Hello, on my 1967 Convertible. When the car is NOT RUNNING, all lights work great. When the car is running.. The break lights cut out after about 5 seconds and never come on again until the car is shut off and re-started. Headlights start to flash after a few minutes. Everything is great and operates as it should with the engine off.
Do I have a bad alternator, or is the electrical going to the lights wired wrong, etc??? Any ideas? Thank You..
