Voltage of LCD?

Could i run my leds and switch off the power line from the battery to the lcd as i cant get into the power cable from battery to motor which is a MXSUS 3K TURBO?
Thank you.
I don’t see why not. The current in the red wire is only limited by its size because it's connected directly to the battery wire inside the controller. You could probably run them off the blue wire if they don't take much current. That would switch them on and off with the controller when you switched on or off the LCD.
Would i need to use a fuse or with it coming from the battery to the lcd it would be ok and the on/off switch which has green wire and a black/white would i need to put that somewhere in the mix??.
I know its a big ask but im very unsure on electrics, would it be at all possible for you take time out at some stage and draw me a diagram for me to follow your instructions and send it with your reply please?.
Kind regards.
Andy.
If you connect to the red wire, a fuse isn't really necessary, but if you connect to the blue, you need one to protect the LCD in case of a short in the lighting circuit. I'm not sure what current the LCD can provide. I'd guess around 500ma of which maybe 100ma would be required by the controller, so a 200ma fuse should be safe. At 84v, that would give you 16w for your lights, though I wouldn't go higher than 5w total, which should be enough. the fuse should go between the LCD cable and the lights, not between the battery and the LCD.
I can't say anything about your green and black wires without seeing where they go.

The green wire and black wire come out of the on/off switch which bought and thought i may need
That's simple then. The green wire goes to the LCD (whichever wire you decide to take the power from). In that wire you put the fuse (if you have one), then it carries on to the switch. the black and white wire goes to the positive side of the lights. If you have more than one light, you split it to the positive side of each light. You then connect a black wire to each negative side of the lights and connect it to any ground (black wire).
Are you sure that you want to do all this? How are are you going to get your 84v down to the voltage the lights need? I gave up with all this stuff years ago. It's much easier to use battery lights. A bike with a 3kw motor running at 84v is going to need a lot more power for the lights than what that tiny LCD wire can provide. disregard what i said about power before. I was thinking of a bicycle.
Something like this, maybe:

Bloody hell thats alot of lights. Hope you dont live near a airport lol. The leds are 12-85v and i have two modules with each having 9leds per module
When fully charged its 84.2volts thats why i thought the 12-85v 9 leds per module ×2 would be ok to use
Am i missing with trouble with a capital T.
Any chance you could draw and attach a wiring diagram based on what i have said please??.
Thanks.
Andy.
