LBZ Allison simple question

[Blacky]

Just FYI, the hours are stored in the cluster, so ECM flashing wouldn't cause the hourmeter to reset.

Thanks Cougar I learn something every day. Sometimes (like now) I even learn useful info.

Thanks for the explanation Paul.

Do you know what would cause it to reset?

I've heard of it happening before, but I don't know why.

Ghosts in the machine?

Hi , it is known by GM for a while , according to some GM engineers the IPC has a battery feed and a ignition feed , the difference in voltage between the 2 for a certain amount of time (some milisec) during a crancking event with a set of battery not at 100% recharged on a large block or diesel could create this concern. Basically low battery and high starter motor current draw .

That makes sense. I pulled my second batt around the same time it started. Thanks!
