Is there anyone out there with an LX85 that knows how to use a multimeter to measure pins in a port and is willing to do so? ( A simple unpowered continuity test will be OK for the +12 and grounds )

A user recently plugged in a StarGPS lump and it got fried.

Also, part of the users PCB blew, but on measuring the voltages in the Aux port ( which supplies power to the lump ), he is registering that the ground and +12V pins are swapped relative to all other mounts.

I have attached a piccy of a std Meade control panel and what pins are +12V and what are ground for the Aux port.

If someone can check their port on the LX85 and confirm it is either opposite or the same as what i have attached, it would be most appreciated.

Nope. Several users confirmed it and Meade also confirmed it.

LX85s AUX ports are wired mirror image.

Early LX65s are also wrong but later ones got a revised board.

They put a white dot in the battery compartment to signify the later (correct) ones

but i always suggest users test for themselves
