While looking for the no start we did find the engine wiring harness was routed under the air compressor discharge hose on top of the air compressor creating a abrasion point. On this vehicle the plastic loom was burnt through. None of the wiring appeared to be damaged but quite frankly none of us could get our faces close enough to see the harness very well.

It may be wise to inspect any buses in your fleet and make sure this is not an issue on any of them. I believe this will only apply to C2's with the MBE906 engine.

Another thing we discovered, these buses have two steel coolant tubes that wrap around the right firewall and end near the bellhousing where rubber hoses attach with spring clamps. On our bus, we had cold soak coolant leaks presenting at the hose/tube connection. We have yet to figure out how we are going to replace the spring clamps. Like so much on this bus, we can see it, we just can't touch it.
