Re: (ET) Dead on the road



If the previous troubleshooting ideas don't pan out.....

Try checking the metal shunt that is behind the panel in front of the
shifter, in where the contactors are. Pay attention to the connections on
it, the may be corroded and weak.

Maybe the C-185 doesn't have one, I don't know. But I do know that there
is one on my I-5 and when it's contacts got bad it displayed the same
symptoms as you described. This differs greatly from the no field
error.... The no field problem is high current - low power - low speed, 
while a bad shunt will exhibit low current - low power - low speed (feel
free to substitute low with no).

I first noticed my problem last year while plowing snow, everything worked
great for awhile, then it just went dead. I checked breakers, fuses,
battery connections(which will do it too, you didn't say you checked them)
but, after it cooled off a little it came back on and worked ok. Happened
a few times throughout the winter, very frustrating. It's damned hard to
troubleshoot intermittent faults.

So this past summer it did it again, only this time it didn't reset. THEN
I found the problem, my connections on that metal plate shunt were rotten.

It was FUN to replace, I'm sure glad it wasn't winter....  ;-$
