George,
There are 2 terminals and an earthing screw on the wiper motor. This has to
do with the self parking feature. Check your wire colours and make sure
everything's going to the correct terminals and that the self parking
contact inside the head of the motor is turned the correct spot to have the
wipers park at the bottom of the stroke that leaves the blades in front of
the driver's side.

Subject: [Healeys] wiper motor short?
I've recently reinstalled a Lucas wiper motor that was out of the car for a
long time and bench tested OK when connecting the terminals directly to a
battery. Now that the wiper motor is back in the car there is apparently
something wrong inside the motor because now there is a direct short within
the overall electrical system. A check with an ohmeter shows continuity
between all terminals(and the case) on the wiper motor. If the wires are
disconnected from the wiper motor the rest of the electrical system goes
back to normal. If + and - is connected directly to the motor from a
separate battery the motor works fine. This seems to me like an internal
short in the wiper motor but if so, how can the motor work normally when
outside power is fed to it. Anyone have any ideas?
