O2 light question
 

-new to me 1980 Targa

-should the O2 light on the dash come on when I turn the key/start and then go back out once it is running?

-mine never comes on at all

-wondering if the bulb is dead and how do I access it, pull a gauge out?

Disconnect O2S at the cat and see if bulb comes on.

Yes, pull gauge to access bulb. Disconnect the battery as not to short on the chassis,

great thanks Draco, will try that
