My vanagon will not start.
No current to starter solenoid (small terminal) which ign. switch turns on (or ever!).
*If I jump current from main 12V post (off starter/from battery) to this small solenoid connector, relay engages, starter starts, and engine will crank.

I just replaced the ign. switch (electrical) last night with no change.  What else is there to check?

I did notice these changes in my ign. switch parts:
Original - 4 main male connectors and two smaller male connectors: "P" and "S"....
New      - 4 main male connectors but no "P" or "S"......
What does "P" stand for (park?).
What does "S" stand for (solenoid/starter?)

Pls. help me get my Vanagon back on the road w/o going to the $ mechanic.....

Thanks
