I am in the process of trying to do the 4 field coil, 4 brush Prestolite starter motor upgrade on my MK III. I am using the original housing rather than a Harley/Prestolite housing and have installed 4 field coils and 4 brushes as well as a needle roller bearing to replace the drive end armature bush. The problem that I have is that I cannot get the motor to run in the correct direction. It runs very well but only in the opposite direction. I need very specific directions on where the brush wires should be connected to the field coils and what holders all 4 of the brushes should be placed in. I have the field coils connected to the original connecting spot on the housing, so if this needs to be moved, please let me know this also. Thanks.
