Bill,
Thank you for the info.
Will install a resistor to eliminate dismantling and replacing bulbs down the road.
Thank you again.
Monte

 We will be changing from factory installed battery powered lights do we need to change bulbs?
Not sure if the original bulbs will live with track power.
Thanking you in advance for your help .

Joe-

The wiring schematic - a big help.
I don't have anything to report at this time due to other commitments that are causing delays to railroad engine repairs.
Will follow with test results.

Thanks to all for your help.
Monte

Joe-

We did make sure the front truck was in the proper position. Will get her on the bench do the inspection and ohm test.
Will be a couple of days and will advise the results.
thanks again.
Regards,
Monte

Joe - Will follow-up per your suggestions. The first time we had this problem with the Annie it had very little run time and was on clean track (indor layout). Second and third time on out door elevated track that was resonably clean. I have been able to run the loco by using a Tech II power supply. With the Tech II we periodically get the, jerky/jerky, stop,reverse and forward motion but it has not knocked out the Tech II (less amps?).

NM- Will check for loose wires and check the polarity switch.

Thank you both for taking time to help.

We run a 4-6-0 Annie and during operating we have experianced reverse polarity that causes problems wth our power source ( Bridgewerks 220RM).

We notice that while operating the back up light on the tender has a very quick bright flash of light ( last only a split second in time). This happens while the locomotive is running forward and the same thing happens with the front headlight when operatin in reverse.

It appears that somehow there is current being feed to the lights when they should be cutoff from any voltage.

If the locomotive is allowed to continue to operate eventualy it will come to a sudden stop goes immediately into
reverse then to forward and stops because it knocks out the transistor board in the power source. This power source is high amp and very suscepable to even a small amount of reverse polarity.

Note: Operate several Bachmann and other loco's and only experience the problem when using the Annie.

Could this be a polarity switch problem? Any ideas would help.
