gauges problem 1966 5 gauge

stanger66 · 04-13-2006, 07:00 PM

Hey guys,

Has anyone had problem gas gauge, temp gauge, oil pressure gauges not working properly. All the needles stay at high or full. They move all the way to one side. I think the alt gauge is working properly it stays in the middle. I have already replaced OPS switch, Temp sensor, fuel sender and still aren't working.

Please help,

ross

Change the IVR and it should be OK.

Hey Gearhead,

Do you know the location of this relay is behind dash?
Thanks

It is attached, usually with one screw to the back of the instrument cluster.

Instrument Voltage Regulator.

IVR actually means instument voltage regulator and it's right where Gearhead says. It's a tiny little silver box with 2 leads going to it.

Ok

I replaced that IVR and its doing the same thing that the old IVR was doing. Do you think if the wires are grounding out would cause the gauge to the full position and the H positions.

Hey guys,

Does anyone know where I can get a wiring diagram for the under dash wiring. I need fiqure out why these gauges arent working properly.
I have checked about 4 different books (chiltons, etc.) no Diagrams.

Thanks

The Ford Shop Manual should have what you need.

Hey gearhead999,

I have one from when I used to work at ford and it only goes back to 78 mustang II.

Do you think their might be something online I can print.

I know that NPD has them in print and on CD.

They also list just the wiring diagram for $5.95. Pretty cheap too.

Sorry, don't know one on the web though. Maybe someone else does.

Hey Gearhead999,

Can you tell me what NPD is. So I can go there to get it.

Thanks

Just so you know, if the gauges aren't COMPLETELY isolated from cluster housing, they'll not operate properly due to grounding out. There is cardboard isolators that are supposed to isolate them and do ok, but I ended up spraying the housing with a nonconductive treatment in order to improve isolation. Long time beating my head against the wall on that one.
