I picked up a really big motor for the MR2. Well, I just got it because it was £100 and 12" diameter and working.
It is an old 72v milk float motor, a Morrisons MD5

It runs like this.

There are a couple of cracks through two of the comm end mounting bolt holes but I don't think they will be a problem unless I need to advance the brushes.

I really like the art Deco look of the drive end.

I have started cleaning and painting, just red oxide for now until I can decide on a colour.

This is how it fits on the gearbox using a wooden mock up.

CV joint clearance is an issue but I am trying to solve that.

It is a tight fit in the engine bay too.

So I need to have a very short adaptor that will look like this.

What I will do is to use a larger shaft bearing and incorporate the coupler inside the bearing.

However, after all this preperation I have no idea if the motor is even going to be suitable.
It has six cables like this.

I have tested like this.
Test 1: Connect F to battery positive, E to A, and B to battery negative. Note direction of rotation.
Test 2: Connect F to battery positive, E to J, and H to battery negative. Note direction of rotation.
Results:
Test 1: Clockwise seen from comm end, 965rpm.
Test 2: Clockwise seen from comm end, 925rpm.
Any thoughts on how best to connect the motor or what else I need to test or measure?
