I finally got around to figuring out why my oil light doesn't light up when the key is on. I looked up under the dash and it looks like a piece of the circuit board is broken off around the oil light. the green ends and turns brown all around the light. Am I correct in assuming that I have to replace the entire circuit board to fix this? Its not that big a deal because I have aftermarket gauges, but does anyone know the oil pressure that would turn on the light? I'll probably just mark them on my aftermarket gauge.

Well, that would require a new curcuit board. But I am guessing the PO disconnected the dash oil light anyways. He probably unhooked the factory wire and removed the Ford oil pressure sender to install the mechanical gauge. Look end see if I am right or PO tee d the two senders together.

It's low around 8-12 psi on idle. I carry remember exactly. But that's pretty standard.

Well the PO t'd the temperature senders so I wouldn't be surprised if he did the same with the oil gauge. I will check this evening.

You'll need another curcuit board then. I'm sure the rest of the old one is ready to fall apart. I am sure NumberDummy will chime in soon and give you the part number and places to buy it.

I'm probably looking for just the circuit board unless you still have any of those fancy gauge clusters from the larger trucks you were showing off in your build thread.

No F500-700 clusters for sale.

I do have a bunch of F100 clusters for parts though that I'm not going to use.

How much would it cost to get one of those to the Corvallis area?
