I just spent a few hours sim racing and testing. The JRK's performed without a fault. Thankyou Bob, Dave, and Yoko, the help and discussion of possible solutions to these types of issues is always productive.
"On Reflection": It is very typical of how faults are resolved, particulatly in the DIY community.
I have fixed my issue by considering all the information I could get at this time, from you guys, my own experience and any other source that invades my brain from time to time
I feel it is important to say how dificult it is to track down intermitent faults. Sometimes they are there, they sometimes they are not. It always leads you to think you have found "the answer" but sometime you are heading up the wrong path. ( maybe that is a philosophy on life

) Although we may have
similar problems with the electronics or mechanical hardware, we must realise that each of our projects is unique. Motor type, motor position, cabling locations, power supply type, where the electronics is mounted, length of cables, type of cabling, where the PCs are, operating environment, electrical magnetic fields, our practical experince and understanding of the electronics systems and software and etc...etc......... all are
unique to our own instalations-----
It is a wonder we get this stuff going at all
