all the controller must be in the motor. nothing in here:
even pulled off kickstand to make sure nothing under there:
so i removed the battery connector from inside the compartment and hooked it up to 41V (10s2p puffy lipo).
but question #1: what is the yellow wire attached to (that's on one of the main connector pins? it's the only wire not hooked up the the black or red mains.
after startup i got this (MSG: NO_COM)
but lookee here, a broke wire!
so i carved out the plastic to get at some theads, twisted them up and reconnected them:
the raw alligator clips attached to the lipos were asking for trouble so i soldered in some 4mm bullets for testing purposes:
so i attached the lipos and fired it up. got two startup messages - questions 2 & 3: what do these mean?
i toggled thru the menus and saw two regen modes, one blank mode and 4 PAS modes. on braking the regen seemed to cause drag.
but the throttle or pedaling in a PAS mode did nothing. tho the bike was so light i almost thought it was helping!
so is it a clue that there's some regen happening?
need to look up those error messages...
i could redo all the wiring in case an internal connector is bad. but maybe i should try the other stromer first.
i'm guessing it's not working cause the yellow wire is not connected, and that's probably attached to the BMS somehow...
what the heck, let's check the wires coming out of the motor, if someone yanked on them as it looks like they had there could be damage:
don't see any damage... so let's take a peek inside the motor. looks like it screws off. so first we remove the freewheel:
now lets angle a screwdriver against one of those slots and give it a couple taps... hmm, nothing doing. maybe that sidecover doesn't screw off...
question 4: you cannot possibly tell me that motor only comes apart when the spokes are off? i can't believe that! i don't trust my eyes, and a seam could have been painted over...
so close but yet so far!
if i can get a new/used stromer batt and have some confidence the bike will run, that will be the best option for my wife. she would burn down our house in two days if she were to charge lipos. i suppose another chemistry would be fine, but if buying a batt, why not a stromer batt, esp as there is likely an electrical requirement.
i could install another hub motor/controller/batt, but this is not to be hotted up. the slower the better for her. lol.
maybe it's time to take apart and play with the other stromer and see how far i can get. lol
