Hi Guys.....
Well....looks like my Rev L TIU is either failing or has failed.
I was running 3 trains on Saturday just fine.....no issues.
On Sunday when I turned on the main power switch (the 4 PW ZW transformers and TIU are all plugged into the same switched power strip):
1. Two PS3 engines immediately took off like bandits (the Var channels are set to Fixed and the ZWs are all set at 17 volts). This prompted an immediate power shut down at the power strip,
2. One PS2 steamer was not responding to commands,
3. One TMCC engine seemed to be responding normally.
I had to do a conventional reset on the two PS3 engines using a separate MTH transformer....they were both stuck in forward.
Everything was powered down and the engines were put back on the track (one at a time separately) and powered everything back up.
When Start Up on the PS3 engine was attempted, the "Engine not on Track" message displayed.
An Engine Reset was done followed by engine Start Up....same "Engine not on Track" was displayed. This was attempted for both PS3 engines.
An engine Factory Reset followed by attempts to Add the engine was attempted. No luck....got the message "Engine not Found". This was attempted for both PS3 engines.
Complete resets of the TIU and remote proved fruitless. The same results described above were experienced for all MTH engines.
The Rev L TIU was replaced with a Rev I. Resets of the TIU and remote were done. The same engines above were successfully added and are successfully running.
Sigh..........I think the Rev L is toast.
