Thanks all for the responses.
From the research I think the mount is a Losmandy Titan 50 () but happy to be corrected.
The controller is a Gemini 2 with LCD display (). The mount was having uncommanded goto issues so the Gemini Controller, cables and motors were sent last year to Bren Smith in Australia who replace the mount CPU and tested it and replaced the battery. I'm running it off a PSU @ 16v with 4 Amps.
I also had to replace the DEC gearbox casing as it had split and the motor would not screw in firm.

I was connecting to the mount via NINA and it set the time GPS? - which looked accurate to me - (I'm in Wellington New Zealand)and rate tracking as sideral. I aligned the mount using SharpCap on the guide scope so I have confidence that was good (no polaris here to point to).
Via NINA and PHD2 I set up the guiding via the setup wizard which failed with the following result:

I could not get it to guide at all using PHD2 and it would immediately start pinging errors at me.
I took the mount indoors and now get an error on the handset of "DEC : Heavy Duty Tr." - Though I did swap that motor with the RA one during my diagnosing.

The mount does move at slew speeds on both axes and can return to a Home with CWD reliably so I think the motors are working to some degree and when tracking with sidereal rate I can hear ticking from them.? The mount hasn't had much TLC for a while and I have noticed areas of corrosion around some of the bearings and it does seem to swing as freely as I would expect when not loaded up. It's also really difficult to slacked the DEC clutch wheel.
