    Salty_monk, you had an 82 GS1100G. Where on the frame did you locate the SPG on that bike?

    The left side plate from memory. Somewhere down by the fusebox / ignitor. On my 1000 I use one of the now redundant airbox mounting tabs.

    I use one of the mounting posts for the starter relay.

    Many thanks to all have responded to my post by sharing your experience and thoughts. The borrowed multimeter confirmed your suspension that the fluctuating voltages were a result of a bad multimeter, Klein MM100.

    I followed all of your recommendations for checking and cleaning ground connections and adding a single point ground SPG to the frame. Located the SPG at upper bolt of the engine plate on the left side of the bike. Have new ground wires going to the (-) battery, SH775, and the bolt of the fuse box where a harness ground was also attached. Left the ground wire from the (-) battery to the back of the crankcase as suggested. The harness is also grounded at the factory location to the battery box.

    Rode the bike tonight. All the quick check voltages are within the ranges listed in the Stator Pages. Thanks again.

    It's always nice to get the pieces of a puzzle in the right position. I had a MOSFET fail in a Polaris regulator I was using on an 1100 and it did about the same thing. Congrats!
