PT Will not start at an angle

[woodlandfarms]

OK... I have had this happen 3 times now and am really not sure why this is happening.

If I stop my PT nose down on a 15 or greater degree slope after running it for a while it will not start. In any other position this is a non issue...

In the past I have had to wait a while and it restarted. This time with some perserverence I got it to go after cranking and cranking...

I am going to call Terry tomorrow about this one but wondered if anyone had any ideas.....

Your oil level will be low and running away from the low oil level sensor , it is preventing it from starting .

I have had the same problem when loading on my tilt deck trailer particularly when the machine is hot after a hard work. The last time it did this it would not even crank and was part way up the trailer, backing up. The starter solenoid had broken of its mount and quit functioning, probably from shorting out. I jumped the starter but it would not start until it was rolled back down to the ground. Just what I wanted to do at 9pm after mowing on a hot day, work on the tractor just to get it on the trailer. Anyway I figured it was the oil level causing the problem.

I checked my oil and it is full. Also, this PT is rated at 45 degrees and the engine is supposed to handle slopes like this.

I guess a call to Terry will give me some peace of mind...

Carl,

You might want to check the engine interconnect harness, and the wire connecting to the deutz fuel solenoid. My PT had trouble starting (after cleaning) and ultimately, I traced it to some extra dust in the engine interconnect (and on the deutz starter solenoid). I put on a little contact cleaner, and it starts just fine.

You might also want to check the cable interconnect behind the instrument panel and verify that the wires are tight and that the connections at the PTO switch are good.

All the best,

Peter

There are two additional safety switches in the start circuit--at least on the machines with a cable for the tram control. One is the operator presence switch in the seat. The second is the tram in neutral switch that is located at the tram pedals on machines that have a cable. If either switch is open the machine will not start.

It sounds like the motor is cranking, so I think the two safety switches would not be the problem.

 

[woodlandfarms]

Yeah, engine cranks...

Terry thinks it is a short in the electric that runs the fuel injectors. He told me where the connector is, and I am going to take it apart and clean it.

Why it is slope only is still a mystery and I am not sold this is the solution... Then again, maybe the connection is triggered off on severe slopes.

I am now working much further away from the house than before so the walks back home are a bit of a pain.. Hope we have a solution here...

OK, if it is cranking it has to be a fuel supply problem. The electric fuel cut off valve has to work--that is it must open when power is applied and that is what Terry is suggesting as a likely problem. If that checks out and there is still a problem then start at the tank--is the level sufficiently high that fuel is available on a slope? Is the screen fouled? Is the filter clogged? Is the fuel line clogged? If all of that is good then you are to the injector pump--and since it starts sometimes I think that is unlikely to be the problem.

Find yourself an old Honda Trail 50 and strap it to the engine cover!

Sorry, not productive, but still a fun thought. Kind of like a dinghy on a yacht.

Brilliant Idea !!!!

I would temporarily bypass the low oil sender and see if it starts . The sender only kills the ignition power , the engine will still crank . The sender could be faulty .

It's a diesel...

I meant ignition power to the fuel cut off solenoid .

Being the idiot I am, where would I find this on a Deutz 1011 engine? What should I be looking for. I have wondered if something like this is the issue...

Being the idiot I am. What should I be looking for.

Good to know there's at least two of us.

I'd look for something with a wire attached that's in your fuel system between the fuel tank and where it get squirted into the cylinders.

The electrical path from the key switch goes to the terminal connector board behind the instrument panel and then via the wiring harness through the tunnel back to the terminal connector located in a box on the right hand side of the engine. from the box it then goes to a plug on the left hand side of the engine. From the plug on the engine it goes to the solenoid located on the left hand side of the engine. There is a nice wiring diagram on John Coxon's (Sedgewood) Wiki. While John's diagram is for the 1845 I believe that the 1850 is very similar.

 

[woodlandfarms]

The electrical diagram I have, I was referring to the whatever sensors / fuel pumps and their location on the deutz...

The one funny thing about this is that Terry said next time it happens, just wiggle the wiring harness to see if it fixes the issue. That is not the funny thing, the funny thing is that the lid on the 1850 engine weighs hundred (s) of pounds. The thing is a herniator. Put it on a slope, going downhill. Man am I going to be bent...

Boy is there something hinky with my PT. I am NOT going to dive into this one...

On the electrical chart, it shows a green wire handling fuel control...

Surprise, my green wire is cut. Now it gets interesting. When I change my filter and have to release the air from the pump, I can start the engine with this plug pulled...

Well, this is now a winter project.. When I replace the motor mounts... Not going to try and figure this thing out now...

If the green wire is cut, but you can shut the engine off by turning the key to off, another wire must be operating the fuel control solenoid because it is stopping the flow of fuel that shuts a diesel off. Of course figuring it out may be difficult
