Mth EP5 PS1 2 bells and wont move

You did a reset 18?

What happens when you hit the direction button or what sounds does it make?

PS1 engines won't leave the initial startup (rest mode) if the voltage is too high. Typically you'll hear a single bell sound when this happens.

I have a Mth Premiere EP5 with PS1 and when I turn power on to the Engine I get 2 bells and loco doesn't move. I tried a reset with a z750 pack and it didn't help. The battery is just over 9 volts. Does anyone have any ideas?

PS1 engines need to see 10V max at start up. Higher voltage puts them into reset mode.

I learned the same lesson the hard way too.....

ProtoSounds® is equipped with a microprocessor, that, depending on the
amount of memory it is allotted, allows the user to utilize several remotely
activated functions. In the simplest terms, ProtoSounds® has its own
“Computer" controlling these functions. In fact, the power of this
microprocessor is the same as that of a 286 desktop computer! In order to
access many of these remotely controlled functions, the user must be in the
RESET state to do so. RESET is entered anytime power to the locomotive
has been off for more than 3 to 5 seconds. When the engine first enters
RESET, the microprocessor initiates a system check to determine if the
system, transformer and engine are operating correctly. This takes
approximately 2.2 seconds during which you will hear the engine’s startup
sounds begin. In order for ProtoSounds® to properly initiate the system
check, do not advance the transformer throttle past 10 volts when you first

enter RESET, wait for the diesel startup sounds to begin and then slowly
turn the transformer throttle to the off position and then back on again to
enter the forward phase. Interrupting the power too quickly may cause the
system to re-enter RESET (signaled by two dings of the bell). Should this
happen, wait longer before interrupting the power to enter the Forward

Two bells suggests it's not going into reset mode as that would result in a clank.

I think it's hard to get the voltage correct with some Z750 packs. They seem to go up fast, or at least the ones I've tried. (maybe 2? old used ones... )

From my personal experience with PS1 boards (there are early boards and later boards) the early boards are very very finicky getting them out of the 'reset' start-up phase.

The only way i could get mine to work was with my Z1000 transformer, and treating them "gently" when dropping the voltage from 10V.....SLOWLY!!

Could not get them to leave the "reset" phase using the Z4000 (2 bell rings)....BUT...I have a couple of these older PS1 locos that DO leave the "reset" using the Z4000....if I keep the voltage as low as the Z4000 can manage (around 5V) and hitting the DIRECTION button. Go figure!!!

Good luck Shurlock 1 !!!

So you could move through the reset stages getting clinks and clanks?  If you power it up and have idle sounds.  Turn off power.  Does it play shutdown sounds?  If not bad battery, harness or battery circuit.  G

Thanks every one. I Have to get out my z400 and try a reset.

shirlock1: Please let us know how you get on.
