Re: (ET) E15 Alltrax died

[Tom G <wavetech superlink net>]

Correct me if I am wrong but going by memory.
#1 the blower is a series motor not PM.
#2 Is it not hooked up via a contactor so I guess it is possible for a
spike to develop from the contactor when shut off.
I would check with Alltrax to verify proper hookup and weather a spike
from that contactor is enough to cause a problem.

To all you guys running with the Alltrax controller.  The first time I went to blow snow with my new (to me) rebuilt snow thrower my Alltrax died.  After two years of mowing an acre a week it seems odd that it happens the first time I ran the blower.  Everything still functions on the tractor but there is no life on the Alltrax LED and no signal to close the main contactor.  I swapped the Alltrax and everything is wonderful, but I do not want to smoke another. 
 
Question is, does the snow thrower generate a voltage spike when shutdown?
The power cord only has 2 wires hooked up to the drive, should the third be used ala the mower drive?
Should there be a clamping diode in use?
 
Thanks to whoever knows.
