Thanks ive never soldered anything in my life ive brazed thousands of times as a hvac tech if i ruin the board are they available ? And if so what are they called how do i order one. Can someone else chime in aswell i am very hesitant to cut things being i literally just bought this car. Its for my wife i always told her id buy her a vette.... Also im in canada so whatever you pay times that by ten its ******* great living up north
Soldering electronics isn't difficult, but you might want to practice on something other than your cluster board - especially when doing it for the first time!
Again... Under the circumstances, I can't think of a reason not to send the cluster off to BATEE.

Then I would suggest you send it off to BATEE and let them swap the resistor "chip" for a new one and be done with it.

This is my first ever post. The '91 I just bought has this problem. at idle, the tach reads 2k rpm, and between 2 and 3k rpms its pegged at 6k rpms.
I think the easiest fix is to desolder pins 4 and 11, clip and remove the pins, then solder in a 300k resistor from the bottom of the board into the holes for pins 4 and 11. this seems like a more secure fix than surface soldering the resistor. Is a 1/4 watt good?
