I've done two 5-pole motor conversions w/o any issues but this one's a head scratcher. I bought p/n 211905 to replace the 3-pole motor in my mini croc and the motor is spinning backwards. So the directional LED's run in the correct direction but the loco runs in the total opposite direction... looks like I wasted $30? Is the only solution to cut off the wire whiskers from the circuit board and solder them to the opposite side capacitor wires?
The back of these motors can be pulled off and then you can put it back on flipped 180 degrees to reverse the motors polarity. The motor was likely assembled wrong. It looks like for this version of the motor, you would have to remove the rear worm to be able to remove back of the motor. Matt
Thanks, I bought these on zscale monster, will see if they offer an exchange. I don't want to muckup the worm. I don't think the trucks are on wrong as I did a back to back test with the stock and new motor.
You asked for a solution well its been given to you. The power pickup on Marklin Trucks is Directional, By putting the front truck on the back and back truck on the front you have reversed the power feed to the motor which will reverse the direction of travel.
David: What grymg is reporting is an issue I've seen first-hand. I'm stuck with dead stock at the moment as I have the same problem reported by 1 customer and verified by me. They are all backwards. I need to get back with Gale at Marklin as he has not replied to me on this in 6 months (edit: oops, it's been over a year). The motors are wired backwards.
That's a new one on me Frank. Sorry grymg. I stand corrected. But in my defence and as Frank can verify 99% of the time a marklin Loco running backwards is the result of the trucks being reinstalled on the wrong ends. Anyway I wish you good luck getting it straightened out. Frank is this backward wiring problem only on the 211905 motors or do any of the other 5 pole replacement motors have this issue?
You're right, of course. But it will also reverse polarity to the headlight control, and they will still be out of synch.
Thanks guys, I did end up swapping the trucks but the lights are now backwards. I'll live with it. I don't understand Curn's post, how to flip the can 180deg. to do the fix on the motor. For reference, I have swapped to 5-polers 211901 and armature 209454 already without any polarity issues.
The trucks may appear identical, but they aren't. They can't be. They could be if they were both pointed the same way. Then they could both feed electricity from the left rail to one motor brush and they could both feed electricity from the right rail to the other locomotive brush. But the worm gear would be a problem. Also, only one of the couplers would be where it needs to be. The other would be wedged under the middle of the locomotive's underbelly. They have to be mirror images of each other for the worm gear and coupler to be in the right place. So, they have to have opposite wiring. Swap them and you swap the polarity of the whole locomotive.
I'd agree on the directional trucks being backwards, but this is definitely not the case. The new version motors spin opposite directions compared to the original ... with direct applications of voltage to the motor. Working on a solution with Marklin Germany service team. ONLY on the 211905. I wouldn't be selling all the other motors if they were also in this state.
I have a feeling that you would need a pretty specialized tool to remove the worm without damaging the motor. Thinking about it more, your first thought might be the right path forward. The most practical solution might just be to hard wire the motor with the wires reversed. Or replace the whiskers with longer ones that Are bent in a way to touch the other side.
grymg in the picture you posted it looks like it has the orignal marklin 5953 bulbs installed. Did you install aftermarket Led's? If So Who's directional LED's are you using? No matter reversing the direction the light comes on is easy enough Their is a disk diode under the contact piece with 3 dimples in it at each end of the circuit board These diodes control the direction the lights come on. Simply Flipping this disk diode over on each end will reverse the direction the light will come on. 7 minutes in on this video shows you how to get at the diodes If your using the original Marklin Light bulbs (the ones in your picture above) simply flip the diode over and reinstall them instead of using the washer like it shows on the video.
Nice, thank you!! I'm definitely changing from stock config but its so much easier than modding the motor. I'll also have a look at those aftermarket LED's for my locos too. I've been meaning to shell out and get a modern Marklin with the latest tech built in (coreless or brushless motor?, LED's). I've been happy with my AZL Geep being my #1 though.
Thanks for posting the video about those lights tjdreams. This is off topic but I have purchased replacement LED's from HTM (High Tech Modelbahnen) both from Z Track Center and directly from HTM. They are a wonderful upgrade for the old style lights in Marklin locos. HTM lights have capacitors so they store energy and operate flicker free, plus they come in a warm white or old timey yellowish tint, and they also sell that tint for painting existing LED's, but they are expensive compared to these CKLED'S.
