Tools you need for Forklift electrical Diagnosis 

Here is a brief history of the Hyster forklift with serial No: P005B03724J, Model:H5.0FT. This forklift had a problem sometime last 2 years. it was not starting and was down for over 5 months. When the repairs was being carried out, the following was replaced: 4 injector electric nozzles Rotary pump Cam-shaft sensor Crank-shaft sensor After repairs the equipment went back to operation. About a week work the forklift stopped working , no starting. Since then nothing has been done to the truck. Mr. Paul Stewart inspected the machine and discovered water in the diesel tank. He made remarks about the water in diesel damaging the electronic nozzles. With the introduction of the Gemster department as a technical outfit. we have carried out inspection and repairs on the machine, cleared error codes, another ECM was used in testing the engine, checked electrical fuses and relays in attempt to rectify the problem. Crank-shaft and Cam-shaft sensor was replaced too. Measuring the voltage on the nozzles after clearing all error code, 07.00volts was present. With the assessment of Mr. Paul and all the repairs done by the Gemster Team, it doesn't explain why only 07.00volts is present to the electronic nozzles. Tapping into your rich Experience on technical issues as this, We kindly request for your advise and technical solution on this problem.

Cool shop!

Ban-Joe! What a surprise to see your face... This is Stan from Atlanta

I am looking forward to seeing some hydraulic issues addressed. Currently I have a lift that does not want to engage the mast to the second level when it has a load. It does not have any codes, the mast channel is clear, there is plenty of fluid, the hydraulic filter appears to be free of obstructons, and it has been recalibrated. I think it maybe a valve issues. The lift is old and the company has decided to take it out of service soon. Nevertheless, I am interested in learning more about troubleshooting this type of mysterious issue. Thanks

Thanks for the info. Speaking of electrical issues, is it true that sometimes when a lift drives over a hole the controls are shut down and there is a reset switch? I was asking because I have a lift that powers on but no otther funtions operate after driving over a rough spot on the floor (a manager said at his old warehouse the techs would press a reset button).The only event code is 357, for an emergency stop switch short. However the spade connectors are secure and the SPST (in the E-Stop) is visibly moving when activated and shuts off power when depressed. Purhaps the issue is an Access 3 malfunction. What are your thoughts, given that this occurred after drive over a rough surface? Thanks.

nice vid did u ever worked on jungheinrich electrical forklifts is there a way to login to its online computers (analyzers) specially etv116 and efg counterbalance ?
