papajam, or anyone else familiar with 750 Spider park mode for their windshield wiper motor - I need help. I have checked the shop manual and it has information for three different wiper motors, but none - that I can see - are this Lucas.
I'll add that I'm bench testing so please, no going over which color of wire goes where.
As you can see, it does not have the circular brass parking plate. I'll add here (I have both a '62 transition 102 and '58 750 Spider in the shop). Without too much work I got the 102 unit working 'well' and parking. When I connect the -- to #1and + to #2 nothing happens. But once I connect a additional wire on #1 and ground it, the motor runs and when removing the ground wire, it stops and parks just fine. I'm a bit concerned that the rotation isn't enough, so I need to dig into that.
I want to add that the internal brass plate is insulated from the cap so that the wire coming from #1 isn't always on - which to me is the only way it can work.
However arm B on the 750's has a direct connection to the 750's park arm - which logically makes it run once #1 and #2 are connected. Removing the #1 wire, then grounding it does nothing. It only stops the motor from running without parking. I can only assume that the wiring is different for this model of Lucas motor and gearbox - but I can't think of any other way to wire this set-up. I could insulate the park arm, but have to believe it actually worked...apparently by magic. Since the wire from #1 is internal within the motor and goes directly to the park mode unit/parking arm it is definitely always hot.
I replaced part 2 and part 5, cleaned everything up replaced two part, but it is obvious the way the two rivets goes through the entire stack it has no choice of not grounding. Since the holes are larger on part 3, which the wire attaches to, I wondered if making sure it wasn't touching the two rivets 'might' do 'something'. It couldn't of course since the end of the arm is always in contact with part 1.
If anyone has gone through these earlier wiper motor set-ups with success, please tell me where Im going wrong.
On another note there is a sound when the motor runs which sounds like saying 'clock'. The arm that attaches to the wiper 'drivers' moves around. Nothing inside the gear box appears to be 'out of place'. There is an adjusting screw on the outside which goes to the end of the motor's worm gear end. The 102's adjuster was touching the end of the worm gear so I did the same with the 750's, but there was no difference.
Again, any thoughts/ideas in this area would also be appreciated.
