    I have a 2009 prostar with th isx 450. I just replaced the ac compressor this past thursday and the driver side door handle today. When i got back to my truck this evening i started the truck up and got a "electrical fault" warning. The gauges didnt move, the buzzer never stopped'The tractor and trailer abs lights were on and the engine brake light flashed. Has anyone ever dealt with this issue? Any help would be appriciated.

    The cluster is it's own little computer and might be locked up and needs a reboot. To do this, you need to remove the breaker labeled "BAT" for the cluster. I can't remember exactly which breaker it is, or what they specifically call it, but it should be labeled something like cluster or instruments. There will be two of them, one is "IGN" one is "BAT". The BAT is the one you need to remove to allow it to reset. Pull it out for about a minute with the key OFF. Then reinstall it and see what happens.

    Battery breaker for the cluster should be F2-G, 15 amp.

    No, that might be a locked up body controller. To reset that, you need to disconnect the main batteries for about a minute.

    I just tested all the terminals in the breaker/fuse box. All have power. I ended up taking the truck to the shop and having them diagnose it. Thanks for the help Heavyd.
