Do you know what this is?
Hello, I'm a newbie here so sorry if I ask something stupid!
I have a Swish SW02 electric moped (details are here: http://www.swishbikes.com/specifications.htm )
There is a strange device connected to the batteries and motor and I am unsure what it is. I have included a picture of it below.
Do you know what it is and should it be there? Or is it a mod that someone has done at some stage to make the bike faster? The problem I have is that the red wire that is coming out of this thing has snapped off (Hence the gluegun) but I don't know what it is so I can't get a replacement. Do you recognise it at all? There are no markings what so ever!
first a question ! Did this bike have reverse ?? that looks like a group of relays to switch polarity to the motor ! is the motor brushed or brush-less ?? what is all that black on the blue boxes ? do the individual blue boxes have any writing on them ?? back LaTeR
Equally interesting is there is only a positive lead coming from it, which doesnt make electrical sense unless mokunting hardware completes the circuit. Have you tried contacting the folks as Swishbikes to see what they knew, if anything? When you reattached the wire, did you solder it in place first? From the connector, exactly where does the rest of the wire go on the other side?... to battery pack, up under the seat?,,, to the handlebars?....
It is a contactor, a power relay to control battery power to the driver electronics.
