This is a very old 3-wheel truck and the problem I had was the truck stopped working, before this happened, sometimes when you pressed the accelerator nothing happened, other times it clicked and then started working.

The wiring in the control box has always been a mess since I got it so I took off the box and tried to clean up the contacts between the fingers of the "speed control" mechanism. Some of the contacts were severely pitted so I built them up with solder and filed these off.

The problem I have is that when I removed the fingers of the speed control some of the connections slipped out, all the wiring has been butchered and unless I cut back into the loom it is a bit difficult to see the colour codes. So I have either mixed up the order of the connections, or caused a short somewhere. When I re-connected the power and tested it , the truck started then stopped with a blown 20A fuse in the control box.

I either need a replacement control box (only the "speed control" part, the contactors work fine ) or an exploded assembly/wiring diagram so I can re-wire the connections to the speed control elements. The control box is a Lansing Bagnall 6C3 -24V Serial number 66045535
Any ideas??
