Re: (ET) Re: Parts NOT needed -- cautionary tale(s)



A big truth: When you're working inside the box there, TURN THE MAIN CONTACTOR OFF!

Simple solution to keep things from exploding in one's face.

The problem did actually trace back to a faulty connection on my relay, as 
one
astute list member pointed out.  One of the wire connections physically 
broke
and the wire pair was just dangling free.

However, it was when I was poking around in there, that I caused the major
problem (and melted 2 contacts & blew a fuse, but that's another story).  
When I
was fiddling around with the wires, trying to crimp on a new connector for 
the
broken wire, I accidentally (read that as "my 4-year-old must've distracted 
me")
wrote down the connection diagram backwards.  Instead of writing down that 
the
front and middle connectors were used, I wrote down the back and middle
connectors.  I had the wire numbers in the correct locations, I just got 
the
back and front rows mixed up.

Anyway, when I reconnected the wires, no motor action.  By then, I had just
about given up (thought I'd fried something) and decided to buy the Alltrax
controller and be done with it.  But, happenstance caused me to sit on the
problem for a while (that and I had to take care of my 4-year-old alone all
weekend long), and here, today, I had a thought, maybe I connected 
something
wrong, let's go see.  Well, sure enough, with all wires correctly 
connected,
full operations of every system was restored.  Sorry Alltrax, not this 
year.

Problem #1 turned out to be the #28 wire broke off the bottom of the relay
(sometime last year), and I hadn't noticed.  With no #28 wire, the only 
way it
would work is if I kept the relay pushed in, and I zip-tied it to jury-rig 
it
through to this Spring...but that prevented cutoff in a braking event, so 
pretty
bad.

Problem #2 was I put the wires back on wrong after I fixed problem #1.

Problem #2a was, again my 4-year-old distracting me, with the power on, I
touched one of the wires to the finger of another relay and *TZAP*, blown 
fuse
and another new connector.

Moral of the story, don't have distractions around when you work on your 
tractor
and observe proper electrical safety, ala Al Borland, NOT Tim Taylor.
