Unhappy Removed Wheel Chair Lift NO START!!!

So I removed the wheelchair lift out of my 1994 Blue Bird TC2000 and now the bus won't start. It cranks but won't turn over. Has anyone had this problem? What do I do?

First, please fill-in your profile so we know what you are driving, as the fix is different for each make and model and year.

Close the door and latch?

oh, and Welcome.

Welcome ... It's been a few days since we have had an interlock issue

I followed the wire and it goes into the dash. From what I heard I need to pull a relay but I have not idea which one...

Usually they are grounded by the screws attaching them to the frame.

When you removed the assembly, you removed the ground.

You know, the easiest way to deal with that is to put back the door pieces you removed. It doesn't deal with the interlock issue but it does let your bus run until you're studied up on the interlock and how to disconnect it at a later date.

Here's a video. It may not apply to your specific bus, but may be helpful.

Congratulations! You're going to become somewhat of an expert on the interlock system on your particular bus.

It's not uncommon for interlock issues to pop up two or three times a week on this site. As you can see it happens quite innocently. This is like the Monopoly "Go to Jail and do not collect $200" card. The problem is even two buses of the same model and year will often have dissimilar wiring of the interlock system. Just to make it fun I guess. They're all similar in theory, but usually have subtle wiring differences so it's not easy to instruct someone about how to fix it. It's not that hard, but it's definitely a learning experience.

I had an interlock issue on my rear emergency door. Funny thing is it even had a little sign on the door identifying it as an interlock door.

Yet after I disconnected and couldn't start the bus, I freaked out for about two hours. Lessons hard learned never go away. I fixed it by replacing the parts that I had removed. I understand that you aren't able to do that at this point.

The only difference that I can tell between your situation and mine is that when I attempted to start the bus I only got a loud clunking sound from the control panel to the left of the driver's seat.

The motor didn't engage at all.

You may have more going on then just an interlock, but lord knows I'm no expert.

Also, an interlock is usually just a pressure switch that closes a circuit. Potentially, if you could track down the wires that were connected to the interlock and connect them together, it should bypass the system until you can lock down the specific relay to remove.

Interestingly, I also have a wheelchair lift but it does not have an interlock at all. It's on the side door and I have already disconnected the wiring to it.
