Temp gauge would sometimes not read and/ or after a complete warm up the needle would sometimes get just up into the gauge.

The needle pegged when wire grounded; and replaced the sender with a good one - no dif.

As the temp-compensator board usually causes the needle to peg and then drop, I believed it was a bad connection.

1) Connections at the grey block on the firewall were fine.

2) pulled the cluster, removed the board, cleaned the 4 pins. One of the pins was tilted before I cleaned so I think someone had the comp board out and pushed the pin aside - rather than in the little metal tube.

Net, it's fine now. I know the boards go but I've had good luck cleaning the board contacts. And this is echoed in a couple of archive threads.
