Scratch that, we figured it out, I appreciate everything Scott_

Hey Scott_

Same truck had a different problem yesterday. I labeled the post "No Crank, No Start" if you have time let me know what you think.

Ok, well I do appreciate everything! if it comes back i'll let you know what I find in the future.

It is possible that the computer was seeing a overheating condition in what they call step one that would go into limp mode and after it sits or is restarted would go away but with no check engine light only guess see if problem goes away hope l was some help.

Hey Thank you the water was low about half a gallon on the truck., but no leaks, I'll keep an eye on it. Oil didn't look contaminated either, I'll just have to keep watching it.

Can you tell me which way the water flows in the regulator? while mounted on the forktruck is it from left to right?

Thank you fore the very detailed instructions!

First make sure you are getting water to it and there is no blockage in the hoses and pipes it needs hot water to flow to keep it from freezing up make sure your rad is full and the motor is not aaoverheating and has flow to block first before you by a converter it is a Nikki converter and they are not cheap also check the pressure at top there is a plug looks like has a Phillips screw driver slot of you must remove and install gauge it should get 5psi when running and cranking could see more with key on but should be about 5psi running.also make sure there is no air in block there is a Small l believe 10mm bolt at water pump open it up and make sure you have water and no air if rad low could have air in block

I may have found the problem, my regulator is freezing up. Is this a rebuild or purchase a new one kind of thing?

Thank you!

Pull the floorboards on the left side near the fuse boxes the connecter has a dust cover over it it is a small square connector it only uses four wires after you pull the dust cover it is a female connecter a male cable fits in then on the other end is the obd 2 connector to go to the scanner

can you tell me where to locate it? I haven't seen it, and I may have a connector i have a few different ones.

There is a place to connect to but it is a special cable a scan tool for obdll will connect but you need the cable..

And thank you for the advice on how to fix the dash lights, I will look into this problem, Lord willing, This week.

Is there an OBDII port on these or any where to connect in?

That is a problem you have to try to repair dash first see if any plugs are not secure into dash also l believe there is a board underlay in the dash see if that is bad l believe key switch ignition controls the positive side of the light bulbs in the dash the check engine light l believe is controlled by the computer for ground. Check all fuses and wiring going to the bottom of dash if you do not address the dash problem you can not find this problem.

Yes sir, Non of the dash lights work, no illumination ever.

Ok are you trying to tell me that when you turn the key on the lights on the dash like like oil pressure and charging light and check engine light does not turn on and go out after the truck starts. Or are you telling me there is no check engine light that is on when the truck goes into limp mode

Ok I appreciate it, do you have any advice becasue non of the dash board lights up. This thing derates after about ten minutes of running. Shut it off and it will run smooth again sometimes instantly and some times after you let it cool down a little.

It is not a common problem for that part to go bad first if the check engine light is on you will have to scan it to see what code is in it and if not you will have to do the petal dance and count the blinks to see what code is causing truck to be in limp mode if you need to know what to do get back to me.you can not guess as to what is causing this.
