Sorry Slag, i think i sent an email to you on accident just now.
Okay
Testing from (-) batt terminal to R/R makes the meter to crazy.  To unpainted areas of bike is stable <5 ohms.  And I'm not sure what you meant by "negative side of lights on bike".  Does this indicate a bad connection of RR to bike?  Also, I think I found the diode setting on my meter, I'll read thru the previous posts in this thread for whoever told me about that test and try it out.
Thanks Slag

Not sure what the issue is, but the negative terminal of the battery is
"ground", and it is connected to the chassis of the frame of the bike, hence
the term, "negative ground system", as the negative battery terminal is
connected to the vehicle's body/chassis/frame; if the positive battery
terminal were connected to the body/chassis/frame, it would be a "positive
ground system"...

To check the grounding of the system, connect either DVM terminal to the
negative battery terminal, and touch the other terminal to various points on
the bike to verify a good ground connection:  the R/R outer metal case (<5
Ohms, if connection is good); body frame of bike (unpainted metallic point);
negative side of lights on bike; etc.  Cheers!
