LS170 glow plugs not working

[Skidster200d]

Hello, I have a LS170 that is not starting cold. I replaced the glow plug relay and still the glow plugs are not heating up. Power is going to the relay but not coming from it when I turn the switch to turn the glow plugs on. The indicator light goes off after a few seconds and I hear the relay click but no power is being sent to the plugs. Any ideas? Thanks in advanced!

Have you checked with a DMM that there is no voltage? It could be that all the plugs are burnt out from a faulty relay.
Check for +12v at each glow plug when the relay is active. If it's there, check for open glow plugs.

when checking to see if the glow plugs are good they should not read much more that 3 or 4 ohms , this can be done in machine ,take off power lead off glow plug connect there one lead from meter the other lead go to ground. repeat at each glow plug make sure they all work.
