Thank you for reading and we look forward to hearing your suggestions.

Teed,
What you describe is one of the problems I anticipated when using these blocks. The entry for wiring is meant to handle anything up to a #4 wire for the stock block or a #2 for substitute block. When using #10 with these blocks, it is very easy, I repeat, very easy for the strands of the wire to work up the sides of the entry and not be connected. This leaves you with the equivalent of a much smaller wire feeding the circuit. (Maybe as small as a #22) This high series resistance develops a considerable voltage drop at high currents. If the suspect Victors are feeding the Chalupas or drills or even the FPs then it is conceivable that poor connections are dropping all the available voltage and none is left to feed the motors. See my post earlier in the year about doubling or tripling the wire termination when using the supplied maxiblocks and power distro. It appears you have done the right troubleshooting so far. Believe what it is telling you and concentrate on the wiring.
Are you going to Midwest? I will be there with Wildstang and also inspecting. If you are there come and find me and I will help. Have the pit announce page me if you need help.
