Electrical question

[tommymac]

I have the futura shop manual so that should be in there and am 99% sure it is, just too lazy to go look right now

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.

NOW you tell me!

While you're at it, look up the test for the diode module (should be under the seat).

Ok found that in the manual is on the left side by the ecu. My volt meter does not have a diode tester in it so I would have to rig up abattery with a bulb to test it.

My 79 Suzuki had a separate regulator and rectifier. When they went, I got an aftermarket R/R. Still wouldn't charge, even though the stator checked correctly. That's when I took the ground wire from the new R/R off the frame and connected it directly to the negative terminal of the battery. Has been charging perfect for over two years.

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

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

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.
