CG5 mount runaway slews - specifically ASGT

[mithrandir]

Are there any other likely causes apart from power? The usual causes are low battery, pin on power socket loose, or the long power lead having too much voltage/current drop.

I'm getting runaways in the Dec motor but not the RA motor.

I can't remember hearing about any other causes off the top of my head.

Does it always runaway the same direction? i.e always north or always south? If so it may be a sticky button or short across PCB tracks in the handpiece...:shrug:
