I have an A.C.L. MTH part number MT 2139...... vintage 1996 .......EMD GP20.... in "almost new condition".....that won't come out of hibernation. I am in the process of converting all of my PS 1 and PS2 engines over to BCR, and have almost all of them done. This engine is a PS 1...AKA Original Proto Sound. I have installed a good, well charged (Green) MTH battery, while trying to "revive" this engine. This engine has been stored for 15+ years....(in a climate controlled environment -- indoors at home) I was advised when I stored this engine many years ago, to remove the battery for storage, which I did. I have an MTH Z4000 transformer and have tried the reset # 18 feature, with no success. I have tried the MTH "Original Proto-Sound reset kit" (which I have) and with no results.....it just stubbornly sits there in "re-set" mode with the lights on, and an "idle" sound. I have brought to life many Proto Sound engines....PS1 and PS 2, but this engine is stuck in "re-set" mode, and won't respond!. What "voodoo" am I missing here?!
