Hey guys I have a 1980 Totoya pickup dlx. I bought a sr5 cluster from a junk yard to swap into my truck. When ignition is turned on the tach jumps up to 2.5k and stays there whether running or not. I wired up signal from the ignitor where you are supposed to grab signal and pinned it into the correct pin on the cluster but no difference. So I dove into the cluster to see if anything was wrong and found a burnt resistor on the circuit board, as seen in the pictures. If anyone has a picture of the board on their tach I need to see what band color pattern the resistor is (or the resistor value) so I can solder in a new one. Thank you!

 

Hey each person, i picked up this 81 a pair days ago, astonishingly i only paid $two hundred!!! In any case, it has a few problems, but runs awesome. The one problem i tinkered with all day is the Tachometer...It dosn't paintings... I tried to trace wires to peer if perhaps that was the issue, but i got lost lol. How am i able to test it to look if maybe its just wiring, or if i want to replacce it?

Did you find the info you needed? I've actually got my cluster apart right now and can check on that resistor for you tomorrow. Which resistor is it?
