Slow blinker
Ever since I picked up this jeep two months ago the blinkers have been slow, especially with the running lights and AC on. When trailer lights are hooked up too. Any ideas on what could be causing this?

Other things aside, the speed of the blinker is a "poor man's volt meter". I'd start with metering voltage right at the battery. Around 14 is nice, running. Last I checked I idle at 14.25 with everything on.

Voltage is controlled by the PCM. It doesn't matter if you have a 340 volt alternator, it's only going to let a certain amount of amps through.
He should change out the flasher for a quality heavy-duty version. It might help. Or it might be that is just the way his Jeep is.

How can that be? There's only one belt. You are going to hear it squall if it slips. The flashers will definitely slow down when you put a bigger load on the system.

OP: Ever refreshed the connector in fromt of the air cleaner that has all the wires for your front lamps?

I'm sure someone will correct me on this, but I think 14.2 amps are about it.

I understood. Alternators just "maintain" a charge anyway. The battery stores it. It gets to the vehicle's accessories by nice and clean connections.

I can't believe nobody has suggested a lighter weight blinker fluid yet. I am disappoint.
+1 to all of the above. The old mechanical flashers react very strongly to resistance in the circuit path, hence why you lose a bulb or install LEDs and it blinks super-quick. I'd be suspicious of marginal grounds and/or a corroded connector that's presenting high resistance. Check the connectors mentioned, as well as grounding points by all of the light fixtures.

Ok, I just went out and tested a bunch of stuff. Battery voltage: 12.77v Alternator output: 14.1v. I turned everything on for the voltage tests. The dash volt meter reads 10-11v. I took a video of my blinkers working. The side markers blink... My 89 didn't do that, it was just the two under the headlights that blinked.when the lights are off no problem. Lights on, the side marker and turn signal alternate. What is this?
