hi everyone. i have used a multi meter to read the ohms on my glow plugs.

3 glow plugs are 1.3 ohms

1 glow plug is at 0 ohms

Q1. what does this mean? is it enough to give the glow plug light on the dash which it lit up?

Q2. is 1.3 ohms normal for the other 3 plugs?

thanks in advance. God bless.
