STBs = Ultimo4K, VUDUO2, VuSolo2, Alien2, AzBox HD Elite, ET8000:
Dishes = 180cm PF, 80cm offset, 60cm offset, Sky mini:
LNBs c120 for PF dish = Ku-Band White Smart Titanium (modified to c120)
and for C-Band Titanium C1W-PLL

I have a 1.80m PF driven by a 10 year old 24" jack actuator and a (21 year old) Pace MSP 200 positioner. It has been fine for many years but last night it stopped working.
I could hear the relay in the positioner click but the dish did not move.
I suspected the jack so stripped it down to check the connections etc. All looked well so re-assembled it but it was still appeared dead.
I then dug out my very old "Super Winch" 24" jack (why do they not make solid beasts like this anymore) and replaced the apparently defective one. It worked.
I then proceeded to set up East/West limits but on the second drive across the arc that too stopped working.
I checked the Pace MSP 200 service manual and that said for my symptoms (display OK, clicking relays but no movement) check fuse FS1 and/or short circuit on cable.
All fuses in the box are OK and a meter on the cable indicates no S.C.
However, I did check the output voltage and instead of 36V it was kicking out just over 50V (no load). Is this normal?
If not, I now wonder if the high voltage has damaged both jacks?
How can I further test which item is the cause of the problem? Obviously I do not want to buy another jack if it is the MSP 200 that is faulty for fear of damaging a new one and vice versa. I do not have another positioner (or 36v source) to test with.
Any ideas how I can proceed anyone?
TIA
