(ET) E16 excessive motor draw

[Dean Stuckmann <dstuck lakefield net>]

Hi,
I have and E16 that is drawing excessive power, overheats, and then kicks 
out the thermal breaker after about 20 minutes of use (D1 speed 7). It 
does not seem to be the motor or thermal breaker as I replaced them with 
ones from my E15 and it does the same thing. It has all of its speeds but 
there is little difference between speeds one and two. It will be at the 
green/yellow line running wide open in neutral. And draws yellow/red when 
in the higher ranges. This is the same tractor that had speed issues about 
a year ago with a blown diode on the small square card.

This started about 2 months ago. At first I though that is was a problem 
with the power use meter - but as weeks went on I noticed less range and 
then as of late - the thermal breaker would kick in. Could it be that the 
motor in in multiple speeds at once somehow? 

I’m thinking about installing the DCX-300ET controller instead of messing 
with the old stuff. Any one have a bad experience using this? Also I see 
that a Curtis PB-6 pot is a throttle option. Are there others? I would 
prefer not to have a separate fwd/rev switch and the keep the “normal” 
throttle action of pushing forward for forward and pulling back for 
reverse like the original setup. Anything out there like that?

And lastly, I noticed that my E15, E16 and EGT150 have between .5 and 1.5V 
at the PTO outlet (when nothing is plugged into the outlet). It even has 
that reading when the power is disconnected or in the case of the E15, 
when the motor thermal breaker is disconnected for a motor swap.  Any 
thoughts? Or is that something that is normal? I only know the basics of 
electrics but I don’t know where that would come from. Anyone else notice 
that? My I-5 does not show any voltage. 

Thanks in advance.
