56 Chrysler Guages Voltage ?
......I have been searching but can't find the answer. Does anyone know what voltage the guages run at in a 56 chrysler 12v system ? I put them in my 49 chev 5 window truck. I bench tested the temp and fuel guages. I used 12 volts for the test and all seemed very good, test period was about 20 minutes and nothing even got warm. I used a universal fuel tank sending unit 30-110 ohm and it shows very accurate in the test. The temp sender was from a early 80's chev truck. I heated the temp sender and the guage went up some but not sure how accurate it is yet, but it looked normal behavior. Amp meter I'm not using with the delco 100 amp alternator. I don't want to fry the guages if they can't take 12-14 volts continuos. I know chrysler products in the 60's used a volt regulator for the dash to run @ 5-6 volt , but I don't know if the 56 guages are suppose to run at 5-6V or are ok @ 12V ? . If anyone knows if 1956 used a volt regulator for the guages or am I safe to use 12-14V ? Thanks for any info.
