Dead Trumpet



Hi Gang,

Paul Reyes has been helping off line, and I'd like to see if any one else 
can help me trouble shoot.

Here's the problem ---essentially the bike just died after 2 weeks of 
straight riding on a cross country trip.  Pulled over to look at a map, 
shut it off and it wouldn't start back up.

Now its back home, torn down, cleaned, etc. ---- I've done a number of 
diagnostics, having just learned to use a multimeter  (my command of 
electrical and electronics is very limited).
The battery was tested and found the be bad so I replaced it.   NO HELP
I've checked the kill switch, starter switch, clutch switch, and side stand 
switch --- all of them give a full scale reading on the meter indicating a 
closed circuit.   The cutout switch for the lights works when I press the 
starter switch, but there is absolutely no movement of the starter 
motor.  The full pump comes on when the ignition is turned on (also part of 
the starter circuitry).

I've tried testing the starter solenoid, but not sure I'm doing it 
correctly.  With the meter set on 50 DC, I get a deflection equal to the 
deflection when the leads are placed on the battery.

I've checked all of the fuses.

Before having to give up and take it to the Triumph dealer, I'd appreciate 
any input (including specifics of how to test for it).  It seems as though 
it has to be something simple that I'm overlooking.  The bike ran 
perfectly.  No indications that it was going to stop.  I've   only got 
12,000 miles on it and never had any problems.

Any help would be appreciated.
