I’ve a 1973 Pantera. New to me. I’ve got a fast turn signal (both directions) but only when using turn signals, not using hazard when it blinks normally.
All bulbs (1157 front and single element bulbs in back) are working (including the jewel Indicator in the tach) and I know the same flasher works the hazard and the stalk controlled indicators. The flasher itself is a stock three-prong in the driver’s footwell.
what can it be? I even put a 5ohm resister across the tach jewel to increase load when blinking with no effect. What am I doing wrong?
usually a fried bulb causes fast blink, all working.
