I have not made any changes lately. It is significant that the stepper motors in both Dec and Ra fail at the same time so it must be something common to these. You would think that if it were a faulty or dried out capacitor that the problem would be there all the time but it is not a marginal problem - the mount works perfectly or not at all. It almost seems like it would be an intermittent power connection. It is a pity that with most equipment these days that a circuit diagram is not included in the handbook. I will look on the net and see if I can find one. I used to be a radio tech so I am fairly familiar with fault finding but the mount electronics are a bit hard to get at. Perhaps if I take the board right out I may be able to see what is happening behind it.
