Thanks for the quick response. I read some of the information strings and did make the change to a regulated power supply from Radio Shack. I also took my time and made sure about the polarity. I suspect that what is referred to as the "Main Board" is where the slow blow fuse is located; not sure where the power board is or theDEC board. I have searched for an exploded view of the mount so as to not cause more damage unnecessarily; can someone help with that? Also if a repair location is known that would be great too. This telescpe belongs to a school and it is the setup they use for field trips and community outreach. The priest/moderator is along in years and I help him as much as I can; sometimes its more than I bargained for. I appreciate the help; my experience with this is the manual and articles I can read and locations like this one. Beyond that, y learning curve is a vertical line. Thanks again and God bless.
My son and I powered up the telescope mount and the telescope started moving in DEC. We quickly turned it off; would not power up after that. We changed the fuse; tried again and same thing. The fuse blows almost immediately now. We are using a Radio Shack regulated power supply. Any ideas on what it is we have done this time? Thanks and God bless.
