So I recently acquired an older MTH model. I'm guessing it's early to mid 90's vintage. The locomotive is an MTH Premier EMD GP-9 (Cab #139). Locomotive comes with Protosound and DCRU Electronic Reverse Unit with Lockout by QSI. So, when the engine is started, sound sequence kicks in as well as lights come etc... Only issue is that it won't come out of neutral. So the research online tells me that it's probably a battery.
I replaced the battery and let it charge. Still nothing. So I'm thinking maybe the board is "scrambled"? I found this post on another forum that says the MTH Z4000 can reprogram the board/chip. Here's a quote from his post.
"If the engine doesn't give the three clanks of death on start up , it isn't "scrambled" and the force chip won't really fix what's wrong. The unit is probably stuck in neutral and the only way to unstick it is to reprogram the unit so it isn't in neutral. If the shop is nearby AND they have a Z-4000 this can be done in a few minutes. The 4000 can read the unit's "state" and can be programmed very quickly. You should replace the battery, probably with a BCR to avoid this issue in the future.
PS1 used a "STATE MACHINE" technology to program/access features. Unfortunately it needs a battery to keep track of the state. Worse, it requires about 3 seconds for the loco to come up and leaveprogram mode at start up. ANY voltage swings or DC offstes will be interpretted as programming commands and will probably leave the system in a confused state."
I have an MTH Z4000. Does anybody know hot to do this? I'm hoping this will fix my problem. Any and all help appreciated!
Ps.. I don't have any other MTH equipment than the Z4K. I run Legacy at the moment but am thinking about adding the MTH command and control to my layout as well. Not sure if any other hardware is required.
Pss... After charging battery for a couple of minutes at 12 volts, the engine continues to produce it's sound and run its lights for a good 10 to 20 seconds after turning off the transformer and completely killing all track power. Is this normal?
