Need some help. I am located in Waterloo, Wi. That is between Madison and Milwaukee.
I have a Seeburg FC1 (1973 model) that we bought 25+ years ago. It worked fine until a few weeks ago. Now it does the scan and no selection thing. I found a blow fuse in the control (DCC1). It is on the board on the top and to the back. The fuse it the one on the top. I changed the fuse and it just blows again. I have read all the stuff about checking the read/write etc etc. I don't have the equipment to check and don't know where the various things they say to check are. I work with computer software (day job) and my hobby has been restoring cars. (Might switch to jukeboxes once I figure this all out).I can fix almost anything if I know what is wrong. Is there anyone in the area that would consider giving me a hand? I will fix it just need to know what I need to change. I will buy the beer.

Thank you,
Joe
 
I was just experiencing the same issue in my STD4 last night. The cause of mine was a bad diode inside the grey box. You might try unplugging the grey box, replacing the fuse in the DCC, and power it back up with the grey box unplugged. If the fuse does not blow, then you can at least narrow the issue down to the grey box.
 
Thank you for the reply. I did do that and found the fuse did not blow. How do you test if the diode is bad?

Thank you,

If you are not experienced at repairing electronics, you may be better off to replace the grey box. There are some repair shops on the web that exchange your broken box + some $$ for a refurbished one.
 
How do you test if the diode is bad?

You have to seperate one leg of it from the circuit board and test accross it with an Ohm meter, alternating polarity of the leads.

Better yet, use one that has a Diode test function, most newer meters have this option nowdays.

You'll get a reading in one direction and nothing in the other direction if the diode is good. Readings in both if shorted, and nothing in both if open.

Like Hatrick said, "if you are not experienced at repairing electronics..."
You can mess up a lot more than you'll ever imagine real quick in there.
