Some plastic polish, I used some from a headlight restore kit

I put it in my truck today and everything functions besides the speedometer and the tach. Anyone had this issue or knows a solution?

i have the same and my speedo is off by 10mph and at highway speeds its off 15-20mph as well as my tach i hook a scan tool and see the rpms and the cluster shows a higher rpm than it actually is. Any ideas

Just an update for anyone who responded to this message. I got the cluster broken down this morning. The plastic gears seeemed fine so i dialed odometer back and reseated connections. Alternator is currently out of my truck but plan on one day this week getting the new pulley in and taking it for a 20-30 mile ride to see if the problem followed to my truck and milage tracks or if it was tylers truck.

Well. Back to sqyare one. Followed vehicle to mine. Took it for 9 mile drive. Tach, speedo, or odometer ever moved. Got to be something internally in the cluster. Only thing shared will be ground. Circuit 121 tach is its own wire. Circuit 824 vss its own. The (2) 39 power circuits that send voltage to everything else works. Anyone have a drawing of cluster or knows what else they share? I dont see any resistors for that circuit. Only the 25 gen / alt has one.

If the odometer motor went out; would that have any affect on itnand the speedo not spinnning? Tho very uncommon ; i have seen these go out before

 

[jus10inbrla]

Well. That myth is debunked. Had spare motor from a empty cluster. Nothin changed. @tybcr783 ; where did this cluster come from originaly ? Ebay ? Craigslis / marketplace?

Found it in a Yukon Denali at a local pic and pull, could the issues be on the rear contacts where it actually connects to the truck?

 

[jus10inbrla]

No. Those contacts were good when i ohm out
