This is a more specific continuation of this thread: viewtopic.php?f=4&t=54893#p506371
The flickering may have started after I had a parking lot-style drop: I had been riding for a few hours on back roads, pulled over to take a break. Was stopped, engine running, put my feet down, right foot slipped, bike was 90° on it's side and I was hands-and-feet in the gravel. Bike ran fine after getting it upright, didn't notice any flickering, but wasn't riding at night either.
I'm having issues with the headlights, running lights, dash lights, etc. flickering. Seems worst at low RPMs and when the bike is cold (maybe the first 10 minutes of riding).
I've also had the electrical quit once within that first 10 minutes: the scooter stuttered/lurched, every light on the dash went on (lots of indicator lights!), every light on the bike went out, then the bike started back up. That happened leaving the parking garage and the bike was fine getting me home, but I've not dared ride it since (imagine that happening at 70mph in the fast lane on the highway...).
The weekend before this "sudden stall" happened I brought up the flickering lights with my mechanic and he checked the electrical. The R/R is apparently failing (voltage is low...he figured I'd be okay to ride until it came in). However, he says the flickering may not be the R/R but a loose connector. He suggested since the fall hit the cowling hardest, to take it off and check all the wiring (still need to do that).
Per the link above, I have the battery tray off and checked what I believe is the frame ground connector: white plastic socketed connector (single blade), one end leads to negative terminal of battery, the other end leads into the wiring harness on the left side of the bike. Looks fine.
--While I'm in here, anything I should do to the frame ground connector as a maintenance item? Blade contacts look clean and no black marks or any indication of a short.
--Any multimeter tests I can perform?
--Anything else I should specifically look at while I have the battery tray out?
--Anything under the front cowl I should look at specifically?
--Do you think it is, or is not, simply the R/R?
