All dash instruments reading low
 
Like the title says all the dash gauges are reading low. Temp at 1/4 when hot, fuel at 3/4 when full and so on. The gauges all work just reading low.
Its an 09 H3T alpha, really like the V8.
Power issue or blown transistor? Any help is appreciated

Thanx

Jim

Check battery voltage: 12.5v resting & 14.5v charging.

Reads 12.5 resting (off) and 15.5 after start. After running for a few min reads 15.0
We have driven it for about 4 months, nothing seems to be wrong with the charging system.

When I had a similar problem in my H2, the stepper motors in the cluster needed to be replaced. It may be time to get your cluster refurbished since the truck is now a decade old. Do u have any other symptoms like a dim display or bulbs out?

You still using the Crappy OEM Battery Terminal Connectors?

The previous owner replaced all the cluster bulbs with LED's and they are a little dim. Looks like I need to take it out and just see whats what with it.
