Prior to ordering my new Meade LX65 8" ACF from a well-known vendor the other week, I called and ensured that they had scopes in stock and inquired about whether they were the newest production models with the Aux ports of proper polarity. The rep told me he wasn't sure, but that their inventory "had just arrived" from Meade and should be the newest version, whatever it is. When the LX65 landed on my door step yesterday, a check of the battery tray revealed no white marking. Either Meade has abandoned the practice, or I have an early reversed polarity model. I believe I read LX85 models have this issue as well.
I own a voltmeter and even occasionally use it in my automotive hobby, but haven't worked with Aux jacks like this before. Can anyone tell me exactly where I need to apply positive and negative voltmeter leads and what setting the meter needs to be on? Further, what results will tell me whether polarity is correct or reversed? I've seen some of the diagrams indicating what various wires in these connectors do, but am still confused without someone laying out the procedure for me. I tend to regard electricity as voodoo magic!
I've searched high and low on these forums, but can't quite seem to find a guide through this test. I don't have any accessories that would plug in there for the time being, but would like the ports to be functional for future expansion -- after all, I paid for them.
If I do have the reversed ports, I don't have it in my capacity to correct them. Who might I buy an adapting dongle from? Or should I just attempt an exchange with my vendor? I have seen StarGPS's special power cable at $30, but it seems custom designed for their device.
Thanks for any guidance!
