all;
the car is a '69 that has had the alternator upgraded to a 75 amp internally regulated unit. (Paris - Rhone FWIW) i get 12V to the bulb. the bulb is good. the bulb does not glow with the key on and the engine not running. grounding the +61 terminal from the alternator to the engine case does not cause the bulb to glow.
can someone give me some tips on tracing this part of the circuit ?

i'm new to 911's, but after 25 years of 4-cylinder bliss i could be a
convert ;-)
thanks in advance!
cheers
jerry
