Stop lights still not working 40 coupe

[Terry,OH]

Repeat your power test at the stop light switch with both tail light bulbs removed. If there is power to one of the wires on the switch it would appear there is a short circuit at one of the tail lights between the black and green wires. drolston is correct the green wire to the circuit breaker may be broken or disconnected (open circuit) under the firewall cover for the wiring. If you remove the firewall cover do it with the battery disconnected.
