  I was careful how I worded it but  there's always someone ready to  
jump on it ... when it failed, the entire remainder of the relay arm  
literally fell off, but when I looked the pieces over and held them  
up to where they had been attached it was amazing that the arms had  
many any contact at all as the ends were worn down a lot as well. So,  
my statement stands, it was amazing that it worked at all during the  
week before it failed! Now, Wes, go sit in the corner for an hour!

  cheers ... BBR
