       Lionel ZW transformer works great except one of the lights
       By: mtfrizzell Date: April 23, 2017, 7:24 pm
       ---------------------------------------------------------
       I am refurbishing a used ZW transformer. It had a bad cord, one
       bad ground terminal and no light bulbs.  I replaced all the bad
       components and tested the functionality. All throttle and
       voltage controls work as expected including whistle and
       direction.  The only issue is that the red bulb (left side) does
       not light. Swapping the bulbs proves both bulbs are good.  I do
       not see any bare, shorted or open wires. Does anyone have
       suggestions as to what might be amiss.
       Thanks,
       Mike

       The red light should be off, it's the circuit breaker light. If
       it does light you have a short circuit on your layout, possible
       train off the the track or something laying on the track.

       Interesting as nothing is joked up to the terminals.

       When I deliberately short a terminal to ground the red light
       does not come on. Concerned.

       The red light will not come on until the circuit breaker trips.
       If the breaker trips and the lamp does not light, then you
       probably have a wiring issue.

       If you have not found your problem, I may have. I have (had) the
       same issue. I thought it was the circuit breaker, I have a new
       one on order. But in the mean time I found this:
 (HTM) http://www.agtta.com/Tech-Tips/Tech-tip-ZW-repairs3.pdf
       Check out page 3. It talks about a bad resister wire. I did what
       they suggested, swapping out a 14 volt (I had no 18v bulbs) and
       running a jumper wire where the resister wire is at. All of a
       sudden my red light worked when I shorted out the system. I'm
       still putting in the modern circuit breaker when it gets here as
       I felt it took a little long before it tripped, but it did trip
       and it did light up the red light. Now I have to find 18v lights
       with the little globe as the ones I have are too big to fit in
       the red light dome.

       The 18 volt bulbs with the small globe (G3-1/2) are #1445 and
       available from The Train Tender.
