Have a trouble with this truck, when i drive (forward or in reverse direction), and at the same time move lift or tilt, traction disable.
any idea?

jaajajajajaja...... the "big" trouble......... a litle bit in a cable touching the chassis.... thanks a lot for your comments, and if you can share the service manual with me....please... thanks in advance
thanks swoop223, about the battery, this is new and have more than 75% of his s.o.c., the trouble is only when I use the levers (control circuit) but if I make to work the pump directly of the contactor there are no problem and the traction works fine. the tune up is for checking the parameters in the ev100 card, because i check it and this are to different than the hyster with the same card, capacity, controls and system.
Hi raul,
well this is why we suggested to do a load drop test on the battery while operating the truck, because it sounds alot like its loosing the voltage needed to run the drive. The hydraulic system pulls a heavy load on its own and being that it is contactor controlled and not scr it pulls a consistent direct load off the battery when engaged, it is not tied into the main control other than the BDI for low battery lift cutout, it just taps its power off the main power circuit on the bus bars which are tied into the same circuit as the drive where it taps its power off the main positive standoff. If the voltage drop is too high it can cause the drive to drop out. At least from the symptoms you describe that is what lead us in that direction. Loosing drive when hydraulics are activated is a classic example of a battery low voltage issue, especially if it is contactor hydraulics. The code 57 might just be getting triggered because of low voltage across the drive circuit.
You may want to go back and double check the drive fuse and all the bus bar connections on the contactor panel. Make sure there are no wires rubbing against any bus bars or any wires routed around any contactors make sure they are not rubbed or melted and stuck to any grounded component.
Now as for the rapid tune up settings? i do not have the yale manual in front of me at the moment or on this computer but i do have them and i will get back as soon as i can and post them. I'm fairly sure they will not help this situation but for future reference i can give them to you.
somebody have the tune up for this EV100 card (IC3645LXCD1HT OR TH I DON'T REMEMBER WELL), If some one can share the service manual for this machine, I very appreciate.
swoop223: the error code is 57, (current limit), i try all, change the entire harneees, with the current sensor and the conector, the display is the std. (only a round curtis display) it's not a premium, and the system are not scr hydraulic controled.
the problem i have is a short circuit that´s disabled the traction when use the hydraulic levers, the only contact they have with the scr control is the bdi in pca#2 this go to a driver and then to the negative coil of the contactor pump.
are you getting any error codes on the display when this occurs?
what type of display panel does it have? is it premium? or normal display?
Premium displays have the 5 buttons across the bottom and if you press and hold one of the buttons it will flash through the stored codes in the system and tell you the error history for the drive first and then the hydraulic. Drive codes will be 2 digit codes and hydraulic codes are 3 digit codes. (this is for premium hydraulic only though) if it has contactor controlled hydraulics then this does not apply.
Thanks For the advice, swoop223.
The voltage is right and no problems with the battery. The complete model are ERC040RAN48SE083 and the serial is K550502.
If any have the service manual, schematics or the electro-hidraulic diagrams, I'm really appreciate if You share with me.
still dont know the series of the truck
what are the letters after the 040?
titus is right on any of the GE controllers code 57 is a current sensor low voltage error.
So this is 48v truck?
is this the voltage you read when you put meter across battery?
a fully charged 48v truck will read somewhere around 49 to 51v depending on the condition of the battery. If your just getting 48 then that battery is dead... hence causing this code i'd say ;o)
keep the meter on the battery and activate the hyd pump and stall it by bottoming out a tilt mode and then see what it drops to while holding it, the let it go after about 15 or 20 seconds. It shouldn't drop too far below 48v. If you get a large volt drop of lets say more than 5v difference then you should charge the battery, then re-check it, if still dropping alot check cells and see if there are any bad ones.
just a guess though since i have no accurate information to go on yet
Hi Raul.S
If your battery checks out Ok then I suspect a problem with the current sensor wiring check the green and yellow wires are connected correctly, yellow to PZ3 and green to PZ4 on the control card.
Check the power cables are connect correctly in the motor circuit.
Regards Titus
thanks a lot for the response, the voltage is 48, idon´t know if the voltage drop when put the pump to work..... let me check the model, and the error code are 57.......
many questions...
- what is full model number?
- got a serial number?
- like edward asked, what is battery voltage and what is voltage drop when operating pump?
- does truck have a error showing on display?
what is the voltage drop of the battery at rest compared to under max hydraulic stall load? at the battery cables? then at the cables just before the pump contactor?
