Re: (ET) E16 drive issues.



I would inspect/verify the Field circuit. The diodes, the FW Relay N/C contacts and the wiring. Lotsa current and no GO is a hallmark of weak or missing field current.

Hi,
Having some issues with my E16. Once in a while it would make some rapid jumps 
between what seemed like speeds 1 & 2. In rare cases the load was heavy 
enough to drag down the mower deck as well. And once in a while the motor 
would not turn on again, but I could hear the relay clicks like it should go.

Then it lost forward but reverse would still work. Now there is no drive 
at all but again the relays all click. So I started checking things and 
found that there was 36V across the armature in forward and reverse. The 
book says to replace the motor so I started trying some motors out of my 
parts tractors.

Motor one worked in reverse but had issues on forward speeds. Took the end 
cap off and saw that one of the brushes was cracked and melted the holder.

Motor two ran great in all 3 reverse speeds, but in even the slowest 
forward speed the motor started at a dead crawl and continued to keep 
speeding up to a runaway condition. (The original motor never runaway) Is 
that another motor issue? Or do I have controller issues?

Thanx for your help.
