Somewhere in the system, there is obviously a current leak - I presume it is probably the hand controller, as touching other parts elicited no tingling (the current is SO low - thankfully LOW amperage - as to only tickle like one of those trick handshake thingies).
I am no electrician, so when I disassemble the hand controller, what should I be looking for - a frayed wire, a wire touching the metal casing, or? Only feel it at certain points like the face securing screws and hook.
I am sure it will be a simple fix, but I sure don't want to be out hot and sweaty or cold and dewed up touching that thing  
Other than that, WHAT A MOUNT! Sure does sound like a gas turbine spooling up when it ramps up to slew  Quieter than the EM400 too, without that odd "reversal" sound. |
Might be something wrong with the hand controller cable which just plugs into the hand controller. If you know someone with an EM mount you could try swapping hand sets. Weird though. I have an NJP Temma 2 (not the PC) and have never experienced this, though I don't use the Tak 12V/24V mains converter. To better understand and fault find the problem I would think you would need the wiring diagram. Work out which pin the power comes through and using a multimeter, test (continuity test) from the pin at the end of the hand controller cable to the case. I would also do this with the hand controller cable removed from the hand controller, test the connector on the hand controller to see if there is a short to the case.
