Temp reads low on factory guage and 185� on my Autometer mechanical guage. I also think the fuel guage reads low. What can I do to correct the factory guages. Would it be the voltage limiter? Where can I get a solid state unit? This is on my 1978 Ramcharger. Ask me my opinion of Frank Mitchell....... A Mopar crook!

Some had a seperate wire that grounded on one of the dimmer switch screws. The ground is good, a lead goes directly to the firewall. I will try a different limiter. Who converts these or sells solidstate ones? Ask me my opinion of Frank Mitchell....... A Mopar crook!

I always run a separate grounding harness for everything straight to the negative terminal of the battery. It's a pain, but it works! Also, the factory gauges were never intended to be accurate, they were there really to show that a system was functioning.
