The heatsink has a ground connection? I'm not sure what you mean. Are you saying that the
aluminum heatsink, when screwed down to an
aluminum plate, is
conductive? (I would hope it is; it's aluminum).
The check you MUST pass is: With the battery disconnected, measure resistance betwene the + PDB connection and metal chassis, and between - PDB connection and chassis. Resistance MUST be greater than 10k Ohms (try for much more). IF you pass that test, you're good to go.
