speedometer rpm tach and gas gauge

***doberman 152*** · 04-07-2018, 09:16 AM

So i had to put a new battery in the SS now the speedometer is pegged on 150 and the rpm tach and gas gauge don't work. My question is do i have reset the PCM, or disconnect the battery for 10 mins.

I would disconnect the battery for 10 min.

I did all of my above, the disconnect of the battery first then the pcm, still nothing i think something is grounding out. Maybe over the winter storage there was some moister in the clusters, i'll keep chasing it.

hope no furry little friends didn't chew on some wiring.

It does sound like a ground issue. Electrical is ALWAYS a MAJOR PITA to troubleshoot!!

Thats the first thing i thought, but when i took it down the road for a quick blast i put my right tun signal on and it came on but didnt blink, the left one blinks though so hmmmmmmmm

no, no diagram

Have you checked the charging voltage? Low voltage will sometimes make things act screwy.

***doberman 152*** · 04-12-2018, 12:22 PM

got home from work and did the voltage check everything's good, so i think im just gonna run it to see if it comes into it if not maybe moister got into it and i'll just change out the cluster (last resort). So if i change out the cluster im gonna buy the white face SS cover for the cluster i always liked that so maybe its a win win dunno.
