A "Diode tester" is just the Ohm meter function of "most" meters. The symbol looks like this:

I wouldn't bother with light bulbs. You can get a decent tester for $15.00

Oh ok so I am good then.

I've never had one die shy of 4, sometimes 5 years.

Turn around is about a week with the guy I deal with so that may be that for the year which mean I will at least get to put more miles on the buell.

Check the stator

Another guy suggested checking the alternator so I will do that tonight since I need an extra pair of hands. So Iwill hold off till tomorrow before ordering anything.

Its called a stator. And you check it in AC volts. The diode (voltage regulator, also sometimes called a rectifier) converts that AC voltage to DC voltage.

Further, VR's can be tricky. I find the best thing... establish the battery holds a charge. Do the idle test of volts as you did at the battery. If fail, test the AC output of the stator and if it passes then the only thing left is the VR. Process of elimination. I have done it many times this way.

Thats prety much the direction I am going with all this, I am going to recheck the battery again today to make sure its still holding a charge. The stator I will try to check tonight since I need an extra set of hands to do that, but given the bikes reputation Iam leaning towards the voltage regulator.

A guy on af1 already offered to sell me one off of his old bike that hes parting out, not sure if I will go with that or just buy the aftermarket one.

I wonder how many R/R's and stators were ever replaced because the wiring/connectors were bad. Someone changes a R/R by disconnecting and connecting the wires. Then the battery charges. Was the R/R bad or did disconnecting and connecting the wiring fix the problem?

By the way, Aprilia Falco's are known to have problems with the sidestand safety switch, and they aren't the only brand with this problem. And it doesn't matter if the frame is steel or aluminum, the ground connectors always have corrosion.
