Re: Lightning Hit on G5400B Help needed



In 2000 I had a similar "hit" on my G5400 rotors.  I wound up replacing:

1.   The position pot in the AZ rotor.  It arced over...later I found the
open in the pot winding and patched it with solder...works ok

2.   The 7806 voltage regulator

3.   The 10k az and el trimmer pots on the back panel.  I replaced all
four...they looked fine, but were "flaky" and the FODtrack driver couldn't
cope with the glitchy behavior.

Hope this helps...good luck!
