Check the starting relay
1. Operation check
a. Remove the seat and rear storage box first, find the
starting relay connector on the right inner side of the frame,
and untie the tie.
b. Unlock the vehicle, turn the engine shutoff switch to "
", retract the side bracket, pinch the brake handle and
press the start button. You should hear the sound of the start
relay picking up, otherwise you should check the start circuit.
2. Check the relay coil
2.1 Input line
Adjust the multimeter to the DC voltage 20V file (if it is an
automatic range multimeter, adjust it to the DC voltage file).
Insert the red test lead into the rubber sleeve of the
yellow/red wire and stick it tightly to the terminal.
Unlock the vehicle, turn the engine off switch to " ", and
the black test lead can select any bolt connected to the frame
nearby. When the brake handle is pressed and the start
button is pressed, the voltage measured between the
yellow/red wire and the ground wire should be the battery
voltage.
2.2 Ground wire
The vehicle is powered off and locked. Set the multimeter
to the buzzer position, connect one test lead to the
green/red wire, and one to any bolt connected to the frame.
It should be conductive when the start button is pressed.
3. Check the starting relay
Use a thicker wire to directly connect the 12V battery to
the relay. Use the buzzer file of the multimeter to measure
the green/red and yellow-red wires, which should be
conductive, and should be disconnected after disconnecting
the battery.
4. Disassembly and assembly of the starting relay
Open the black protective cap of the starting relay and use
a 10# sleeve to remove the self-contained M6 nut, take out
the wire and screw it back to the nut to prevent loss; use the
same method to remove the other end. Unplug the
yellow/red and green/red wires.
When re installing, the yellow/red and green/red wires of
the relay correspond to the color of the main cable, and the
nuts are not distinguished. Be sure to close the protective cap
after tightening the nut.
