Anyone had problems with new generator cutout relay?

Long story short: I bought a new TISCO cutout relay. After it cuts in, it won't cut back out until battery current is disconnected. Seller sent me another. It behaves the same. I have two old cutouts that work fine (and were in use). Experimented on three different tractors, new cutouts won't cutout, old ones work fine. Is this a common problem with modern relays? Is this best forum for the question. Thanks.
 
Too much of Tisco"s stuff is China built junk. I have found about half of the electrical stuff is bad to start with. I refuse to use Tisco supplied parts anymore. If I fix it and the junk parts fail I get the blame. You have to watch the parts you get from NH. Some of it is Tisco sourced.
 
If it has a removable cover, it may only need the cutout voltage adjusted up a bit. Just need to adjust the spring tension up a bit.

B&D's solution is best, to replace it with a diode.
Solid state beats a mechanical switch for reliability.
 
A good idea...replace it with a diode...but how
and where,(in the circuit) Please suggest a diode
part number and rating, (volts + Amps) and a
drawing of how to wire it.
 


Id call my old friend Jim at Agri Services in New York www.wiringharnesses.com 716-937-6618. He sells the fake solid state diode cutout relays that WORK. Tell him Ol John T says hi

Yes, it is a common problem with new, foreign-made mechanical regulators. Soft contact points that arc and stick together.

I recently bought three new ones in a row, from through this website - for a Ferguson 35 Deluxe.
Equivalent to a Delco 1118981, 1118988, 12336883, etc.

First two stuck something awful. Cut-out would stay "in" until I popped the cover off and pried the points apart. They were very poor quality. I know one had a the brand name of "Arrow" on it.

Finally, they sent me an A & I replacement. It is built much better and has been fine. I still isn't built near as heavy as an OEM AC Delco, but close enough and works fine. An OEM AC Delco cost over a $100 now.
 
Go down to the junk yard and get an old regulator from a car or truck.You can use the cutout section to replace the small cutout,
