[amsat-bb] Murphy on my G-5400B control box

[Sebastian]

Seems I can't get a break from Murphy.

A couple of weeks ago, I received my azimuth rotor & G5400B control  
box back from Yaesu after the rotor had failed.

Yesterday I noticed the control box had turned off, and was generating  
a lot of heat.  Sure enough, I checked the fuse, and it was blow.   
Opening up the case and looking for obvious problems, such as cold  
solder joints, burned components, etc., didn't show anything  
interesting; other than a hot transformer.

Unit blows fuses as soon as they are replaced.

So before I call up Yaesu and am off the air for another 2 or 3 weeks,  
any ideas from someone who perhaps has had the same problem?  I had it  
connected to my LVB tracker, which no longer functions, as I believe  
it gets its power from the control box.
