Bench testing glow plugs

[madmax04]

Is there a way to bench test glow plugs,shouldnt I be able to ground the body and supply power to the post and get heat?

[dzchey21]

using an ohm meter is the only way, if it reads open circuit its no good, if you have resistance )to a point) its good. you can do this in the truck as well for diagnostic purposes

get a test light and put the clip on the positive side of the battery post now touch the end of the glow plug if it lights the plug is good if not get a new one.really easy way too check in the truck also.i have been using this method forever and it always works and it is easy

^^^ thats a good idea for someone who doesnt have a meter to use good call.

thanks man i just always use that method because it is so easy and quick,just pull your valve cover harness and find the 8 (4 on each side)of the same colored wires and check.i think they are white if i remember correct.

If you have them out, you can hook them up to a battery charger. My dad showed me how to use them to blow stuff up so that's only way I know that lol.

if they are out i would replace eveyone,they are cheap and you already have them out just do them all.you will be glad you did.
