Re: (ET) Interesting.....



I found that the switches had gotten a fraction shorter from decades of 
ware so I took the throttle switch out and replaced all of the the micro 
switches.   Be sure to test each in all 10 positions since there is just a 
little slop. 
5 years later I'm down to figuring out why it doesn't get past 3rd or 4th, 
but occasionally does after 30-45 minutes of constant run. 

Also Guessing either censor connected to the motor, connections to the 
main board ( only 2 year old) throttle switches alignment or one of the 
relays.  Just have to get the shop Manual  out and "shoot" a weekend 
trouble shooting the problem. Luckily I may have enough donated spare 
parts.  I think the major design flaw is the method they used to connect 
the leads to the board. For the old board I drilled holes at each tab and 
soldered a harness to it.   Problem was closing the compartment making 
sure nothing was hitting bumping into the extra wiring. 
Just too tight in the top compartment in general. Even with new contacts 
on the new board with hours of adjustment for a nice snug fit for each. 

Bottom line, the care of these machines is a hobby onto themselves.  Got 
to love the final little successes that make you feel that they out way 
the hours head scratching & pinched fingers, etc.
