sorry i reposted this but i noticed some things that had to be changed and the time i got to my computer after typing all of that on my phone i could no longer edit it!
your jumper is set right
What you want to do is first set your multimeter to AC and check you have around 12 to 14v AC on the AC terminals on the bridge.
If you don't check the fuse if you do then switch to DC on your meter and check for your DC voltage on the out put of the bridge and on the cap if you do have the Dc voltage then check at the display connector.
If you don't have the correct voltage at the display then connect the + lead to to the blue wire on the display plug and the - to the - on the bridge. If you do hAve the correct voltage displaying on the meter now then this will indicate you have a problem with the ground wire.
If you don't have the correct voltage then connect the red meter wire to the + on the bridge and the black meter wire to the black wire at the dmd display.
If you have the correct voltage on your meter now then the problem is with the power on the blue wire to the display.
Hope that makes scene ?
