Finally back to it....issues???

If you have the optional indicators, low fuel and low oil, you may want to unplug the low fuel warning module. The 5v IVR voltage goes to this module. DG/W wire #367.
The EVTM says it's "Mounted behind upper RH side of I/P".

I'm sure it has those, since I just replaced the low oil sender (cause it was leaking) Question is why would I want to unplug that, other than dropping the load on the IVR?

In case the module has a gremlin that is screwing with the IVR voltage.

It would cost more, but a DC-DC converter would be more efficient might eliminate the need for the heat sink.

If my math is right, a linear voltage regulator is ~35% efficient going from 14V to 5V. A DC-DC Converter would run between 75-90+% efficient.

So the OE IVR is a mechanical like the MOPAR ones. Makes sense.

I put the car back together today and took it out for a 40 minute drive. I started by letting the motor get to operating temp on a 12 mile jaunt. The temp seemed to be just hunkie dorie. So then I turned the lights on (just the headlights) and continued driving. Eventually the temp red towards the high end of the normal range, but never read as hot as before (basically pegged) and you could see the gauge move up and down with the cycling of the fan and/or thermostat.

At one point, however, the light to show the suspension in "FIRM" went out, and stayed out until I turned the headlights off. Not sure why THAT happened, but it did.

So the bottom line is:
It seems the headlight switch replacement fixed the flashing problem
It also seems it helped (somewhat) with the gauges reading high problem
I still believe the IVR should be replaced (with a digital unit)

I've found TWO places that sell an electronic IVR. One is made to be a direct replacement for the MOPAR O.E. unit (which doesn't have the 9v battery snaps) the other unit is one that could be used on Fords quite easily.

Here are the links:
