if the cds is covered and the switch is right then maybe the SCR is bad on the flash board....if you do a search, Dkirk has troubleshooting guides on here for most of these viv 2 k flashes... look for those and go thru the trouble shooting and see what happens....
it may be something simple like a cold solder joint (hopefully) on one of your wires.....how bout good batts ?....I learned from 212 to look for the simple things you would overlook real easy first then look for the hard stuff..... I also read that when 212 did testing on these bf protos the the flash sensor that see's the cams flash also needs to be covered..
Roger, what video is that..?..... it looks like the one guy is trying to smoke a banana and the other guy is torchin it for him....LoL...
heres one link to your board,
http://www.hagshouse.com/forums/index.php?...c=21031&hl=heres a link with the exact same issue and board,
http://www.hagshouse.com/forums/index.php?...rouble+shootinghere are Dons tests for this board,
always make sure a modified flash board works properly before connection to the control board. I suggest you disconnect the 31657 board from the slavemaster, then run the following tests.
1) Connect battery to 31657 board for 20 seconds then measure voltage across the flash capacitor or flash tube. You should measure 280 volts.
2) With flash capacitor charged per step 1, touch the two ends of the trigger wires together and the flash tube should flash.
If the above tests do not work, then no point connecting the 31657 board to the control board until you get the 31657 board working properly. If the 31657 worked fine per the above two steps, then you know the 31657 board is working properly and can be connected to the control board.
Note : when talking about pins 1 and 2 on the SCR, the pins are 1, 2, 3 from left to right when looking at the side of the SCR that has writting on it with the legs of the SCR pointing down.
