Electrical - 96 M900 - Obscene screeching buzz & no juice - FIXED!!!!!

if it's working.

That`s the key.
The buzzing indicates it`s not.

greenmonster, thanks for clarifying.  I thought that was what you meant, but I wasn't sure.

Last night I pulled the relay from the connector harness.  I took a fine sandpaper and sanded the connection greenmonster was talking about until it shined - there had been some dark deposits there, but I can't say if it was enough to prevent contact.  To be thorough, I also sanded all the prongs that connect the relay to the harness.  Plugged it all back together -

same buzz, no juice.


Soooooo.... I went here next:

mine did that (made the high pitch buzzing) when I had dirty contacts on the battery cables. I'm guessing that resistance in the leads ment that there wasn't enough pull to make the relay work properly?

anyhow, cleaned the battery leads  (after checking relay) and all good.... 

I've got the battery out and on the trickle... I should have it in the green by tonight after work.  The + connector screw had some corrosion on the top of the screw itself, but not on the part of the screw that connected to the lead or the lead itself.  I've got the corrosion worked off the screw, so I'm just waiting on the battery to charge.

Stay tuned...

And w that done and the hood off, the relay clearly shuts on & off when ign is turned on-off?

I believe so.  The arm visibly moves into contact when the ignition key is turned to "on," and back when it is turned to "off."

OK.
Sorry it wasn`t that easy fix.

Update - It's up and running!  My neighbors are probably furious that I had to test it at 10PM local, but they can always move...

A day on the trickle seems to have done the trick.  When I picked the battery up and returned it to the bike, it was audibly bubbling.  It wasn't doing that before I placed it on the charger, so I'll guess that low spark was causing my relay to not close.  Looks like I'll be springing for a new batt if I don't want to ride in fear all summer... probably money well spent.

Thanks to all for the helpful advice.  Bacon for everyone.  Or beers if I run across you at the MotoGP.

good to hear! 
I think you probably dont need a new battery, just keep ALL contacts clean, your bike'll love ya!
