Cirqus Voltaire F106 blowing

[jonathan]

Well it lasted 1 week before it broke!

Startup says to check fuses f101 and f106. Replaced F106 and it just blew straight away again. A quick google suggests BR1 needs changing, the equivalent being diodes 11-14 on WPC games.

I changed a BR on my TAFG easily enough. Any idea how much harder it is to desolder and solder new diodes in?

Got the multimeter out and managed to narrow it down to diode 13. Happy days

You will be ****ing that ringmaster before you know it lol

do you have to snip a diode's leg before testing it?
i am busy staring at my CPU board, and noticed it has dozens of diodes on it i'd love to check while i have it and the multimeter here with me. but no point if i can't test them in situ, i'm not cutting and fixing all those ****ing legs

You won't get a true reading if you don't snip one of the legs.

Well D11,D12 and D14 all read 500 on the diode setting on my multimeter. D13 reads 0. Good enough for me

I thought if they test good then thats fine, but if they test bad....then you should snip and try again. But I might be wrong.

All I know is that more times than not with pinball its a frickin bad connection or a short that causes all the grief. Components dont seem to 'go' that often really.

Bypass all of those diodes with small pieces of wire (or zero ohm resistors) Its a common mod to wpc-95 boards as it stops them from heating up and causing issues. I did it to my Totan and CV after both suffered from a similar issue with great results. Also, the magnets in CV can cause issues with the fuses from time to time. Check they are all the correct values fitted for the slow blow (oo err) variety.

Careful. That's only for the GI diodes. Not the power supply ones.
