I am still having problems tracking down the battery drain on my 1964 & 1/2 coupe. For those of you who haven't been following along: Red has a 260 V8 and the generator was replaced with an alternator by the previous owner. Alternator and voltage regulator check out good. If allowed to sit, the battery will go dead in a few days.
I have tracked the problem down to the RH tail-light.
Putting an ammeter in line with the battery indicates that if I pull the orange wire with blue stripe, the drain ceases.
With this wire disconnected, I do not have a RH turn signal or brake light.
I have replaced the tail-light housing and the bulb but still have the problem.
I am stumped. Where do I go from here?
What should I check next?

My suspicion is the turn signal switch, behind the steering wheel. There are rivet heads on the back of the switch, and they can short out to the metal backing plate, causing a fair amount of current. If it was the rear taillight plug, it should be fine except when brake, headlights, or turnsignal is on. me check your shorts! My multimeter is just a-waiting!
