022switch problem

GG-1fan,

    Sounds like you have a bad piece of track going into your switch in the direction the Berk is having the derail problem, replace both track pieces coming in and out of the 022 and see what happens, also make sure the old 022 is screwed down correctly and not over stressed.  You could also have a short in the switch, however if the different

smaller engines cross the 022 correctly, it usually means your Berk being bigger and heavier is drawing power from an un-insulated track when it should not, causing the 022 switch to activate.

It sounds like the switch is not throwing the points over far enough and the pilot wheels are picking the points. Increase the voltage to the switch motor and/or perform maintenance to restore smooth, accurate, and complete operation.

GG-1fan,

   Rob makes a good point, if you do not have the required power to activate the 022 switch fully what he says can happen, however the way I read your post, it seemed to indicate the switch was activating as the Berk passed thru the switch.  If that is not then case, Rob's summation is right on the money.

Thanks for all the advice.  I tried boosting up the voltage on the switches as suggested by Rob and the problem resolved itself.  It seems that even though I have 5 switches that function well at a lower voltage, the one that is a problem doesn't unless I rev up the voltage for all.

You may want to tear that difficult switch down and clean the contact points, then lightly oil.  Dirty sliding contacts inside often the cause of needing higher voltage.

Sounds like you might want to give it a good cleaning as suggested, but how much more voltage is it wanting to see to throw right?.   

I have the constant voltage all the up on my ZW for the switches.

Well, that's probably excessive!  I'd stick with 15-16 volts, when you crank them up too high, the contacts start to get eroded.

I guess I'll have to take the switch apart or perhaps check the wiring connections to the buss line.  Otherwise, I will have to keep the voltage cranked-up which, as gunrunner says, can cause problems.
