Yeah seems to be a problem on the board somewhere,I'm comparing continuity on the tilt side of things to the pan side,I'm a bit useless when it comes to following circuit diagrams and a bit wary of where I'm sticking my meter probes especially when powered.Reading a old thread here on blue room points the blame on the 1k5 sensing resistors but they appear to be ok.Maybe it's tracking somewhere after corroding as these fixtures were laid up for a long time
Yeah there is no power to the motors,if I swap the tilt connector onto the pan on the motherboard,there is power and moves correctly Obviously putting the pan connector on the tilt side does nothing.I've seen pan and tilt problems where they don't move put there is power on the motors and others that the movement is jerky and lacking torque
so due to the lockdown I have plenty of time on my hands so started to go thru the broken pile at the end of the lockup.Started to go through 6 mac500s and now left with two that are not doing anything on the tilt.Motors,wiring and drivers are all ok,checked the current sense resistors and the readings are the same as the ones on the working pan side.Anything else I can check
