I had a problem with my voltage regulator a while back. it degraded to little over 4 volts, dimming the system way down.
While your cleaning your grounds, disconnect the voltage regulator and start the sled. If the lights are brighter then you have found your problem!
NOTE: don't rev it too much (over 2300 rpm). You could over voltage the system and it could blow all of your lights.
