Premier SD70ACE may be stuck in neutral

Carl, some information on your engine would help.  PS2 or PS3. Item number would help.  If you have had boards go bad before on this same engine, I would be looking at a chassis issue.

Give some information on the engine.  Have you done a DCS factory reset?  

Carl it would not do any good to call MTH for a board number, they will only sell boards to ASC tech's that have taken the 3 day course at MTH . you might try

the transformer conventional reset 1 whistle and five bells and if it resets you will hear 2 TOOT'S whistle blast,

AS Marty said to you earlier you need to give us the item number to be able to help you fully , otherwise it's hard to help you or anyone because the tech's do not know what exact engine you have and different engines have different issues!

could this be Product Name: SD70ACe Diesel R-T-R Deluxe Freight Train Set w/Proto-Sound 2.0

the one you have?

This one is P S 2

Pull and reseat the motor plug from the back of the board.

Hi guys,

My appologies, it's Item 20-202219-1 with PS3.0.  I have tried reseating both the plugs on the main board. 

Start up the engine and do a track signal strength test.  What number do you get?

The headlight flashing doesn't really sound good, but seems like everything works but motion.

When you press direction button does headlight go bright (rule 17) and when you press again does headlight go out, even though reverse light does not come on?

Hi GGG

Yes rule 17 lighting seems to work, also goes brighter when you increase the throttle but of course no engine movement.

I now have 2 boards with exactly the same problem, I tested a good board from another engine in the SD70ACE and everything including motion works fine, but the two faulty boards all give error "Unable to read EIS fields - Incorrect response from command" when trying to write flash file to engine, but writing sound file to engine runs through the whole process and engine starts up.

Would you guys think these two boards are faulty or stuck in some neutral or direction mode?

eOh yes I get 10 out of 10 signal as I have a dedicated programme track connected with very short wires directly to the TIU with nothing else hooked up when I do these tests.

The only way to tell is trying to unlock them with a conventional transformer with bell/whistle.

The resets with DCS did not work?

Not sure why you can't load the flash code.  Boards may have to be tested by ASC tech.  G

Ah, we found a possible cause, a bear piece of wire, one coming in from the bogie/truck, of about half an inch long and possibly had touched the chassis at some point, it was hidden under the dcc/dcs and 2/3 rail switch stand.  Now this means most likely these two boards have something burnt?

I don't know if MTH will come to the rescue after I managed to get them to send me the second board, but admittedly this engine had issues since the start, hence I'm not sure who and what the cause of this bare / frayed wire was.

I'm prepaired to mail both these boards plus two other simlar boards from previous engines but those are totally dead, to a willing or qualified tech in the U.S., as we don't have anyone willing to touch O gauge MTH in South Africa, that I know of, and I'm willing to let a willing techn see if he or she can get at least one of those boards working, if only reset in conventional required, well then great, and I then only want one working board back., or else at a repair cost take 2 boards back and have one spare.

Can anyone on here help?

My e-mail in profile, I can do these for you. G
