39' 9N cut-out relay problem

The cut-out relay sticks when I shut off the ignition, causing the battery to back-feed back to the generator which is a dead short.

It is a brand new relay. I have filed the contact, which worked a few times. If I idle the tractor down before shutting it down, which slows the generator, it helps, but, it still shouldn't happen.

Is there something I can do to prevent this?
THANKS!

Let me start by saying I hate cutout relays. I went through three of them on my 2N in a month, none of which worked. The last one did exactly what you say yours does. My solution was a light tap on the case after I turned off the tractor.

Dell advised I try the after market regulator mentioned below. I put one on my 2N about a year ago and have been happy - very happy - since.

It is a true regulator so it is good to your battery. I have a 6 volt pos ground with two headlights, tail marker lights, and rear worklight. I run with all of them on while plowing snow in the winter. Not a problem with the regulator in place. Before the regulator, I had about an hour of snow plowing, then back to the garage to charge the battery.

Take a look at the website linked below. Also available from the web page is a link to the installation/operating/adjusting instructions.

Have you checked the generator output to see if it's overcharging and toasting the cut-out? funproducts.com has a look-alike that is a true voltage regulator if you'd want an alternative to the stock cut-out.

Are you sure it's wired the right way? If it were backwards, the relay would stay pulled in after you turn off the engine.

Otherwise, the solution would seem to be getting a new one.

Weak spring or wired in backwards will do it.My 36 ford still has the original Ford cut out on it.Must be 70 years old.A spring opens points when the engine stops.If you have cut out backwards the battery will hold the points closed and discharge thru the generator.
