Hi guys

Finally got around to getting FS out of car and reassembled since UKPP,had to remove back box to get in car.

I believe all wires in correct position, seems to boot, but nothing works, only a beep and a few inserts light. So much wrong that I don't know where to start!

the 2nd fuse on the right of this had blown, so replaced and it all started working for about 1 minute, then bang!!! and lots of smoke.

F112, was a 4A, replaced with a 4A, manual says 7A.......
 
C11 - Manual says 1KP, 50v, +-20%
cheers rudi
 
Was the blown fuse a sign that it was failing, or is something wired up incorrectly?
 
I've seen this before, you've probably got a coil voltage short (50v) to a flashlamp/low power coil (20v), that's why the capacitor for the 20v supply has exploded, as you've exceeded it's voltage rating.

You need to find the short between 20v and 50v before doing anything else
 
I've looked for anything that may be causing a cross circuit, but no signs...... could I make a mistake with the connectors of different voltage to cause this?
 
good chance grizz could be right there.the manual tels you which colour cables should be in each connector to check if its the right one.the wpc manuals are helpfull wrt that.
 
Check with your meter to see if there is a short between the 20v and 50v test points, with everything wired as it currently is just for verification, but yeah, it sounds that it could be as per Grizz's post above, then after you swap the connectors, check that the short goes away, then after that, you can look at replacing the blown cap
 
Ian,
Check the black connector at bottom left hand corner of power driver board.
Looks like it's one pin out (bit blurry when zoomed in) but could be it.
