Make sure your battery lug connections are good and that the negative it
making a good ground.
If so start at the positive battery terminal with your VOM and check for
12v, then move to the fuses and check
there and keep moving away from the battery checking until you find where
you are losing your voltage.
hope that helps. With no 12V anywhere and thefuses good it could be a bad
ground. I don't know anything
about the InteliPower and Charge
Wizard just electronics in general.
