Why are you illiterate.
This test will determine what glow plugs are working. ( It will not determine a partially burnt plug ). Disconnect the glow plug wires at the plugs .( You must unplug all of them for this test to work ) Connect a test light to the positive terminal of the battery. Touch the electrical connector at the end of the glow plug with the test light. If the light goes on the glow plug is working. Make sure you touch only the electrical connector on the plug. If you touch any other part (metal) of the plug the test light will light giving you a false reading.
I had this problem and it was broken solder on the timing circuit board for the glow plugs
you need to check your glow plug relay it is most likely going out you can jumper it to see if the glow plug light will come back on to start engine
The glow-plugs are located under the valve covers. There is a single wire that comes out of each injector harness that powers each glow-plug. Disconnect the single wire from the glow plug. Connect the gator clip of a test light to a positive and probe the glow plug terminal with the test light. If test light does not come on the glow plug is bad.
as far as i know C3's don't have a glow plug light or only use it when it is very cold i.e below freezing
You can actually check the glow plugs with a common test light unplug the wire feeding power to the glow plug and connect the alligater clip the hot post of your battery and touch the tip of the glow plug with tester if the light comes on the plug is good also if you have 3 of 4 burned out the glow plug system will not function properly
the bottom glow plug will glow but is weak. the plug needs to glow red hot all the way across and up and down the ignigter.replace the plug
Yes. It is in the warning lights below the speedometer on the cluster. If the glow system isn't working the light will not come on.
You can test each glow plug while still installed in the engine. Just get a test light and connect it to the positive terminal of the battery and touch the point of the test light to each glow plug terminal. If the light lights up the glow plug is good if not it is bad. You can replace the one or more that are bad or replace them all since they may not be too far behind.
when the glow plug light is flashing during driving it is not the plugs that need replaced it normally means you have a bulb blown most commonly one of your sidelights and once replaced your glow plug light will stop flashing
Wait until the light turns off then start the car. Diesel engine?
the glow plug controller is grounded through the coolant temp sensor . @ 16,000 ohms resistance... normal...seems to have to have it to work. new controllers by international seem to be real resonsive. smaller electronics.
