When it's powered on by the z1000 it won't exit reset. I've verified this with 3 different locomotives that are all exhibiting the same problem. Is there something about a z1000 that's incompatable with some PS1 locomotives?

Yes, some (mostly early) PS1 locomotives will not exit reset if the output of the transformer is not a "pure" sine wave. The Z-controller is not a "pure" device, while the Z-4000 is "pure". Waveforms are discussed here, and here with some further discussion here, here, here & here. Also mentioned here, here, here & here, and probably elsewhere.

Three clanks mean that your PS1 engine is "dead" because the electronics are scrambled. Look up "three clanks of death" for more...
