Low idle blinkers flash extremely slow

[Grandma_quis]

Hey all. Recently my grand marq starting doing little things like the Windows rolling up slower than usual and blinkers flashing slow (once every 3 seconds) and additionally low voltage sounding starts. I replaced my battery (after it tested 58% current capacity held). The new battery fixed the weird starts (for a day or two) and now I'm back where i started. Everything above is happening in addition to an extremely low idle and none of my idiot lights come on anymore when i turn it to acc (only 2 or 3 max would ever come on anyway but now its none) so someone plz tell me its just a dirty engine ground or something simple. Performance (becides idle) not affected. Garages appear dimmer

Check your alternator plugs to see if they look melted at all. Next would be having the alternator itself tested at a local auto parts store. Most will do it free of charge.

Sweet i can take a look at it tomorrow. Plus taking the alternator off is pretty easy

Your alternator sucks. Its "normal". If there aren't any obvious faults with it, the usual fix is a 3g alternator swap.

[Grandma_quis]

Well i mean it was way more normal than this about a week ago. Nothing that i listed was happening a week ago...surely this cant be normal with the alternator if it didnt always have these isssues?

Could just be the flasher getting old. I've grabbed several 323 and 325 flashers from Boxes and early Aeros back when I was using a stand alone flasher for my turn signals when I did LEDs before a load resistor was put in and I wired the flasher in the LCM back up.

Some of those flashers clacked along fine, and some of those things dragggggged. I don't know why I started grabbing as many as I did, but I did. I'll occasionally hand them off to anyone who needs a spare or a replacement.

You may have a parasictic draw or like the fellas a bad Alternator or you may have a faulty ground.

This. LoL.
After my swap none of my stuff is weird no matter how many things are turned on.

I had slow blinkers for about a week before my alternator(3g) melted the plug, replaced with a reman and it's been good since.

You might be able to find the same flashers in other early Ford/Lincoln/Mercury cars. I'm going to start looking around for them next time I'm at the yard.

Call me crazy, but the main reason I wanted an original flasher for my car was only because I wanted it to sound like I remember. I just can't get used to modern cars with their electronically-generated flasher sounds.

Don't discount the Tridon HD12. (The "electronic" one, transparent case with a capacitor in it). Most of them will drive a single lamp without issue.

Hook up a voltmeter and observe your voltage, it is probably dipping down to bat voltage when you are experiencing the weirdness as the car starts drawing on the battery under these conditions. Just make sure at night, you turn off everything and let the car run a few extra seconds to give the battery a bit of a charge.

This is why I still have the original flasher & several spares in the garage. I like that old sound. I've got solid state ones that while they work and are more consistent, they just don't sound like I remember.

Today before work it was too low to start. Battery was dead. But I'm gonna jump it and bring it to where i work (dealership) to do a load test on the system when i go to lunch. Thanks yall

[Grandma_quis]

Alternator tested bad so we found our culprit. Thanks yall
