@@ScannerDanneris this a main ground from the block to chassis/battery? Or a bad ground somewhere else? I’ve had my chassis ground do weird stuff but always wondered if a bad ground ina separate circuit would do the same thing..
Rules of governing on parallel= adding another resistance on a parallel circuit, increases total current flow...it seems this is what's happening here, pump alone it will good when you add head lamps another load, ground path can't handle anymore due to current increases making the shared ground thats already loose or corroded gets hot, temperature affects current flow and this is the example.
Old Ford Truck had starting problem. Somehow the headlight switch is tied into the ignition system. Replacement of light switch fixed all the weird crap that was going on. 35 years ago so I don't remember how I figured that one out. Crazy things can happen.
Although the bad ground title of the video explains it well, to be honest that would not have been my first thought. Just like headlights dim when a starter is used with a weak battery, the fuel pump may get less juice when lights test a weak battery, too. And this might be a first clue with a failing alternator, where the alternator can't keep up with high demand. I remember limping home one cold winter night like this with a bad alternator. Those wise enough to do further testing might show another clue, like voltage drop on the ground line. The bad ground could mess up alternator charging, so I can see how the unwary might get a new alternator by mistake! The take home message is not to have tunnel vision. It makes me wonder why some are so quick to call the alternator bad, without drop testing each side.
For sure! I'm hoping with time that people understand these shorts have the links to the original video they're pulled from and when they have questions or judgements lol that they'll start watching the full video first.
Just wire in a secondary fuel pump and tie it into the headlight switch, that way when you turn on the headlights it kicks on your secondary pump and makes up for the lost power, easy peasy
Find the ground wire more than likely it’s dirty and not doing its job I clean mine with battery cleaner my car was not starting next day Evan with brand knew battery it took me a while to figure all the fuses I checked them all no dropping voltage so just for the hell of it I clean the battery cables real good tape them up cleaned all the grounds so far so good only when I put the air conditioner on does it get a little funny the ants go down but that’s normal but are you gonna 96, 4.6 with 160,000
I think that's probably a weak ground somewhere, But i actually had a Nissan brought to me around 1 year ago with the same complaint but the cause for that was a burnt out tail light, some Nissans do weird stuff when there's something wrong with the tail lights 😵💫
If his control sided systems like lights causing these misfires then most likely sounds like a load issue potentially a wire issues like an open or short ground.
Wait so the customer actually described the problem correctly? That's insane.
He did! And he smelled like alcohol when he came in and I thought he was just drunk lol

@@goinhot9133check out the full video linked in the short. It's only 11 minutes long. Thanks so much!

That is crazy. Good stuff Professor.

Funny you say that becuse I had the same problem on a 1995 Ford F250 I w as so happy the switch was the fix
My father had a 53 ford you would have to pull the headlight switch out to start the car??
Saving this to my playlist.
That’s wild I would have never guessed that could even be possible
Just don't drive at night 😂
😂😂

Turn up the radio.
I had the same thing. While signaling, while braking, and headlights.
It was the alternator.
Check out the full case study linked in the short. Thanks!
Thats wild 😂. Thats about as bad as my lawnmowers ignition being grounded through the headlights lol.
Thats crazy. Thanks for bringing the weirdness.
Amazing this one is really different, it sure must be a corroded block ground, but that's my opinion😅
Thanks for sharing SD, STAY BLESSED🙏🏻🙏🏻🙏🏻
Oh my God, the video was posted before 11 I really thank you for all the love from Yemen ❤
Had headlights and blinkers cause a pickup to do all sorts of stuff. The dash had all the lights on. Traced to corrosion in fuse box.
First thought might be something to do with the alternator or maybe bad grounds.
lol awesome thanks for sharing
I would say check the fuel pump ground with the headlight off then test with headlight on.
I did that exact thing! Check out the full length video linked in the short. Thanks!
Chassis grounds rotted off, lots of that up here.
Crazy!

Yep. Ground problems.
trying to find a path to ground
Well you could look at it this way .when ever you have to use any of those lights you probably should be Slowing down any how lol

You will have to post the scene of the crime
i think short to grond in headlight wiring
Thats crazy

What make would tie the fuel pump with lighting? Im gonna guess saab?
Grounds!
That's crazy
Right? 😀
Bad ground.
Expect a fire, with bad body grounds.
Incorrect
Fuel pump getting power from lighting system😢😢😢😢
Ground loop
Bad ground
Strobing alternator with bad ground. Common Ford truck issue. Check all Body ground. You're welcome
Nope lol
@@ScannerDanner what's the year make and model?
@@pathlawncare744 full video is linked in this short
Hahahahq
Shitty ground
Bad alternator or incorrect wiring
