How does one check glow plugs
How does one check glow plugs, if they seem to be working (to ensure they keep working)? Do they wear out gradually, or burn out suddenly like a fuse/lightbulb? How can one tell if they are still good or need to be replaced? Is there a normal replacement cycle, or can they last many years?
For someone not mechanically inclined, is there a quick check, or does one need to dismantle things to get at them?
I'm hoping it's like checking spark plugs on a car--unscrew, look, clean, re-install....
Thanks for any replies.
