I have a Lionel "NPR LEGACY Light 2-8-2 #587" 6-84532. i recently bought a z4000 transformer. I found online that 99% of people say that transformer should be compatible with everything. I even had the lionel service/dealer that i bought the transformer from show me it running a legacy engine in conventional.
when i try to run this steam engine in conventional with the z4000 two things happen. 1: if i try to start the engine from a crawl to simulate real startup behavior the engine stalls and the cab light starts flashing continuously. (it doesn't stop at a particular number of flashes to indicate problem code). the only way to run it is to start out at 11-12 volts. 8-9 volts and it stalls. 2: the smoke unit doesnt function properly. i can see a feint puff from time to time but that's it.
so i hooked up a cw80 and everything works perfect. bellowing smoke, no trouble with startup.
i cannot find a lionel compatibility chart anywhere, does this mean i managed to find an engine that is not compatible with the z4000 but is with the cw80 of all things?
