Wanted - new column stalk set

[john]

So following on from that Peter the motor should park if you apply 12 volts to the motor terminal. You could do with borrowing a set to test your theory before shelling out. I guess you may be lucky. I did buy a set off ebay for £15. Cant remember what they were listed as but it wasn't X19, so look a bit wider than that. I looked at the plug colours and plumped for this set on the basis that they were the same as the X19 plug colours and when they arrived the wiring colours matched the X19 layout. Worth a punt on that basis if you see a set not listed as X19.

The 156 motor has internal electronics to deal with both the intermittent timer and the park facility.
In the park position you should as John says find a 12v fused supply to pin 1 on the motor.
In the intermittent position you should find a 12 supply to both pin 1 and pin 3 on the motor.
Pins 5 and 6 are the only direct connections to the motor, pins 1 to 4 are connected through the internal electronics.
The attached diagram is from the Alfa data sheets and shows the 156 motor and how the 156 switchgear is connected to the motor.

Disregarding the column stalks you should be able to tease the motor into working by simply applying a 12v supply to the relevant terminals one by one to prove whether it is operating correctly or not.
