Re: (ET) E12 speed control problem resolved



Start by checking to see if the L contactor gets power on it's coils when you put it in speed 1. If not, check to see if pin 6 on card 1 is getting 36 volts, then work it from there. There's a whole manual of testing you can do to isolate the problems.

I have a totally new mission effecting failure mode on my E-15, 
specifically, when applying drive power I get no response other than a 
click from somewhere below and 2-3 sec later another click. Both relays 
have been replaced and no change.
Any thoughts would be appreciated.

The speed selector / F-R control handle came out in my hand last winter.

The issue was the drift pin (roll pin) had rusted out.

I couldn't find a matching size piece in my tray of assorted roll-pins, 
but I did have a cotter pin which was perfectly matched to the holes in 
the arms of the handle.

Anyway, all reassembled now and working fine, so snow plowing capacity is 
back on line for winter 2023-24.

Contact cleaner for the E15 control board edge connector should arrive 
late today.

I remain constantly grateful for this list and those that contribute to 
it.  I'm a long ways from Elec-Trak heartland, and my two working electric 
tractors still functional almost 50 years after manufacture continue to 
astonish those who encounter them.
