Clark ECA25:
No Hyd's or power steering

Afternoon folks!

One of the lad's has a bit of a head ache with the above truck, S/No E138104GEF4510 if that's any relevance.

Anyway, it'll attempt to dive but it's pushing against the handbrake, has no hydraulics or power steering.

He say's the direction lever has three positions on it, foward/reverse and park.

He can't get the hydraulic actuated parking brake to come off hence the reason the truck will drive, but against the brake.

We assume the power steering or the hydraulic system must operate first for the brake to release??

Does this type of truck cut the power steering and hydraulics when the brake is applied?

Strange I know as it's usually the drive that would be cut off when you apply your hand brake.

We seem to think the truck just isn't seeing something, safety switch for example?

EV1 control system by the way.

Sorry it's a bit vague, I haven't seen the truck only talked about it over the phone.

Cheers lads!

No the hand brake don't stop the HYD the hand brake cuts out drive but since that's not working some one bypassed the brake switch or the switch is failed in the closed stat. I would check fuses the small ones see if there was a short in the signal circuit nd caused the fuse to blow. Is the HYD contactor trying to come in but welded or stuck open. check and see if its getting power and the fuses are good than its got to be a broken wire. But sounds like blown fuse. Truck will drive fine once hand bake released besides no power steering. P.s. Also if this truck has an battery cut out system on it than that my have failed and will be ezer to Bypass u will need to get the Curtis battery analyzer model number to look up how to bypass online
