When running the motor now under no load it makes noise & you can see sparks inside. If I reverse the polarity it seems to run normal, but for me that would run the wrong way.
I opened it up & a piece of wire fell out (can't quite see what wrapping it came from) and one of the contacts also fell out & is bent.
Guess I could try to replace it, bend back in place & can hook up 1 of the 2 wires that would go to it as there is enough slack.
but still thinking this would be a lost cause.
I do now see why someone commented on wasting a bunch of zip-ties when they swapped motor rear connectors due to the springs pushing out the brushes.
Anyway, I am really looking for feedback on this type of dual motor setup. I have seen many where the 2 motors are basically bolted together with one slightly higher up then stock & the lower one kind of hanging there or they completely modify the rear swing arm by cutting & welding to make room for both motors up higher.
What I am thinking of doing is something inspired by the Punisher with one of the motors mounted high on the swing arm to keep what little ground clearance there is without dropping that down 3 inches. (need to peal off that sticker off and will be replacing the rear sprocket eventually)
I know I need to be mindful of the chain not hitting, alignment and taking up slack when the chain expands from heat.
In the above photo I have a small spacer under the angle iron so this is not sitting on the tire, I think I can move it up a bit more or add a gear between the 2 motors so each has more chain wrapping around the sprocket & also use the stock chain tensioner. ( I left the stock chain on, just removed from the mounted motor & then ran a length of chain to see how this all aligns)
I does not seem like this will hit any of the plastics when the seat assembly is put back on.
May still go with the together setup examples.

Anyway, any feedback or comments are welcome
