set up shows 90*parking the scope after trying to locate ,back at 90*, showed 79* or sometimes 96*.

Anyone have any ideas, Only thing I've done recently was silicon the the encoder cables into the mounting pole , I was thinking maybe a cable switch , but would that wouldn't change the angle readings intermitantly would it ?

Hi Graham,

Thanks for the post.

Firstly thanks to John B for the follow-up which is exactly as I would recommend.
Look for any possible slippage in the encoder coupling.

With regards cables, exercise the mount in Alt whilst watching the display in
MODE ENCODER and see if there is any apparent hesitation as the numbers
tick over. Also watch carefully for any ALT ENCODER ERR message which
is an indication that there has been a state change violation in one of the
encoder outputs, possibly from an intermittent open circuit on one of the wires
on your Alt encoder cable.

Best Regards
