What's this wire?

[Wolfie]

This is the second time during the years that I've owned Tw150's that I've had to replace a starter motor.

Both times the new motors had an extra white wire that wasn't on the old motor.

Works fine without connecting it to anything but just wondered what it's for?

Those starters come in a few different ratings despite the same fitting , some are 1.2 kw and others 1.4kw plus. I think with the chippers and all the associated weight the starter is trying to turn its best to fit the higher kw starters, I have seen those spare wires used to operate dump valves on hydraulic equipment that would otherwise load up the engine while cranking.
