The AP900 has a tag on the inside of the mount base side, left inside facing the CP3, to the right of the DEC adjuster if you look from the front of the mount. Blueman

Thanks. Wow! My mistake for not asking this question years ago before the mount had 100 lbs of telescopes and cameras and some meters of associated wiring carefully routed! I think I'll skip the

Take the dec axis off. My sn is engraved on top of the ra axis.......

Not the CP3 serial number, which is easily visible, but the mount serial number? I need it for registration to get a firmware update. Thanks much!

UPDATE: After a couple of phone based troubleshooting sessions with George, the RA gearbox and the GTOCP3 control box were shipped back to AP. They replaced a spur gear and a cluster gear, updated

What are you running on the split power connector? AP has always recommended you power the mount on its own supply source. Sharing the power especially with dew heaters can effect slewing. Something

Yes, when the natural rubber decays, it could be difficult to extract. Maybe a stick pin with the end bent into a hook would work. I suspect your estimate of a year life for the elastic could be

Don, I too thought about inserting “something springy” intothe power socket split. However, elastic bands have a life of about a yearbefore they decay, and make a mess. Neoprene rubber might

Good luck on solving your power issue. One idea that just occurred to me to prevent the split center pin loosing contact on the CP-3 controllers, is to cut a small piece of elastic band and carefully

Gentlemen, Thanks to all that have provided advice and suggestions on my power issue. Based on your input I will: 1. Change to "autostart=yes" 2. Carefully spread the pin on my CP3 controller

This happens to me also. The problem is the split pin connector inside the box. I have to periodically spread the pins apart to fix this and have lost power at inconvenient times because of it also.

The mount will not get lost if you have a simple power interruption. In fact the easiest way to recover from a power interruption is to set your keypads to Autostart YES. That way you will ride thru

OK, thanks Marj. joel

Some AC-DC wall converters do not have enough filtering on the 12 volt DC side. As a result, the power can become erratic during slewing, which then can reset the servo controller and the keypad. What

Congratulations Dave and Howard! An awesome image and so timely!

Ron, Idon't think cables get any more "robust" than A-P cables. You are screwingit down after inserting it -- correct? Butyes, it's a standard threaded DC connector. I believe it's 5.5mm

Look closely at 12V connector on CP3 and you will notice the pin is split into two halves. Very carefully insert a small blade screwdriver in between the two halves of the pin and slowly twist the pin
