First off, and.not a problem, but I noticed the position of the handles. Is one at full power and.the other off? Normal KW handles both swing clockwise to on. A very very rare version, they work towards you off, away for on, in opposite directions. If thats the case it should be documented asap as.it is unconfirmed history.
You may need.to clean the track pins and holes on old track.
Look at Menards home improvement online. They have new full O track at reasonable price. Adaptor pins will mate it to 0-27, though there is a slight difference in height.
The simplest way to begin would be the meter. If its an ohm meter too, switch to ohm and.check for a short between center & outer rails. (Diode works too, many will beep on a connection in diode setting). Do this with the lock-on off the track. Press around on the center rail where the train stopped. The insulating cardboard may be bad. Find a shorted one? I bend tabs up and slide a piece of shoe box or similar in there.
You also have extra track. So put the lock on a piece or 2 of extra and see if the issue moves. If it does, remove the lockon and insert a wire into the track pin holes and test again. You now know either the lockon is bad, or the KW has a new issue.
Process of elimination by pulling and replacing a few peieces at a time will find the track short if its intermediate (off and on issue occuring randomly)
That KW is a good transformer, lots of amps. Too fat a wire is better than too small a wire. An old extension or power cord will work if you are on an extreme budget, but thats rather large and may need a few strands removed from thd end to fit a lockon. You can also solder wire right to the track since you have extra. A soldered connection leaves little doubt its a good connection.(use the outside of the outer rail, or bottom. Center rail doesnt matter).
I got unexpected company..Ill be back..
