There has to be a way to put your transmission into neutral. It may not be marked, but your transmission has a neutral. The neutral safety switch is on the transmission itself, not the shifter.

Not sure what you mean by quick release blocks??

The neutral switch can be inside the shift tower there are lots of those around I keep the switch in stock for the shift towers

Didn't know that. For the V730 or just the 4-speed?

If your looking at all the wiring on the back of the engine bay, there are 2 small blocks and 1 large block with wires attached. The blocks split in half with half the block staying  attached to the firewall and the other half with the wires connected pulling free. I would post a picture if my camera wasn't broken.

PM sent with my phone number. I've got the manual in front of me - I'm happy to help you figure out the wiring if you want to call.

If he has a Stone/Bennet shifter he probably shut it down in gear, when that happens you get nothing till you manually put the transmission in neutral

That sounds familiar. Panic sure sets in fast the first time that happens.

Sounds like you are looking at the "Regulator and Apparatus Panel". All those terminal blocks should be mounted to the firewall. I'll post a photo of this from the manual. I don't think this is where your problem is though. The controls for the starting circuit are in the "Engine Bay Apparatus Panel", which I posted a photo of earlier. It's likely got an aluminum cover on it and is located on the upper firewall above the engine.

At least on my V730, the neutral safety switch is inside the transmission. I know this since my cable shifter has some play in it and it can indicate neutral, but still in gear. Solution-always make sure it is in neutral before shutting down the engine. Good Luck, TomC

Try holding down crank switch while moving shift handle a touch back and forth.

I just got into this thread and realized your only about 40 miles from me. Let me know if you need a place to stay and if you were able to get the bus running. I'm not a mechanic, but I have had several buses and have gone through a myriad of similar issues. I would love to help in any way I can. Please don't hesitate to let me know. Glennman.

Thank you for the kind offer Glennman, at this time I'm not sure what I'm going to do. I am flying into Yakima this morning and am hoping to find a shuttle down to the bus in Grandview. I'm planning on staying there till its fixed. If you have or know anyone that has repair manuals for the 4107 and or 8v71T in digital format that would be an awesome start! If you feel like working on a really cool bus in sub freezing temps you're welcome to tag along! haha

What type of shifter do you have for your V730?

A toggle switch or a shift lever?
