Irregular flasher cadence

My hazard flashers blink with an irregular cadence. Looks like my if is trying to send out an SOS signal. Can the fix be as simple as needing to replace the flasher? Normally it's not for me.....haha

Probably the Flasher relay...if you installed LED lights for flashers, the difference in impedance would affect the flash rate. Any parts store has the relays

That sounds like a flasher going bad. Once had one that got water in it and got a little rust in places. That did a bunch of wierd stuff. Crawl under the dash and find it now, while it is still making noise and easy to find. When they go quiet, they disappear under the dash into a dark hole that you will never see it.

+1 for bad flasher.. Just replaced one a couple of weeks ago because of the same issues. Works perfectly now.

lol true, you would think as there isn't a lot of room under/behind the dash that things couldn't get lost into the black hole;D

And practically guaranteed that the first one you find is the "other" one. So if you're looking for the turn signal flasher, you can easily put your hands on the hazard flasher, but can't find the signal. Just the opposite if you're looking for the 4-way flasher unit. Guaranteed to find the turn signal one!

Good luck. Maybe you'll even be lucky enough this time to find them in their original factory locations.%)

Just another FYI, when I built mine I put 2 or 3 of the $0.57 ones in from the parts store, brand new, none of them acted properly, just like you say, some didn't even flash. They look like Picture #1 (aluminum Housing)

My parts guy had previously sold me a flasher for something else (what it was my mind escapes me) that is an actual relay, weighs about 2-3 oz, and you can see the coil inside of it. Cost was about $9 So I tried one of those in my 71 and haven't had a problem since. Picture #2

Some were snapped into a light weight clamp bolted to the column support. Other EB's had two strap clamps. Still others had the blue plastic ones with the little nub on top snapped directly into a hole in the support.
I've even seen supposedly unmolested EB's (way back when) where at least one of them was simply hanging there in space (relatively speaking) surrounded by bundles of wires.

I can't remember if I ever saw one where they were on both sides of the column. I think that was mostly cars and other trucks. Most had them both within sight of each other on the same side of the column, but half buried in wires so they were actually hard to see until you had time to stare at the mess for a moment with good lighting.

After all these years and potential PO fiddling, there's no telling where you might find them.

Oh, and I replaced mine years ago with one like Grant mentioned (a little longer, but looks just like it otherwise) and love it. It has a nice loud click that makes it much harder to forget to turn off your signals after your turn signal switch's cancelling cam gives up the ghost on a cold morning.;D
