Bought this 8 years ago. At the time I was in a hurry to get in running and had a kid kind a go through it for me and he did a nice job. It runs well except for the dreaded exhaust leak on the passenger side. Had tranny rebuilt and now I'm trying to tinker with it and fix minor things. I'm not very mechanical but I'm doing ok so far. Got washer pump working, dome light working, replaced float on sending unit, that kind of stuff. Now..... My gauges have never worked and in reading most people say it's the instrument panel voltage regulator. I finally pulled the cluster and noticed that there was no voltage regulator on it. The two wires that would plug into the voltage regulator were plugged into each other. When hooked up like that both temp and oil pressure gauges will peg all the way to the right. So I'm thinking yeah, I need a IPVR. Ordered one from Dennis Carpenter. Got it yesterday and installed it. Little disclaimer in package, make sure the IPVR is grounded good or it will heat up and cause gauges to read incorrectly. Well, unfortunately with the IPVR installed neither gauge moves and the IPVR gets Hot!!! I've pulled wires off the oil sending unit and the temp sending unit and hooked a jumper to them and the gauges kind of move about half way and stop. The oil sending unit is brand new so I would think it's good. I have checked the ground from block to firewall and cleaned it up. What am I missing here? What would be causing the IPVR to get hot? Is there another ground somewhere I should be checking?????
You might edit the title of your thread here to resemble the problem you are having. It will draw more people in that know and can help as opposed to the very general title you have.

There's more than one ICVR, are you sure you bought the correct one?
C6DZ-10804-A .. ICVR - Instrument Cluster Voltage Regulator (Motorcraft GR-510) / Obsolete ~ Available NOS; from auto parts stores & repro parts sellers.
Did you get the correct oil sender as their two types one for gauges aaaa7 one for the oil light. Gas gauge, I'd remove and put an ohm meter on it and slowly move the float arm up & down looking for areas of open no reading on the meter as the sender have always had issues with not reading the full scale correctly.
That cluster should have had a good ground at mostly all metal frame. I think the ICVR was double grounded.

This is what the heat shields gasket look like. this is what Ford only used.
your loco auto zone can order them like most any parts store.
If it's leaking then possibly it was run to long leaking and has burned out the matting surface on the head itself. Only good long lasting fix is remove the heads and get the exh side shaved enough to not leak. So if burnt so badly they must be welded then shaved again.
Check header pipe at the exh flange donut and replace with steel ones.
aside from making sure you have the right regulator.
do u by chance have a buddy with a guage cluster with harness and colt regulator? that's what I did. I swopped to the f600 gauges and they didn't work so I swopped my orginal harness and VR from my old cluster onto my f600 cluster and bam! everything worked.
my point is before u go buying new parts id make sure its not just your cluster/harness.
When you say how did I ground my voltage regulator I'm assuming you mean the Instrument Panel Voltage regulator. It's grounded by the screw that comes on it that you screw into the back of the panel??
I know it's a PITA, but could you take the instrument panel out and post a picture of the back side so we could see the IVR and how your wiring is connected? You can see the IVR in Orich's lower picture, it's on the far right side.
Sure, I've had it out before. I'll do that later this week and post a pic. I'm thinking that when I took it out the first time, the two wires that are supposed to plugged into the regulator were plugged into each other and there was no voltage regulator that the gauges might be fried?? Since there was no regulator in there they would have been getting to much voltage?
