Cant Add same engine anymore

It sounds like you have a failure on the circuit board of the engine, or very bad wire connections/dirty tires and wheels.

The number provided did not come up.  Is this PS-2 5V or 3V?

I assume the engine is running fine in conventional?  If so, clean engine and make sure terminal wires connected well to trucks/pickups.  If still no joy adding, the board is suspect.  Depending on which board this is determines if it can be repaired at the component level.  3V boards yes, 5V boards maybe,   G

Early 5V, if original

Thanks guys Ill give that a shot and let you know. Not sure is its 3v 5v not sure how to determine that.

Have you tried the Recover Engine option?  I'd do that before taking it apart.

Just a thought,,, Has the battery ever been changed.... A dead or weak battery may be worse than no battery at all. How long are shut down sounds after track power down ?(not shut down with remote)

It doesn't get the watch dog and starts up in conventional.  Recover engine is not a cure for that symptom.  G

Check the screws that hold the hot( to the pick up rollers) and the commons on the trucks to see if their loose. Also put a freshly charged battery in and see if that changes anything..

Battery seams ok voltmeter shows solid 20 .  Should I still try a new battery or does that seem ok?  I charged overnight.  Engine very clean. Low hours.

Battery should read above 8.4V if fully charged, plus you need to measure while loaded with a light bulb.  If white battery, it is too old and needs to be discarded for new.  G

Im sorry I had the voltmeter on the wrong setting. Its 9.4  I am not the original owner and the battery is Green. Is it worth trying a new battery even though the power looks fine ? All the connections look perfect. Engine clean. I may have to take up to the local hobby shop and let them fix it. Thanks everyone for all your suggestions.

Here is what I would do, change the battery and set it on the track and charge the new battery for about 15-20 minutes. Kill the power till it shuts down completely.  Next I would do is repower the track and do a Factory Reset via Transformer. Then recover engine on the DCS Remote. Hopefully this helped and other inputs did as well.

The question is... Why is the engine starting up in conventional? poor dcs track signal or engine problem (that could include the  battery).

 Does the engine start up in conventional every time   upon powering up dcs track?

If the engine stayed dark & silent there  might be hope .

Well again  ( forgive me Im new ) the engine is dead in the water. Unless I jiggle it around on the tracks to try to get some life out of it. Then sometimes it starts up. makes noises and does nothing else. Once in a while it goes around the track at around 10 SMPR until the hand of God pulls it off since there is no way to stop it.. I even set up a test track to mess with it since I was messing up existing engines on the track.  Fun hobby......when everything works :-)

If it is moving on conventional there is hope.  But if this makes you feel better. I just finished rewiring with LEDs an Atlas cab that the electronics board fried, Even better one of my GN GP30s 5v board also died over the weekend. Love the smell of burnt wiring in the morning.
