nightmare 2nd gen cluster
Hello I just registered. I know nothing about the Ram 1500 line of trucks. I need my head examined for buying something I know zilch about! I have a 99 Ram15004X4 with a little over 100k. When I bought it the alternator wasn't charging. I bought a new computer and that didn't resolve it. I then had a mechanic install an external voltage regulator. I would've done that myself,but I'm recovering from hand/wrist surgery. The cluster is crazy. Tach and speedometer jump back and forth. The odometer flashes. If I engage the parking brake the needles fall and the odometer stops flashing. I bought another cluster and it does the same thing. Any help would be appreciated.

You have a bad connection somewhere.... or a bad ground, or both..... You can download the factory service manual for your truck from here. It makes working on the electrical MUCH easier.
Did the external regulator solve your charging issues? If it did, your replacement PCM also has an issue. Unfortunately, its an all to common failure. Still don't understand why Dodge put the regulator in the PCM..... Just seems like a bad idea to me.
Going to move this to the Second Gen Ram section for ya. Welcome to DF!

Shouldn't smoke the cluster....... and since you have two that are doing the same thing, gotta be an issue with the truck somewhere. On the 99, everything on the cluster is driven by the PCM on the Data bus. (pcm tells the gauges what to to.) So, if they are all freaking out, likely a poor connection on the communications bus. Check the connectors at the back of the cluster. Also check cluster grounds.
