My berlingo has quite a few problems, as a result of the previous owner not changing the brushes.
The van charges to 100% but when I go to drive, there's no click from the contactor and the electrical fault light comes on.
The commutator was quite scored from the wires in the old worn out brushes.
I've removed the motor from the van and took the casing and the armature to the local engineering works.
They pressed the armature out from the casing, resurfaced the commutator and replaced the bearings and the seals on the motor.
I've changed the oil the gearbox and am at the stage of reassembling the motor. I just need to get a new set of brushes. If any one has a spare set of brushes that they'd be willing to sell me, please send me a pm.
Once I have the motor back in I'm going to look at getting the controller working.

Hi I was wondering what this cost.
Looks like you have quite a project there! Good luck.
Had a look at the main circuit board of the controller this morning
I couldn't spot any broken traces or blown components. There was just one bit on the board where there was a small amount of white powdery residue. Hopefully the controller is okay, and the Electrical Fault Lamp was triggered by the worn out brushes.

Some nice work there old chap, looking at the PCB It look's like water damage to me and I believe that part of the circuit is responsible for the HI side drive of the main IGBT that PWM's the armature so it’s a hi voltage part of the pcb. Also the screw heads are corroded this may or may not be the actual fault as the IGBT could have failed due to the comm arcing Hope not
Could try putting it all back together and doing an ECU reset (pack fuse out then the 12V,wait a bit and 12V back on then pack fuse back in) and see if the fault go's away, but I would use pcb cleaner on those deposits (With the Power off)
Best of luck

Van seems to be driving normally as far as I can tell.
I wasn't sure where this lead attaches too. It comes from the negative terminal of the axillary battery. I think it goes under one of the bolts of the controller box. Could someone confirm this?
My wiper seem to rest in the wrong position. When they're on they go the full distance over the windscreen. It's just when I stop they come to rest as in the photo.

It's the earth for the controller, if i were you i would connect it ASAP. the bolt that holds the controller down on its back left the one under the 12V battery not the one under the heater, goes though the ring terminal and then in to the controller and body.
This could be why the fault light is on once you have refitted the earth do a reset and see if it comes right, it's nice weather for it
