[s-cars] Nutz again revisited

[Mark Pollan]

Hi Bob:

Just a shot in the dark (I tickle myself sometimes) but how about the load
reduction relay?

That light at the end of the tunnel now seems to be an onrushing train.  :-(

OK - more results:

I replaced the main headlight switch assembly which includes both the main 
head light switch, the turn signal stalk/switches and the dimmer switch as 
well as the cruise control switches.  BTW, I have such a used switch for 
sale in good working condition.  Part # 4D0 953 513 C 01C.  Retail cost, 
new, $120 plus s/h.

No joy.

Replaced the electrical portion of the ignition switch.

No joy.

Repeated the test at the fuse box checking for voltage at the fuse.  No 
change.  Power is still not getting to the light relay trigger 
connectors.  That's not terribly surprising since the lights aren't working.

Now what?  It really would be nice to be able to drive my car after dark.
