what 2 do with second red wire on controller power input

[andrewil]

i have 2 red wires on my controller a thick one and a thin one

i almost know for sure the thick one goes directly to the battery positive

the thin one has something to do with switching the controller on and off

i just dont know how 2 connect it

- do i also connect it 2 the battery positive ??
- can i put 48 V on it ( its a 48 v controller )

Yes.

I usually crimp/solder it onto the larger red wire so that when i connect to the battery, the controller comes on at the same time..

you can install a switch on this wire for an on/off switch, but i highly recommend making a habbit of disconecting the battery when ever you step off the bike...

I always put a keyswitch in line with that wire leading to battery positive. Mount the keyswitch where it is easily reachable while riding, and that gives you all the emergency cutoff you need. I consider a switch here along with an appropriate size fuse close to the battery to be mandatory safety items, yet one or both are missing from many, if not most, builds.

I leave my battery connected to the controller at all times. If I disconected it all the time I would have blown controllers and melted conectors. I think leaving the controller conected to the battery is proper then turn the on off switch off when you are not around!

Thnx all for your feedback

i'll think i will go for a switch between the battery and both the controller wires

No. You can't use a standard switch on the main battery line. It will quickly fuse shut. To high of voltage, and to much power. Only on the ignition wire can you use a standard switch. It rocks. My controller has been hooked up to the battery 6 months now, and I have a keyswitch to control the ignition wire.

so ur connecting the thick red wire directely to the battery and the thin red wire with a keyswitch between the controller and the battery

 

[biohazardman]

Battery to fuse to heavy duty battery switch, or battery connectors or contact relay, to controller power wires, thin wire from battery to smallish switch to thin controller wire. Unlike some others I have not connected my thin red wire to my main positive wire as I have switched them separately both ways werq fine. My Infineon controller requires that that I turn on the battery power B4 the controller power or I get no power up.

YES finally got the kit working

thanks for the help everyone
