What happens when a starter is fully engaged and being spun by the engine. I remember this causing something similar.
Could you please explain this? I was thinking that the starter motor would be acting as a too-fast generator, creating a reverse EMF on the system.excessive current draw

How does one test the shunt to see if it is cracked or if the cable is not well connected?. . . the shunt could have a crack causing the amp fluctuation.

I’ve heard if you tap them with something metallic and they don’t “ring” then they’re cracked. I give mine a gentle tap every time I’m under the panel and have always heard a ring. Mine is working fine, but I’m not the smartest electrical guy. That test may not be worth doing.
Never heard that one. It's usually visual or olfactory. Look it over on installation and it should be good for life. If it does crack at a later date, you'll smell it.

Look at it.. this one took a hard ground and was sending all battery current to the main bus through the ammeter and back to the other side of the shunt than to the bus.
