XL rear electrical panel door
Most of you will be fimiliar with the rivit failure between the rear electrical panel and bulk head mounting brackets. Well yesterday I opened the door on my rear panel and the door fell off in my hands. The door hinge is fastened with the same type of rivits as the mounting brackets and these go away as well the fix is pretty easy you can replace the rivits or replace them with machine screws which is what I did. It was good this happened with the bus sitting in the shop.

George, you may recall I gave away a significant number of brackets (angles) for folks to attach to their electrical boxes to better secure them to the bulkhead to which the box is attached.
You are right in that the same type rivets are used to fasten the door. I have replaced mine once already and I find that an occasional drop of oil on the hinge and the rivets is enough to at least slow down the corrosion that causes their failure. For those who have not yet had the pleasure of finding your rear electric box or door laying on the engine
or more precisely the air intake pipe you need to check both the door and the box itself for security.If the box attachement rivets fail the box drops onto the pipe. If the 12 and 24 volt posts are not insulated, they hit the pipe resulting in a dead short to ground and at best the bus quits running. The door, should it fall has the potential to get tangled up in the belts.
The photo above shows where the box separates from the bulkhead. The rivets fail. You can see the remains of the rivets in the holes. They are hollow pop-rivets.
