does anyone rebuild and convert clusters? its for a 1949 ford and im turning it 12 volt and the clusters not working also? thanks for info
If you're talking about the gauges here's what I did. Go to junkyard, find a Ford 70's truck(12 V) and get the gauges and senders(oil & water temp). Remove the gauge movements from the cases(plastic probably). Install those movements in the cases of your 6V movements. install the senders and wire up. You'll find that the 12V 70's gauge movements are identical to the early 6V movements. I did this trick on my 41 Ford 10 yrs ago and it worked like a charm.
LOL, no dont do that,, 70s fords still used 6v gauges. Theres a small voltage drop/regulator bolted to the back of the 70s unit, get that instead, and use it to to powerup your stock cluster.
ford had 6v gauges clear into the 80s, cars and trucks. not much tech needed, get teh voltage regulator, put 12 volts to the hot side, hook the other side to your gauges. you should try to find one at the junkyard though they are kinda proud of those things at the parts stores.
That would be an "instrument cluster voltage regulator". A quick search on the net will bring up a lot of info and links.
I forgot. get the reducers that go with the gauges. they're attached to the rear of the panel. 6V gauges use a reducer to about 4-5 V. 12V gauges run on 6-8V.
