I think they are working, but I've noticed that when I turn the unit on to start tracking, the green light goes solid for a bit, then after a while the green light starts to blink.  Any idea what that means?

Have a feeling it means nothing, or all is OK.

Installed one on mine a couple of years ago and vaguely recall a flashing light. Eventually found it was nothing.

 

Will try check.

 

OK. Reads I am wrong:

 

The motor drive requires 4 'D' cell batteries (not included) to operate. A set of batteries will allow several nights of observing. The LED light is green under normal operation. The LED begins to flash in the case of imminent battery failure

 

According to Skywatcher the batteries are in imminent failure - seems a bit strong.

Assume the same as these. Somewhere on page 2, right hand side. Although it says 11. at the top.

I have the dual axis drive for my CG-4. The green light will blink as the batteries drain and then go red when the juice is insufficient to drive the motors. That is how it has worked for me, and the transition is pretty darn quick...

The blinking light indicates low voltage.  You need a bigger battery, or one that is more freshly charged, or a better power supply if it is plugged into AC.

Thanks... Using D-cells now may upgrade to PS at some point.

D Cells will drain and if cold, maybe unlikely in Tampa, they drop voltage and power.

Always be careful as they are 6v and more then one has been wrecked by incorrectly applying 12v.

 

My control box, has a 6V connector, assume a normal 2.1mm

 

I need and intend to make a small 6v regulator on some prototype board and use my sort of standard 12v lithium batteries as they seem better and even if they drop to 10 or 9v they will still supply 6v via the regulator.

 

Do have another idea, even madder.
