Hello Simon,

they can be tested in or out of the engine but you will need a good multimeter, the wire link to each glow plug needs disconnecting whilst testing and disconnect the Battery negative as a safety precaution.

Click on the diagram to enlarge it.

An easy test if you're good at home mechanics is to disconnect the supply wire, take a long screwdriver or similar and touch it against the connector on the glow plug, and take a jump lead from the poz Battery terminal and skiff it off your screwdriver. If you get a big juicy spark your plug is good,if you get a small spark or nothing then it's kaput.

Be safe tho, if you're not confident then check it the proper way.
