That's still fairly simple, though. Just use a big a$$ diode to ensure it doesn't break down and cause issues. Forward voltage 20V or more, breakdown (reverse) voltage good and high (30-50V or something).
Watts = volts x amps, so just check the fuse amperage for the circuit you use the diode on and multiply x 15V. |
Totally forgot about that relay! That's what I'll have to do
But I'll admit, got quite confused by how you work out the wattage. So, would it be 12v multiply by the amps of the sidelight fuse? :/
