Board Moderator & Exner Expert 10K+ Posts: 13066 Location: Southern Sweden - Sturkö island | Most probably you already know this Chuck, but there's a voltage limiter (somewhere? (Chrysler 60 built in to the oilpressure gauge)) that limiter should supply the gauges with approximately 5 volt. If you connect a voltmeter to the lead wire, it will pulsate from 0 to 5 (7) Volt and if you connect a testlamp, it shall flash. If this limiter has gone ape, many strange things may be noted - fuel and temp meter can go up and down together, oilpressure may change up and down. Hypotetically, if your limiter supplies too low voltage, the resistance on the lower part of the sending unit will be to high for to affect the gauge. That's my theory anyway... | ||

Expert 5K+ Posts: 6203 Location: Big pimpin' | Again, the "NEW" sending units do not read correctly....There are ALOT of threads on these things....Try to find a good used one or, you COULD try aftermarket gauge and sender set up for GM style.. | ||

Expert 5K+ Posts: 6203 Location: Big pimpin' | Chuck, you MIGHT try one of the senders off a later model Dodge/Plymouth car and see if it will read correctly...There are at least SOME of these left NOS...I don't know if the OHM rating is the same or not, but if you could try a buddy's while it is out might help you...I know the '65-'70 Sender won't work with the '57-'58 cars, but I don't know bout a '60....You would have to remove the sender part and install it onto your arm and pick-up if it works... | ||

Expert Posts: 2319 Location: Eastern Iowa | Just went through this with my F with the repro A****er Kent tank unit. Would not read any more than 1/4 tank....Ever!! IMHO the repro units look cheap. They have no locating tabs to begin with and the float is nothing more than 2 hardware store corks glued together top to top with the float arm stuck through them and bent so they wont fall off!! The plastic encased "sweep' looks to be of modern design but the rest looks to be stone age!! Dave Schwandt | ||

I have the one from ebay as well.... to get it to work you have to loosen the potentiometer and turn it a little then re-position the stop piece. Have the tank out and hold the sending unit next to it hooked up, turn the key on and watch the gauge as you lift the sending unit float up to the top of the tank level and see what it reads, then make the adjustments. I have mine reading pretty close.... reads 1/8th tank off from E to 1/2.... no big deal there, reads full when the tank is full..... this sending unit is a pain in the ass but you can get it to work. | ||
