We have a 2008 bus that has the check battery light on (Batteries are new) and the voltmeter gauge will jump all over the place once in a while and when it does you cant shut the bus off if you turn it off it will stay running. Once you get it to calm down (by waiting) you can turn off the bus and start it like normal
Checked the wires, And they all checked out good when the bus is messing up and reading six volts on the dash if i disconnect the battery it dies.....Just had the alternator rebuild to the tune of 450 but am starting to wonder if it is the Alternator
Try another ignition switch the cheap ones they install are often worn out early on in life. When your volt gauge jumps around do other things malfunction? Do you have access to service link through freightliner?
Ground at the battery? It was just wierd that the place we took it to said they needed to rebuild the alternator and then after they was done it is no better
The alternator place made their money...if it didn't work...they won't care. I'm with JustinB...go clean your grounds. Battery, chassis, body, the whole nine yards. Don't forget over to the left of the driver seat, down in the console. Down home they had a C2 that refused to shut off, was a loose ground over there.
There is also a service bulliten on running a new ground wire from the stud above the drivers shoulder to the ground stud on the power distribution modual under the switch panel next to the switch hub modual. It calls for a 8 ga. wire

We had the same problem on one or two of our c2's. The first one ended up being a diode on the leece neville alternator, and the second was a loose ground on the fire wall under the driers area under the bulkhead module.

That is the one most likely to deal with the gauge pack.
I may not know the answer but I can usually find who does.
