Hi,

I have a few questions regarding glow plugs. First, what are te possible indicators of a bad glow plug/plugs besides the car not starting? Mine starts fine, but sometimes the preglow light doesnt go on until the other left side lights such as battery, etc go out. Someone said this may be a sign of a bad glow plug, ut Im not sure if maybe its just a bad connection. Id liek to know the possible lighting behaviors of the preglow light, if it blinking, turning on in different ways/not at all may indicate a problem or something.

As for actually testing the plugs, Id liek to know the procedure. What should I connect to what in order to test the plugs. Will Ineed to remove wires, etc? I have no idea how to do it, so Id appreciate helping a newbie out. Also, I dont have an ohmeter. Currently the only thing similar that I own is a battery tester... Any reccomendations on a good cheap ohmeter that would be good for this type of thing would be appreciated. I would guesss radio shack carries this type of thing?

Any help would be most appreciated. Thanks very much,

JMH
