glow plugs

I've just bought a multipla-very happy with it-but after i start it, the glow plugs indicator flashes for a minute or so then goes off. Any idea what's wrong?

is yours a jtd??. if so the glowplug light should come then go off. you can then start the engine???

Yes it is JTD and they go off very quickly after i turn on the ignition but once started the light continues to flash for about 1 minute then goes off-do i need new plugs?

This normally indicates a current problem, either too high or too low. (the light can flash after start up at VERY low temperatures, this is normal). The normal cause though of this problem is a glow plug going open circuit. If you disconnect the larger connector block from the glow plug control unit, you will have four wires in this connector which connect to the glow plugs in parrallel. Using a multimeter and a cold engine check the resistence down each wire to earth. The readings should all be equal and ideally from memory around 2 ohms. (Heat effects resistence so best to do it on a cold engine). If you have a resistence alot higher then this will need replacing, trace the wiring (the are all different colours) from the connector to the glowplug to locate which one needs replacing.

I have the same flashing glow-plug light problem in my Multipla JTD. Tried the resistance test (thanks NumanR) which seems to show that the plugs are ok.

There is a reference in the owner handbook (Pages 115 & 119 fig 35) to a "Pre-heating glow plugs control unit" 60 amp fuse no 3, the holder for which is illustrated as being next to the ABS and electric fan fuse holders located just behind the battery on the bulkhead.

Strangely, although I have found the other two, there is no fuse holder for fuse 3 on my car! (I would be grateful to learn of its whereabouts should anyone out there know please.)

No apparent ill-effects from ignoring the flashing light so far though!

What year is it?
