Default Vacuum wipers do work when engine are idling

Hi Darren

The vacuum wipers will, or can be made to, work well enough to pass a stationary test.

The reason I say this is I have large stuffed bear that rides with me in parades he waves his arm and hand to the crowds. His arm is animated with a CMP vacuum wiper motor in his left shoulder his arm waves energeticly at idle and driving low speeds.

You have not mentioned, if your C60L is a Pattern 13, but I see from your avitar is, so the inherent nature of reverse slope works much better in rain or snow than vertical or forward slope winshields. That the wipers did not work all the time when first use is clear by the fact that they had inside levers to manually operate them.

I have a problem with adding a vacuum tank for the wipers as its inlet line size and isolation valve would need to be careful thought thru so as to not take vacuum away from the brake booster.

Keep us posted on how your project develops, aways great to here about another CMP back on the road.

Cheers Phil
