Why would you want to test the glow plugs. They either work or don't work and even if you test them today and they are OK, they might fail tomorrow. The older glow plugs are in series and if one goes open circuit, you can jump across it to get started. Remember the glow plugs are turned off after engine is running and have no effect on the running of the engine.
