Lip filler check: Is it safe?

Hi.
Is it possible to check the glow plugs while they are still installed, for example, using an ohmmeter? And what should the resistance value be for a good glow plug?


Thank you, and best regards, Mark.

Hey, we've already discussed that; the search function is your friend.

Best regards, Rainer.

Hi.
Thank you, but I can't find anything using the search function. Do you still have the link? If so, could you please send it to me?



Thank you, and best regards, Mark.
