2002 Boxster S No electrical Power at all

[Bill Ladd]

Sounds like you have a multimeter. Start tracing voltage from the battery and move down the circuit path until you no longer have voltage.

Do you have 12.9v to ground at the line side of the kill switch? If so, do you have 12.9v to ground at the load side of the switch once you’ve turned it to the on position?

I’ve never been around a Boxster race car, but used to race a Formula Ford. Much simpler wiring scheme on a race car. This shouldn’t be too hard to figure out.
