another cluster question
I have a 84 with a black dash cluster the turn signals work. I looked on batee.com about a fix. I would like to start with the ground wire. I have one that goes to the block on the drivers side below the head and then to the frame rail by the battery. That one also goes to the neg on the battery. Is that the one they talk about on the batee web site? Where does the ground wire for the dash cluster come out of the firewall at?
Help Please!

You are missing the point. There may be one ground wire in the Harness......but Batee is talking about the green PCB board inside the cluster.....that PCB has components soldered to it. That solder is old and it has cracked, creating a short....
Your job is to take the cluster out, take the three boards apart and then using a soldering iron, heat up the old cracked solder and make it flow again thereby re-connecting all the components to the green board.

Besides the ground strap that runs from the stud on the head to the frame, there is a ground wire that comes from the loom that attaches to the bottom transmission bolt on the drivers side. Loosen it up a little, wiggle it back and forth to make sure it is making a good connection. That is a bad spot that catches a bunch of road grime, leaking oil, etc.
You should locate the three ground wires at the cluster connectors(look in your factory service manual to find which ones they are), splice a new wire to each and run them to a good ground(I ran mine out to the ground strap on the frame).
Also, you didn't say anything about looking at your power supply board in the cluster. Check the small strip of wires that connect it to the main PC board. Mine had one wire that was broken. You also need to hit the larger components of the power supply with the soldering iron. Those pieces take a lot of stress and are not very secure to the board for being in a car that rides as rough as these.
