Update, and a few questions.
The battery did seem to have a failure. No warranty on my $100 agm battery from autozone that was less than a year old. Ended up buying a cycle gear standard battery with a lifetime warranty....I dont get that one, but hey, I will abuse it to the best of my ability.
I replaced the battery, but am still getting the "turn over turn over turn over, click click click click, turn over turn over turn over, click click click" thing. Today I got the bike apart and dont see any corrosion on the battery cables and didnt come up with any crazy resistance numbers. All connections are/were tight. Am kinda looking at the solenoid as the problem. Will do a clean up of all the cables and reassembly as part of my testing before I look at replacing the starter/solenoid (probably try to find a used one).
Of course I came across snowbums site http://www.bmwmotorcycletech.info/boschvaleostarter.htm
good info, but dont see anything on how to bench test my starter. I dont want to make my situation worse. Anyone know where I should be putting power to test? Pos to pos, neg to housing, and then just pos to the other lead?
