backwards because the thing was up side down in the cluster. But I just remembered that and it never bothered me.
