I checked house voltage on several occasions at different times of the day and I get 124 +/- 1 volt. The power supply unit for the command base is giving me 12.4 v consistently. I even left it plugged in for a while to see if it changed when it was hot. I don't know how to check the milliamps.
Is there anyway to trouble shoot the command base units to see what is damaged? That may tell where the problem is...or maybe how I can fix them???

The BASE1 has a single binding post that connects to the outside track. Inside the command base is a .1 capacitor between the logic and the track, pretty effective protection for a wiring screwup. Short of plugging something really wrong into the power jack of the BASE1, I fail to see how you commit a wiring error and toast it. Of course, you could connect AC to the serial port, but that's another story.
Maybe I am missing something...I assume that the 3 base units are bad. The red / green lights don't come on and I can't control TMCC engines. Each time I put on a new one I tried to check to see what I might have hooked up incorrectly. I now have the Legacy 990 hooked up and I am able to control my TMCC engines with no problem. I have checked each track separately to see if there are any bleed overs of power from one to the other. Also checked accessory power to see if that was the issue...nothing. I have 10 amp fuses on all the power lines. I have my DZ-2001 back from Dennis and I am going to connect it to one leg of the Y cable since the Bridge is connected to the other leg so I can control my TMCC powermasters. I will then begin connecting my accessories to the SC-1 and SC-2s and should be able to control them through the CAB-2 also??
The only thing the old TMCC base does that you can't do with the Legacy system is control the old TMCC PowerMaster boxes. You'll have to add the Legacy PowerMaster Bridge if you want to use old PowerMasters.
