Linde (& Baker) B-30 TES:
Schematic/wiring diagram/manual help

Does anybody know of a place I can get some service information on this model? The people we got the truck from are gone, and others tell me the thing is so old we should just get another truck.

I've been tracing wires, but it would make it a lot easier if there was something for reference.

Thanks in advance for any help

The truck was manufactured by Linde for Baker. It was probably the most popular selling 3 wheeler on the market and pretty easy to work on.
There are are a total of 4 directional contactors. I would say that you still have a problem with the steering switches or associated wiring.
The pump motor circuit is direct battery voltage. You either have a direct short or the contactors are stuck on.
I would think that your local Linde dealer can troubleshoot and fix this truck very quickly.

The info from the nameplate -
Mod B-30-TES
Ser 324 409 5043-15
SO 43898-L
Made In West Germany

I believe it's a Baker, from before the Linde purchase, but it does seem to be metric bolts. It's blue (really, and it looks like factory paint), with white tires. I think they called it a creamery truck. I don't see any I.D. on the control, but it's an open plate design.

The first problem was that it wouldn't move at all. I found that the limit switches at the top of the steer wheel were miswired. I got it to actually move now, but there is still something else wrong. There are 2 sets of F/R contactors, if the set on the left are not pulled in, the truck won't move. No SCR hum, yet the right side contactors operate as the F/R control is operated. I'm not sure if the 4 power wires going to each drive motor are for a split winding control, or the contactor sets independently control the motors. I really didn't want to have to disconnect everything to track the wires back.

The second problem I'm still left with is that the pump motor runs constanly. I checked the switches at the lift levers and they are working. I traced the wires back to the same card that controls the power steering pump, but I'm not sure if there are other inputs for this circuit that may override the switches.

Thanks for any help,
Ken

how about you share with us what the problem (symptoms) are that you are tracing the wires for?
and a serial number.
is this a linde-baker product, (is it red paint and metric bolts) or is this from before the purchase by linde? (white paint truck, SAE bolts) and can you tell what controller this unit has?
