More fun if you lick them first Tango!

All I learned about electricity I learned from grabbing the handle of an un-grounded barn refrigerator and pulling it down upon me because I couldn't let go.

What you call 'electricity' I call a 'necessary evil'.

I’m in the exact same boat ( or bus). I have a 1997 bluebird. I removed all the buzzer and interlock apperatis. I have also removed all heaters and associated wiring. And I removed the warning light “ little yellow box” and intend to remove all the upper lights and thier wiring. It has something to do with my being OCD I think. Anyway the bus will turnover but it will not start. So a question I have is, what happens when the interlock does its job? Does it allow the bus to turn over and not start? I have the same color wires as BrightonD. The orange wire is solely for the buzzers, the red w/ black stripe is for the E-exits safety, and the solid pink is for the ignition interlock. When the system is intact and working do the pink and red wired go to ground and allow the bus to start? Any pointers would be greatly appreciated...

Glad to know someone else is in my boat[emoji2]

Anyone have experience with this rear setup? It got late so I couldn't tinker with it but I plan on clipping and testing the removal in a day or two. Hopefully I can just tie the two coming out of the wall together and call it a day. I'll keep you posted if nobody confirms beforehand.

Update: I just clipped the two wires coming out of the wall and capped each of them off and all was well.

I would make a schematic diagram on paper, then I could tell the sequence of the relay operation for the door switch.
most all that stuff can be ash canned.
On my thomas, there was a wiring diagram for the entire bus on the access panel so all this stuff was quite easy to remove on mine

Could I see that diagram of yours

Brightond - did you ever figure this out? Also have a bluebird and I removed my metal panels, which meant unscrewing my Child-Check system (so not ground) and now bus will crank, but not start. I tried disconnecting the orange and pink wires in the electric box, but didn't help. There is also a red with black stripe wire which I haven't traced. Looks like ground was done at each lock and no running ground wire. Any tips appreciated.

Sorry, just seeing this. No, bus still won't start. I've exhausted my skills and am waiting on my buddy who is more electrical/mechanically inclined to help troubleshoot.

Unlike you I have no crank. All seems dead at the key. Weirdest part is as we were disconnecting the interlock / emergency door wiring we started the bus at every disconnect. Next day it decided to quit.

If you have any insights I'd love to hear them

I disconnected the pink and orange from both sides of the plug in panel (not sure correct name but think you need both sides disconnected) then went to the first or side door connection and just unplugged the red/black wire and it worked. Then I was able to cut it all out and just taped the end of the red/black power line until I can trace that. So my hint would be to check that the pink is unplugged on both sides. Good luck.

I haven't disconnected the ignition interlock, but to disable the buzzers I simply removed the ground from them. That shut them right up!

This is how my 2001 Thomas Freightliner FS 65 (77 Pax) is wired to the emergency doors and windows. Hope this helps.

Thank you that’s great

Update: Bus starts!

Apparently my gear shift was not getting into neutral, therefore no starting. Playing with the gear from reverse to neutral fixed it.

Good news is the electrical drawings BlueBird sent me are accurate and I now have a much better grasp on the whole electrical system.

So, we removed all the door alarms and the bus starting was not affected. Sweet

Could you share your wiring diagrams from bluebird?

[Evey_c]

I wish I would've checked here first. I cut the wires to the left side emergency exit window on my bus to move it and now the bus doesn't start. It was one purple and one white. Any suggestions on how to resolve now?

[EastCoastCB]

try reconnecting them?

[Evey_c]

I ripped most of it out, threw it all away and reinstalled the window. ugh

[gs1949]

I also ripped out all the wiring for the emergency doors and hatches, just threw it in the scrap pile. But my bus is a 1995 model and has no computer chips, so it starts just fine. Now you know you can't get away with doing something like this on a bus with computer chips.

So I think what you need now is either a wiring genius who has some familiarity with your type of bus, or a wiring diagram.

And, hopefully to prevent this from happening to someone else, it would have been best to try starting the bus after cutting the wire, but before removing it. I'm still doing that as a precaution every time I mess with the wiring even though the bus has always started every time so far.
