It started with the speedometer. My needle wandered all over the face and jumped around. So, I removed the cable and lubed the inner.
Then, there was nothing. It just sat at Zero. So, I disconnected the lower end, and made sure it was engaged, and it went back to wobble mode.. So, I bought a new cable, of the same size, that was 1” longer. I now had a speedometer that sat still, but, I lost my left turn signal indicator on the dash. Outside, the lights were still flashing. OK
I tried to grab the bulb from below, like the factory shop manual said. I could not get it out. Still no signal on the dash.
Then, the aftermarket Sun 2 tach went out.
Looked underneath and the wire had pulled out of the fuse box. Tach is back, but it went out again. Finally I noticed that the tach wire was being pulled out by pushing the clutch. Rerouted the wire and the tach is back.
Next day, the turn signal indicator started working! I did not change the bulb. Weird.
Tach working, turn signals working. Only thing on truck not working (not bad for a 43 year old truck) is the back up lights, because my 3 on tree truck was converted to a hurst indy floor shifter. I looked for the wires to the back up switch under the truck. None to be found. Two member of this here Fo-Rum reminded me of the switch location is on the column inside the firewall. (right by my tack wires!), So I grabbed those wires and ran them to a lit switch, which I put in the dash near the wiper switch. Throw the switch and back up lights come on. While the dash was out, I reached up to the RIGHT side of the dash and removed one other dash light that has been out since I bought the truck 4 years ago. The bulb looked good, but when I powered the socket, no light. Huh. Took the bulb out and cleaned the socket. Tried it again and let there be light!. Put it back in the dash and reassembled.
Last night I went out after dark, and all dash lights now work!
I think I now have everything in the truck working.. Tach, Speedo, turn signals, dash lights, back up lights.
Shh. Don’t tell anyone.
