Be watchful in that I ordered a sending unit for my SX4 gauge and it read wrong so I ordered another one from another source it also read wrong. I tried one I had here and the dumb thing pegged the gauge when it has pressure because it worked backwards of the other (likely it was from a later Jeep or something)
I have had trouble with sending units from parts stores - they may "fit" but aren't always the correct resistance range. (impedance is not the same as resistance- for the record ) (Also, just a tip for lurkers - sending units are for gauges, oil pressure switches are for lights. Sending units vary resistance with pressure where switches are on or off with nothing in between) |

You just said it - "is used in AC circuits".
I've never seen it used in DC - it's sure not in any book I have used in reference to DC. (some of those being from the 1960s and 70s) So I consider it misused as applied to pure DC circuits where we measure resistance - and the specs we compare to and measure for are in ohms resistance, a straight measurement and part of "ohm's law" formula. ( I know some folks like to repeat what they read and use it as an attempt to show knowledge - so you see it used or misused in such cases as well) |

This is some info on the Miller tool to check the Mopar gauge senders.

The new sending units are junk and never seem to work right.

Have you done any more resistance checks? I'm guessing you should have about 55 ohms at idle (15 psig) and 25 ohms at 2500 rpm (40 psig), or thereabouts. This is based on what I THINK a Javelin oil pressure gauge is scaled at, 0-80 psig.
