Well We're blowing breakers after the motor (original motor with a properly rated and wired plug) runs for around 10 seconds and it doesn't quite sound right (yes there is oil in the head). The motor had previously been run with no problems. I had to disconnect the forward reverse selector switch to put it inside a sealed box.

My wiring was:.....11-U1(blue)....9-U2(red)...........10-R(white)....12-S(black)
.............................................5-Z2(orange)
.............................................1-V1(brown)
With yellow and green to ground.
(outside contacts are on the bottom with the selector facing forwards and contact screws facing up).

Have I made a mistake in my wiring diagram or is this something else? Thanks in advance for the help.

Edit: Well after futher research (pictures on IH site) I've found that the left side is fine. That cuts it down to either white (10-R) or black (12-S) on the right side should be on top. I'd rather not just guess. If anyone can pull the cover off and look or already knows that'd be great.
