Eletrical gremlins ? 95 2.5L

So I recently had a few odd things happen. These all seemed to happen just when it started to get cold/ Freezing


1. My Aftermarket radio died and will not play music so I bought another head unit an it too died in the same fashion.

2. My blinker is intermittent ( well its more like those old school holiday lights that blink randomly when they heat up) so it will blink fast then normal then stay on then slow , fast, an so on.

3. The engine seems bogged down when accelerating at low speeds. almost like its got no spark.

4. New battery but also slow to start (I have always thought this to be my starter which I'm just lazy to replace)


Thoughts? I was going to poke around and look for any damage from rodents or crossed wires. Otherwise drives fine.


Thanks in advance

have you cleaned and verified all your grounding points? block? fire wall? head? etc etc etc.

How are your battery cables looking? They original?

Have you done any troubleshooting? Got a voltmeter?

Stop whining about the 'ride' - If your YJ ain't wrangling your soul free, then might I suggest you buy a stationwagon... at least you can fit all your bull**** in the back.

not sure were all the ground points are

original cables but look good with little to no corrosion at the battery
Just looking around for obvious items. I do have a voltmeter.

I think checking for good grounds, is a good starting point and free. Plus if you are in rust-prone state, all grounds probably could use some rust removal, and light coat of dieletric grease after 24 years of no love.

My next thought would be to check if the alternator is producing the correct voltage. I'm thinking the aftermarket radios dying is from a voltage spike. I lost a video card to that after a power outage at the lab i was slaving away at in the university i was indentured to.

Thanks I'll check grounds again. The alternator is also original but still putting out ~ 14 volts according to the gauge.

verify that number. Our gauges are often crap.

If battery cables are original i would just freshen them up on the cheap and upgrade the grounds to 1-0 gauge wiring. Firewall ground, alternator and block.

If ya want to get really fancy, firewall to frame.

I would also replace the grounding strap from block to firewall to hood. Just because.

With replacing the positive leads, replace all of them. Battery to starter, alternator to battery, etc etc.

Have you verified voltage at idle, start up, or under load ...

Thank you for the theories. I did some work on the yj.



I doubled checked my alternator and volt gauge and was producing 14.3 volts

I also replaced the blinker relay which fixed the blinker issue. I then checked my radio an I am getting a new error. its certainly fried but not on and causing a current draw when the ignition is off. I don't want to see this was my issue but maybe has something to do with it? Next up is a new starter and I will double check the leads.
