Getting the satellite station set back up after several years of inactivity. My G-5400B rotor doesn't seem to be working and it appears it may be the control box so looking for some troubleshooting tips. It was working fine when I last used it so just want to confirm there really is an issue. Yaseu tech told me to measure across terminals 4 & 5 at the rear of the control box and said it should read 12-24 VAC. I'm not seeing any voltage on either AZ or EL so just want to verify that is what I should be seeing? Any other tips on troubleshooting the control box before I send it off to Yaseu?
