WG K7200 cap explosion! Help!
« on: March 21, 2006, 05:32:34 pm »
I'm working on a Wells Gardner k7200 at the moment. C101 keeps on blowing it's top. The high voltage comes up but sounds a bit strained. All large diodes and resistors test good. I can't keep it going long enough to test the B+. Any ideas?

Thanks

the only time i have seen a cap blow its lid is when its in the wrong way round or the voltage is extremely high

That was my first thought as well. I'm very careful when putting them in so it would be a rare mistake. The polarity was correct when I pulled it out. I replaced it and it blew up again.

voltage rating of the cap you put in?

160v.... I know the first thought would be that I made a mistake. It was my first thought as well. But, the cap was the correct voltage(160v), microfarads (@100 microfarads), and was put in properly (polarity).

inspect your chassis and make sure no solder/solder pieces is over lapping/touching in the circuit. Check T103 also for proper voltage.

I don't have a schematic for it. What is T103 supposed to be? It's going to be difficult to get a reading, because this thing blows the top out of the cap in a short time.

Thanks for the input, it's greatly appreciated.
