Reply to "railking remote lock-on item no. 50-1013."

Resurrection of this post, funny enough. I just purchased one of these off of eBay.

For those who know more about this circuit, I'd like to learn a bit more.

It was working great until a wheel short across the track (which tripped the MTH Z750 4 amp breaker) and then I'm in the same position as alot of these posts.

It acts as a pass through for a full 21V AC to the track.

Those Power FETs (or are they Triacs?) That usually go bad I've seen some datasheets of variations of them be tolerant up to 21-30 Amps...

I'd find it hard to believe that little lock on saw that much, or maybe a less current tolerant part was selected. Either way, any other common points of failure in this device? I have a new one on order, but might want to fix this one.

Does anyone have a schematic?

John & Stan I figured you two might know something 😀
