It is grounded direct line to the battery. I must admit that I'm not surprised, I've had 3 Denso unit failures on other bikes of mine, and Ducati 'regs', where this unit was sourced, has a notorious reputation for burning up batteries because of too much voltage.
Any thoughts? Improper wire connections surely would result in 0 voltage output, or a complete short, I think.

It's essential to have the black wire to the rec unit, which feeds from a switched positive, to have a good connection. If it had the supplied plug, clip it off and replace it with something else or, better, solder it directly to a switched positive. It took me weeks to figure out he supplied plugs were bad and I was fighting high readings like you are.
