@sherpa.offroad: How to test a spark plug #jeeplife #offroad #jeepwrangler #4x4 #cars

SmackinDummies :

as a mechanic I'm not sure that that means it's good All that means is there's continuity between the electrode

Jonny H :

remove spark plug, put spark plug in spark plug wire, ground against block, turn engine over, bright blue spark good, red spark no good.🤪

mozzo74 :

this is the biggest load of shit iv seen on the Internet for weeks, it does not show a good or bad plug. just shows there is continuity, not good spark

Ryan Davis :

Just cause it fires dont mean its good

Ruaan :

there is a big difference in good resistance and bad resistance just saying

It’s called a test light

None Ya Biusnitch :

It must be true… I saw it on TikTok

Michael Rigsby912 :

But wouldn’t a voltage tester do the same thing?

robbob :

I can’t remember the last time I actually saw a bad spark plug. 99.99999% of the time at

Donnie :

Would work

user1457018336581 :

that doesn’t mean stuff.

Ry_guy57 :

Or or…… hold the spark plug wire with one hand and hold top of spark plug with other and then have your buddy turn the motor over.

Steve Rand 🇦🇺 :

dannykoring2 :

you can use a multimeter to

Platitude_Shelf :

ceramic is super fun also

LXPens :

Or a free multimeter at Harbor Freight can do the same thing.

Mark :

You can do that with an ohm meter.

Chepe :

Hamms3 :

that's what you call a test light that have been around for years

Cash_23 :

colonbia :

the trick is more old than when your great grandma used to write a little scooter in front of the front yard lol
