Hi guys
I just picked up for free a generic Rayleigh Velo trail e-bike...low powers from geared hub 36 volt PAS only bike
It has a little 3 button handle bar control unit
As in pics below
Power
Assist level
lights on/off
Now even the manual says that the lighting part is not connected on this bike..but it does 'work. Pressing it does light up a red led in the control box.
I have been told there is an SMD MOSFET on the board and it should be outputting battery voltage on to one of un used headers on the PCB...yet to test it, Picture of the unit with the top off does not show it..but there isa row of holes on the PCB, unmarked, for wire attachment
But this wires..not going to take much current to run decent lights.
So assuming go can find the switched output on the PCB in the control unit, I'd hope to run a wire to it to run an external relay/MOSFET/transistor "switch"
Assuming I have switched (36-42) battery voltage out of this control unit run from the light 'button' ..how would i drive a MOSFET from it ?
