Hi you all,.

We are having a problem with a 2002 Amtran/International, 71 pas. bus.
This bus had, at one time, a rear emergency door lock. I say that because there is a tag on the bulkhead above the drivers seat. The tag says that "this bus will not start if the rear door is locked", and there currently is no lock on the door.
The problem we are having is that sometimes the engine will not crank when attempting to start. There are a number of things that can cause a failure to crank. but I am wondering if, when the rear door lock was removed that it was not done correctly and the circuit that causes the engine not to start somehow gets activated.
Is there anyone of you guys out there that has had some experience with this type of door lock and can shed some light on where to look for a solution to this problem?
Thanks, Jim Loiselle

If the bus chassis is a 3800 there is likely a terminal strip down near the drivers left foot where the chassis and bus body wiring were connected together. There may be connections there that are labeled unplug this connector and connect starter interlock here or similar.

Why yes, the ORIGinal CHARGER is a Fastback

The 3800 International school bus chassis used a variety of engines over the years including the T444E.

Our bus has few markings. It could be a 3800.
We will check for the interlock connector.
Thanks again!
