Slow blinker when I brake

I'm hoping this is nothing more than a faulty flasher. I have a '79 F150. When I turn my blinker on (left or right), it flashes normally until I press the brake pedal. When I press the brake with the flasher on, the flasher becomes weak and slows down to about half the speed of what it should be flashing. Does this sound like a bad flasher to y'all?

It sounds like its either a bad flasher or a bad ground somewhere. I would start by replacing the flasher since that is cheap and easy. If that doesn't work, start checking your connections inside of the taillights.

Thanks for the input. I hope it's something as simple as the flasher. I'll try it first obviously and go from there. Thanks again.

The slow flash is usually indicative of a greater than normal load. Since it slows when the brake lights come on, my guess is that the brake light ground is bad.

I believe you're right

I tried replacing the flasher...afterall, it is the easiest and cheapest solution. I didn't fix the problem though. I believe I have a wiring problem in the tail lights. The PO installed a heavy bumper with brake/flasher lights built into it. They did a horrible job when wiring it. They simply tied wires together and didn't bother taping, soldering, etc...They left them all exposed. Willing to bet my problem lies somewhere in their wiring.

I would bet that you have a short between the turn and brake circuits, could be as simple as a broken filament in a bulb. if not it is down and dirty to clean up the messy wiring
