Re: (ET) Lost all forward speeds on E12

Bill Gunn said that one of the two coils (1F or 2F) on the lower control panel has failed.  He said to take a volt meter and test both the small and large terminals on each.  If couldn't remember exactly what to test for, so I just wrote down my results and called him back. 
    Small terminals on 2F read zero in neutral and 37v when throttle forward.  Large terminals read zero in neutral (I think) , zero in forward but 37 in reverse.  He said this was as it should be.
    Small terminals on 1F read zero in neutral (I think) and 37 volts when throttle forward.  Large terminals read 37 volts in neutral AND 37 volts when throttle forward.  This last result he said was wrong.  Apparently, large terminal should have read zero in forward.
    So this indicates that 1F is needs to be replaced.  I ordered a new coil, part #OP631 at $90.27 with shipping.  I have a used coil around but I am not sure if it works.  If I have time, I'll install it and see if it solves the problem and use the new one as a back up.  The new one is a different design, a kit, Bill said he changed to keep down costs.
    Hope this clears things up.
Very sorry to hear that Bill is closing down.  Things will be a lot harder without him.
Thanks for your advise and help.  Will let you know when I replace coil 1F and how it worked out.

Zack,

What did you learn from Bill Gunn about your relay setup? 

I forgot to get the part number when I was on the farm yesterday, sorry.  but here's what I find on the hosfelt.com site this morning.  I'm not sure that DPDT is what I used I think it might have been SPDT.  Obviously I am not well versed in electrics!

go to www.hosfelt.com and in the search box put in this part number: 45-608 or you could simply put in relays and browse through their inventory.  The socket might be part number 21-364 but I can't be positive because I'm not getting the picture of it in my browser for some reason.

sorry I'm not much help here,  but let me know what you find out from Bill G.

It sounds like a "welded" fwd/rev relay to me.  It's located 
behind
the "firewal" under the hood.  drop the firewall down by removing the 
4
screws (cover the batteries first!) then move the throttle from rev 
to
forward.  you should hear a click and see the relay move.  My guess is 
that
the relay points are stuck in the rev position.  if you are lucky you can 
get
them apart, clean them up and use again.  Last one I bought from BG was 
$20
I had this problem so bad that I put in an inline fuse to protect the 
relay
(now I blow fuses right and left) I also found an equivalent relay 
($2)
(Hosfelt.com) with socket that makes it a whole lot easier to change 
the
relay and give it a secure 
mount.

good 
luck,

I've seen this.  The round black plastic disc that controls 
the
speeds is worn.  The disc engages micro switches that control 
which
contactor closes; that's why you get the reverse speeds.  
Forward
gets more use and wear than reverse.  Try bending the mount for 
the
forward direction micro switches a fraction of a millimeter 
toward
the black 
disc.

Had problems a few times with moving the throttle forward 
and
getting no response or a quick jump in the power usage needle 
but
then nothing. Now I nothing at all going forward but reverse 
works
fine.  Had to finish yesterday's mowing in reverse only. 
Also
previously the throttle was jamming so a drop of lubricant on 
the
controller by the first switch solved that.  My guess is that the 
first
switch became worn or damaged by my pushing past the jam (before 
the
lubrication).
Would the first speed switch be enough to account for the loss of 
all
forward 
speeds?
I have an old controller (for parts) and guess that replacing the 
first
switch might be the way to 
go.
I am a complete novice and am just trying to go on common 
sense.
Any advice from someone with experience would be greatly 
appreciated.
Thanks,
Richard "Zack"
