Hi d8veh Thanks, will check tonight. If they are blown do you happen to know what the halls sensors are in a bpm2 350w ? I'm near a maplin today and tomorrow so have a chance to pick some up Cheers

Looked inside and all looks fine Halls are well seated Any ideas ? :(

I've tried all 36 combo and identified the the smooth, forward ones But it is still noisy and rough, more so than my ku63 square wave Hall connection inside the controller perhaps ?

Hang on a minute, once you can do that you can use the battery as an app co trolled powerpack for anything powered by usb It almost becomes an IoT base station of sorts Which would be cool

Hah ! But I know what he means though I imagine a Putty like substances (like Sugru) that you can squish into any old socket with two wires sticking in it which senses + and - , separates and insulates and hardens to gives you an instant perfect fitted connector I know, keep on dreaming

I'm just about to pick up a 5.99 halfords computer to cut the sensor off My Speed sensor at the controller has a ground wire as well. Presumably this can just be ignored without issue ?

Ahhh penny drops ! Thanks Kirstin

Ah that makes sense My controller is huge, bigger than spec on website . It also has 30a stamped on case

Thanks but I'm really confused now Coming from the motor I have 3 thick power phase wires. I then have a further 5 thin wires for halls (Green, black, blue, yellow and red )

Nope, Brain still can't work this out ! I've made a spreadsheet to check back against but only 25 options as 5 hall (5 x 5=25) What am I missing here please?

Can I just check if that's a typo d8veh ? 13a not 23a ? Mine is set to 25a and you dial down in settings by division amounts. The biggest is divide max amp by 2. Which is 12.5a or 13 near as Or am I misunderstanding

38mm I could on front but not rear I see what you are getting at but I think a suss fork will protect myself and motor from shock a little better than balloon tyres

Looks like I'll have to do that , all the LCD settings are correct having worked through the manual of g , p and c settings Giving up fir tonight, too knackered to try and work out the combos ! Cheers for help

All hooked up but runs very rough, noisy and kind of wavery Halls colours misaligned ?

Ah mine is wireless, need to buy one Although if I understand right, it will work using the halls if I can fund it setting parameters

Ah no, not got a Speed sensor, didn't know about that as it wasn't onn the wiring diagram which I checked before ordering Ah well, I guess it will still work? Just not as a Speedo? Thanks for speed of reply, there are bits all over the kitchen and wife not looking best pleased !

Thanks ! That was quick , and yes does have large plugs, I only use one and, like halls, solder directly

I also have an extra wire not on the diagram It's a blue and black with a loop Like this

Hi all Never had this before.... Trying to hook up my new s12s controller to my bpm2 but......it has 5 hall sensor cables and the controller had 6 (an extra white one) The wiring diagram only shows 5 as well What's going on here ? Thanks !

Thanks both much appreciated
