shunted digital ammeter

[Dunderberg]

I bought a couple of digital LED voltmeter / ammeters for my Bronco II and the old F-250.

Wiring them seems more of a challenge than anticipated!

The wiring diagram shows to install the shunt between the Load(s) and the Negative battery terminal.
I'd prefer to install it between the Positive battery terminal, and the alternator & positive feeder wires throughout the chassis BUT exclude the starter motor.

If it is installed on the Negative side, then I can't really exclude the starter (the amperage from that would probably fry the shunt).
The sheetmetal body, frame, and drivetrain are all grounded together. If I somehow isolate the drivetrain (starter motor), then I also am excluding the ignition system and 4wd 'Touch Drive' unit.

Any ideas? Anyone know of a "positive shunt" Volt-ammeter?

Does the shunt have an amp rating on it? The stunts we install would fry if you ran positive through them. The smallest we get though are 400 amp rated. Which should handle your starter fine. I assume that the starter gets ground straight off the block. So eliminating it would be an interesting endeavor. Shunts are not that expensive and normally are universal to work with multiple meters. So you could always purchase a bigger shunt if yours isn't rated high enough.
