    How to calibrate speedo?

    I didn't know they would go all the way around. I read through that write up and I think I'll just get new gauges. My speedo was the only one that worked in the first place anyway. I very much appreciate the info though. Who knows. May hlep in the future anyway

    How to calibrate speedo?

    Mine is a ribbon gauge. I think that's what it's called. Just a white bar that goes from one side to the other. But it isn't like any of my other gauges work anyway so I am reluctant to put too much time and money into the speedo.

    How to calibrate speedo?

    OK. Thanks guys. I will read through and make a decision. A speedo that goes higher than 80 may be nice... But thanks. That aughta do it

    How to calibrate speedo?

    Oh OK. I guess I overlooked that. Cool. I'll look into doing that. I've had the cluster out before. But only unplugged from the little plug in back. Am I right in understanding it as actually physically breaking off the pins that need removed? Like clip them off with some snips maybe?

    How to calibrate speedo?

    Hey guys. Probably a bit of a silly question. But I can't find good info for it. So I have looked around and found some stuff on calibrating a speedometer for a truck with an auto. But my 89 has a stick. The hm290 I believe. The truck had 3.08 gears but I changed them to 3.73 gears because all...

    Gauges all read incorrectly and vary with signal

    Oh also there's no ground direct from the battery. That's been cut. And there's no ground I have found yet on the engine either.

    Well fellas I may just leave it all. The truck runs fine. Somehow. The ground for the gauge cluster has been cut, the ground on the firewall under the heater hoses isn't there, and the ground on the passenger side of the frame that it goes to also doesn't exist. A ground for something is wrapped...

    Gauges all read incorrectly and vary with signal

    I think 30-40psi oil pressure is probably normal. Which is what it reads. So if it's just a bad ground that's an easy fix and I'll happily do it. I know my temp gauge is incorrect. I'd like that to be considered rrect for safety reasons. Don't really wanna have to fix a head gasket or worse. And...

    Gauges all read incorrectly and vary with signal

    I know it's dark. The little silver piece on the top right corner of the connector is a bolt on Terminal that has been cut. I'll have to trace the ground from B the cluster and fine where it had been moved to

    Yeah. The tab is there. Nothing is connected to it. The wire was cut at some point and moved

    Gauges all read incorrectly and vary with signal

    OK well I will let yall know if that is the issue. There is a connecter for a wire that is bolted onto the right side of the obd port but it has been cut. Idk where it is now. There is a massive rats nest of jumbled up wiring underneath the dash. Whoever had the truck before me I have already...

    Is the ground connected with a screw tab onto the obd port bracket?

    Gauges all read incorrectly and vary with signal

    Oh I forgot to tell yall truck info. I apologize. I have an 89 swb with a 350 tbi and a 5 speed. And I will go check the ground right now

    Gauges all read incorrectly and vary with signal

    I can't be sure of course, which is why I am asking the question. But I don't think the issue is the cluster. I think it has to do with wiring. But idk where to start looking.
