I have only ever dismantled a round wiper motor, so I can't say for sure. If it's similar to the round body type, one will be +12V, the other two would go to the switch: one to provide power when wiping, the other for the self park. You might want to ask Convertible Mini or someone else familiar with the square wiper motors.

Assuming it's a round motor single speed, (as most Mini square motors only had 2)
Green is +12V from the bottom fuse,
Blue/Green goes to p1 on the switch,
Green/Yellow goes to p8 on the switch.

These (both 1 and 2 speed) motors are a Lucas Australia motor, they have dynamic braking for the park position (unlike UK motors).

The main prob with these motors is water gets in from the wiper rack, and lays in the bottom of casing and rusts the slip rings on the bottom of the motor.
New slip rings are available from Mini King, or `Convertible Mini' on here.
There is a thread in the how-to forum on rebuilding these motors (both 1 and 2 speed).

Here is the motor. Square body, parks on the drivers side. Single speed. Reconditioned unit from mini king. Same as the old one.




Three terminals on the bottom.

Thanks John.

The motor seems to be working as it should. I believe the problem lies else where.

If you have a spare healthy battery or enough length of wires to use the disconnected car battery, could you disconnect the loom from the motor and run a direct line from battery to the motor and see if the speed is different? If it is the same then the fault lies at the motor end and if it's faster then you know you have a problem on the loom side.

Does anybody know what the three terminals are?

On square motor with park feature,
p2 goes to bottom fuse (Green) (12V+)
p3 goes to earth (Black)
p1 goes to p6 on the wiper switch (unknown coloyur in my book)

Takes from Deluxe and MiniMatic diagram (Oz production) in SP manual #64.
page 197.

did you get to the bottom of your wiper issue

I haven't looked at them since Sunday. I've had an extremely busy week. Probably won't get to them until Sunday week.

Thanks.. Just wondering what the issue was to store away in the memory bank

I have fixed the issues with wipers. It came down to a few different things working against me.

1 - the whole assembly was gunked up with old grease
2 - the cable had a kink in it that needed straightening
3 - the springs in the wiper arms were too strong


Thanks for every bodies help.
