 Frank,   
I'm looking at going with the timer system that I posted that was used for 
trim tab position indication. 
Just need to time the stroke of the actuator with & without load to 
asertain wether they are the same. 
I've come across circuit diagrams that could be modified to copy this 
system at a cost of $10- to $ 20-. 
However as I've said I'm upskilling in electronics & it might be a 
month or two before I can do it. 
If I get it right I'll send you the wiring diagram. 
Alan
