Hyster E30XL:
Drive problem

Hello, our old (1987) e3.00xl has virtually zero power fwd or rev, it will turn the wheels in both directions when raised, but very slowly. I suspect an scr issue, can these be repaired in any way? Or is the machine scrap.

Hi Mark,
Looks like you're right regarding CC Power. Shame they've dug us out of a hole several times but just looked at the last time we used them and it was 2019 so i guess it shows the market has moved on and everything is being kept in house by manufacturers these day.

Haven't seen any pictures...if you click on my "Reply by" Dez_A signature link, my e-mail address is listed inside.

Service life of a forklift is proportional to how well it is maintained.
That's a great help Dez, I think CC Power are no longer trading. I have some photos that I can send over, thanks again for your help

Hi Mark,
CC Power based in Stockport Cheshire are a electronic repair & diagnostic company, not the manufacturer of the PCB. If you talk to Jed or one of the team and tell them the details from the sticker (usually Model No. Serial No. and Job No) they can advise what control system is fitted to the truck and what the PCB you have is.
I suspect you have a Cableform system but if i'm being honest it's so long since i've seen one, memory is a bit foggy.
If you want to e-mail me a picture (in signature) i'll try and identify for you.
Dez

Yes , disconnect components until frame ground goes away. Usually the frame ground is caused by brush dust in motor since it was rained on that could cause dust get wet and collect causing frame ground. Disconnect
Battery and blow out motors with air and check
Before you pull components if not then check
Contractors first with the hyds and steer slow as well you may have shorted control card assy

Im assuming its a short in the scr of some sort or a component on the pcb damaged by the water, our forklift engineer has said to disconnect each item until there's no voltage showing to the frame?

Hi John, its a CC Power electronics Ltd SCR unit Model no 8022 36-80volts, serial no 01 04 8948. The forklift is a Hyster E 3.00XL C108A02237G
Circa year 1987. The fwd and rev contractors pull in as they should as does the hydraulics contactor. The 4 x pcb leds light up as they should when requested. And the wheels turn increasing in speed as the accelerator is depressed but nowhere near fast enough. It's as if there's not enough power being delivered to the motor. The motor brushes look fine.

Hi John , there's a small printed circuit board say 4" x 6" attached to a larger black potted block with some large terminal connections. At the top of this there are two components. One is a small copper wound coil the other is a square block with some small control wires. Then there's also an scr bridge rectifier (ive identified this by looking online). Sorry to be so vague, it's difficult to explain without sending photos

Can you describe the control card ?
Is it about 12 x10 in and wires on both sides adjustment pots in center ? Or larger with solid metal cover ?
