Weird Turn Signal/Backup Alarm Issue!!!

A recent purchase, my 1989 Chevy p3o short bus is in tip top shape. Except for one problem. First of all, the runners, headlights/brights and brake lights work. The problem occurred when I was doing a light check and found that the turn signals were not signaling. Thinking that this was a routine fuse, connection, or bulb issue, I started with the fuse panel. AHA! I said...A burnt 15 turn signal/backup fuse, an easy fix. I replaced the fuse and started the engine. Immediately, the backup alarm came on despite the bus being in park and remained on in drive as well. In addition, the engine seemed to be throttling higher or possibly the starter is engaging unnecessarily after starting. When I removed the new fuse the engine ran normally and the backup alarm and turn signals did not work (obviously). Any thoughts? Crossed Wires?

Do you have a wheelchair lift? There might be something up with that. I know they tie into the parking brake for safety and sometimes are driven by a pto. So that would explain why the engine starting idling higher because the pto might require it. And putting that fuse back in might have put the whole (possibly malfunctioning) system back into operation.

That's about all I can think, or perhaps you got some wonky wiring.
