Originally wiring looked a mess and was. when first tested it was a dead short as I removed all wiring and completely rewire. Thanks to all your help. One thing I did notice it took a lot of power from the transformer to get moving and it did run good. Did the old trains need more voltage? This checks out to be a 1931. All my small pre war engines like 262 252 etc run a little faster. concerned as I do not have body on or tender. That will be a much longer process. Many thanks again for help and info. Roy O
I have found that many early prewar motors need a higher voltage. You need a transformer that puts out at least 22v, but 24 is better. My 10E needs the 24 volt transformer. I use a Type A, which has 24v max. Unfortunately the knob is turned counter-clockwise to increase speed. That's counter-intuitive and I sometimes instinctively turn the knob the wrong way when there is a problem. Postwar transformers that go to 24 volts are the Q and R, but not RW. V and Z will give you 25v.
No, this should not be the case. Yes, a 10e is a Standard Gauge engine and will need more voltage than an O gauge 260e. However, my 390e standard gauge engine runs fast at 16 volts and just fine with a ZW. If your motor requires high voltage, it is probably dirty. I have soaked many pre-war engines with CRC cleaner. You should see the gunk that comes out. The bearings and gears can get dirty, too. Sometimes you need to use a tooth brush or swab to get gunk out. Then the engine needs to be re-lubricated. A 260e at 15 to 16 volts should be flying around the track.
Using more voltage than the engine was made for can fry your field coil and possibly even your armature. One guide, the motor should not be getting hot. It should only be a little warm at best.
