Amazing tutorial! I am measuring the ignition coils to my truck, Primary should read 0.6 - 0.9 Ohms. Multimeter set on 200, the readings I am getting are; Coil one 02.5; Coil three 01.9; Coil five 01.6; Coil seven 01.8; Coil two 02.6; Coil four 02.3; Coil six03.8; Coil eight 03.6. When I set the multimeter on 200 on the screen it shows 1. Do I extract the 1 out of the readings?

Make sure yall follow. Page is fairly new but I’m posting often!

Hmmmm are you sure they’re supposed to be 0.6-0.9? And no you don’t subtract 1. Higher the resistance the older the coil and the less voltage it will produce. High resistance is bad for voltage flow.

Im checking my ignition coils. Kia rio. 4cylinder Output is 5.99 , 5.96 , 6.06 , 6.06. Are they fine or must i change

Idk the standard for your car but if they are all equal that’s reassuring and likely fine.

If I’m doing this on a motorcycle, my coils look the exact same btw, but should I just replace all of them while I’m at it? I’ll be testing mine tomorrow.

On a motorcycle likely only 2. Also they are likely a different configuration and set up.

@@chipsisshook1741 yes. Same concept. Connections are just different is all.

Is amazing no alot of body is talking and he dont know about this point i have missFire in all cylinder without any fault code on the scanner and i have alot of think after i saw your video i teat my ignition coil is give me 2.9 & 3.0 but the problem i dont know what is the standard range u can help me to know what the stander range or my vehicle 🫡

I just tested my motorcycle one, the range is supposed to be 1.6 to 1.8 ohms and I got 2.5. Does this mean it’s bad?

No. That’s small range. If it runs it’s fine. I wouldn’t even check em unless you’re having a miss. Mild increase in resistance isn’t an indicator it’s bad

@@chipsisshook1741 check spark plug. Ignition coil. Compression. It’s one of those things long as getting gas to it. What was ohms on other coil? Similar or different.

If other coil is 1.6-1.8 then yes that 2.5 is prob bad. As resistance increases forage decreases could be causing weak spark

i checked all my 3 old four coils' output circuit for toyota sienna 2004, they showed nothing at all for output. BUT I didn't understand why my car still ran and idling smoothly. Any ideas?

Not checking resistance properly.
