The red light on the battery gauge is flashing when battery is connected whether key is on or not. The gauge does not register anything even though the battery is fully charged (reading 37.4V). I can drive the forklift in forward and reverse but cannot move the forks up or down, tilt, etc. I am able to manually move the forks if I press in the contactor but the hydraulic motor sounds really noisy. It is an older forklift (1991) so if there are error codes I have no way of reading them. Only thing on dash is the battery gauge. I have scoured the forums and tried a few of the suggestions but without a service manual or error codes to work from I am kind of stuck.
The model number is ERC040JAN36SF084SR SN/N505220
Any help finding a service manual or suggestion what I can check to try and get this thing running again would be appreciated

Thanks Swoop. It was the older battery adjustment with 2 black knobs on it. I reset it and everything sprung back into action. But now a new problem. It is leaking fluid somewhere. Not sure if it is hydraulic fluid or brake fluid. Any chance you have a service manual or know where I can get one? I have looked everywhere and even called the local yale distributor but cannot seem to find one for this year/model.
sometimes after charging a battery if it sits for a few hours before you plug it into the truck the voltage may drift down below the reset point the battery guage (BDI) is set for and it will not reset when you plug it in.
You can try charging it for 15 mins and then plug the battery right in and see if it resets then.
If it does then you will have to adjust the reset voltage setting to compensate for this.
If this does not affect the problem and the guage will not reset even after adjusting then the guage may be defective.
Depending on which guage it has the adjustments may be on the back of the guage, if it is an older curtis guage it may have an addition controller it hooks to that has 2 black knobs on it that can adjust the VPC and reset voltages.
you can look on the guage and see which curtis guage it is and go to curtis instruments website and look it up, they have manuals on all their BDI systems there.
