I just bought a car and it keeps blowing the same fuse when ever I put the headlights on.
There's a 40 amp 5 pin relay
Pin 86 - Earth
Pin 87 - Thermo Fan 12v
Pin 85 - Kill Switch OFF position
Pin 87a - 2nd Rear Thermo Fan
Pin 30 - has 2 connectors (split) 1st wire goes to one side of the fuse
2nd wire goes to the Kill Switch ON position
Now 2nd part
It has a solenoid R2D2 look-alike that distributes the power (power distributor)
Left Big Terminal - 12v to alternator, also a wire that connect to the other side of the fuse from the relay above (pin 30)
Right Big Terminal - Starter Motor
Left Front Small Terminal - Ignition Coil
12v from the Battery goes straight to the Alternator and a big wire from the alternator to the Left Big Terminal of the Solenoid
Should the thermo fan have its own relay, then not sure if the solenoid needs a relay for the kill switch.
Thanks in advance
