electrical woes

[chopper]

Hi everybody,

I am trying to figure out what happened to this '97 M900.  I had the bike torn down and put everything back where I found it.  Put in a new battery and checked the electrics.  Everything worked great until I pushed the starter button.  It tripped something and now nothing works, I mean NOTHING!  I have full battery voltage at the red wire to the ignition switch when the key is off.  When I turn the key on it drops to 1 volt and no power at any of the other 3 wires.  No power at the fuse box with key on or off.  I am thinking that the switch is bad.

Any ideas???

Check the main fuse...

it's like 30 or 40 amp and is right next to the battery

Sorry to threadjack, but what exactly does that main fuse do?  I removed mine the other day while trouble shooting and the bike still turned over.

The main fuse is fine, as are all of the others.

Try jumping the bike with a known good battery first.  If that doesn't work check for power at terminal 85 at the main relay with the key on.  Make sure the kill switch is in the run position.  Power at terminal 85?  Ignition switch is good.  Now jump 30 and 87 with a wire of at least 14 gauge.  The bike starts now? Faulty relay.
