Starter solenoid

[Nutter.]

Hi does a starter solinoid need to be earthed.  Thanks in advance

Depends on the connections on the soli........ One connection and no - it'll be earthed through the body, two and one side will need connecting to earth / frame. But if the starter switch, switches to earth then one side will be switched 12v, the other up to switch.

It's a 750m  using wn battery box + gsxr1000 shock all electrics work except starter soloinoid has 2 cables 1 from starter 1 to + on battery and 2 terminals but nothing at button.

Should be 2 small wires, black white= -12V, green/yellow from memory= +12V from starter button
