Thank you so much for the speedy replies.
VERNON: Thanks for the component fix, and photos of the alterations to the internal circuit board of the Z4000, but this is well above my paygrade. And I now realize there will be an awful amount of heat generated by a resister, and that will definitely become a fire risk. We won't go down that slippery slope!!!
I will try the brake light bulb trick tomorrow. I have some brake light bulbs for commercial trucks that run a 24v system, so they should work fine......yes?? I'll let you know the results tomorrow.
BRUCE: I'm interested to know more about this "thyrister" thing. Can I purchase it from my local electronic supplier, or is it a "special order" thing? Does it get installed externally on the variable terminal posts of the Z4000? If it is a standard off the shelf component, can you tell me the code number/identification label etc. so I can see if the boys here can supply me with it.
Also, thanks for the suggestion about hooking-up a Z1000 to the fixed output of the Z4000, and using it to run my trains, but that was the whole point of the exercise in getting me a Z4000. I want to dispense with the Z1000 and use the re-programming buttons on the Z4000, as well as the special MTH hand-held remote that works in conjunction with a receiver that plugs into the Z4000.
