The pan and tilt motors have 4 pins but only use 3 wires (all others in the VL2500 use 4). My limited stepper-motor research tells me that it probably has three windings with a common return, rather than two separate windings? In any case, I have a brand-new motor to compare it to, so I'll just...
This is all great advice, thanks.It looks like my first step will be checking the wiring for shorts.Once that's done, does anyone know which pins I should be checking on the pan motor?
So... I just turned on a VL2500 Spot (2004-era). Just as it started to home, I heard the faint snap-crackle-pop of a failing circuit board, accompanied by the telltale smell of burnt plastic, and a decent amount of magic smoke wafting out the vents of one side of the yoke.Sure enough, it...
