My E15 reached the point where it seemed that every other time I took it 
out 
something in the control system broke, went intermittent, or just plain 
got 
flaky.  Unscrewing the panel under the hood to replace exploded caps, swap 
out inexplicably broken diodes, wiggle the connectors on the boards, or 
try 
yet another application of contact cleaner gets old fast.  

Then last winter I lost the reverse relay (again) and for some reason the 
spare I'd gotten from Bill Gunn a few years ago wouldn't pull in without a 
physical nudge from a finger.

Having to plow snow with the hood off and the panel loose was the tipping 
point.  Ripping out the whole rat's nest and dropping in an Alltrax 
controller took care of the control problems once and for all.  I heartily 
recommend it.

     I believe in an America where the separation of church and state 
     is absolute ... where no minister would tell his parishoners for 
     whom to vote, where no church or church school is granted any 
     public funds or political preference ... where no religious body 
     seeks to impose its will ... upon the general populace or the public
     acts of its officials.
