If you take the starter motor off there is three tests you can do. To do this turn the starter motor on its side so that it looks like a figure 8 with the big cylinder at the bottom:

1. Motor test- this is done by earthing the motor with the return lead off a 12V battery and then putting the red lead on the bottom terminal of the top small coil.
The purpose of this test is to see that it spins freely.

2. Pulling test- this is done by leaving the earth in the same spot and putting the red lead on the left, sort of notch off the side of the small top coil. This test shows whether the pinion gear spins slowly whilst coming out to engage.

3. Complete test- this is done by leaving the earth in the same spot then putting the red lead on the top terminal then having another lead bridging across to the little left hand side notch thingy from the top terminal as well but do not fix the bridging lead just hold it with insulated pliers and make a firm contact.
The purpose of this is to see that the complete proccess works and the pinion gear comes out and spins freely. you may also load it up with a piece of wood.

In all these test make sure starter motor is secured in a vice. These tests ONLY applies to pre-engaging starter motors. I have never had the SM out of a soarer. Does anyone know what type they are?
