i`ll send you a manual, just need email. dont put @ symbal, or.
they will remove the email
Are there any fault codes? Is there an economy switch?
Votage seems good there even using the diagnostics on the forklift. Temps on the inverter seem good and on the motors. After a charge the vehicle was up to 5 mph but justs to 4mph and now the battery drains. 6am full charge to 9am it at a little over half. I had a worker tell me the forklift is capable of the avg of 8 to 9 mph.does that have to do with the inveters npt putting out engouh. Just not sure where to start with no manuals... thank you for the help so far
Doesn't matter where you check the battery voltage so long as you are reading battery voltage.
Battery voltage is battery voltage. What you are looking for is to see how much the standing battery voltage drops when a high current draw load is placed on the battery.
Voltage will be the same everywhere in the system.
so id be checking for a voltage drop? ill try to check that when i get there on monday. so basically check this at the motors? to see if theres a difference in the power between the starting out at 5 mph, then the drop at 4 to 3 mph?
if it was me, (and I have looked at a couple of electric forklifts) I would start with knowing the battery is good.
Do this by doing a "load test", where you read (I prefer a digital Volt meter) the voltage of the battery 'at rest' and then tilt back or (best) to run the forks to their max height, then read the battery voltage while the hydraulics are at "stall" [it takes more current to lift than to drive and it is sort of dangerous to try and read a meter while the machine is travelling]. if you have more than a 10% voltage drop between 'at rest' and 'hydraulic stall', you will need to get the battery up to stuff first. Do NOT stall the motor more than 5 seconds, it should only take 3 seconds to get a good reading.
