Hi Gang - Just a quick question to see if anyone knows how to power up this mobile to check for functionality without the use of its natural power cable? This unit has 3 prongs aligned with each other and my goal is to fire it up with an external power supply and alligator clips. If, assuming the pointed end of the power plug is facing upward, which prong would be the hot (Positive) and which one to ground / negative? Any advice would be helpful!
Thanks in advance and 73s John
