Re: (ET) Clicking contactor and blown Controls fuse - Early model E15



    OPEO must have recognized the error of their ways. The E-15 HA and later had a much less complex arrangement.

    Take a look at it in Homeowner's Manual. :)

I had more trouble with the reverse relay than anything else on my E15.  The 
final straw for me was the snowstorm where I was plowing the driveway with 
the hood open and the panel unscrewed so I could push on the reverse relay 
to make the tractor back up.  

Adding a modern solid-state controller markedly improves the tractor's 
manners and reliability.

The downsides of controller conversion are 

1. You gotta pick (relatively) cheap or (relatively) easy.  You can't have 
both.

2. Unless you're a well trained up-to-date electronic engineer, the 
controller becomes an unfixable black box to be sent out for service or 
replaced if/when it fails.  Fortunately, that normally doesn't happen very 
often.
