Hey all, Will new 12v aftermarket oil press/ water temp. gauges work in a 6v pos. ground car? Assuming that I’m using the supplied senders, and knowing that the bulbs will be dim to ineffective, aren’t I just reading resistance? What about mechanical gauges? Thanks!
Use mechanical gauges. The kind that use a normal bulb, so you can swap in a 6v to replace the 12v bulb. Or get the original gauges working....that's the most fun approach...
Several 6 volt oil pressure gauges, both electric and mechanical. https://www.kaiserwillys.com/produc...-or-24-volt-fits-41-66-cj-2a-3a-3b-m38-m38a1/ https://www.tractorsupply.com/tsc/p...KD_w58Ms6chz_1pn866fwsbdjPvThyGxoCTY0QAvD_BwE https://www.jensales.com/products/f...4ygm7970L681PGVYCTDZnlONACNboBPhoCK-QQAvD_BwE But, as suggested above, it may be just as easy to install mechanical gauges for water temperature and oil pressure.
