Chaps, what's the quickest and easiest way to test the glowplugs, I've got a multi-meter but am no electrical engineer if you know what I mean. I'd like to avoid unplugging connector blocks as per the stilo forum reply, I seem to remember that you can do it an easier way?

I'd say the problem will be removing them..I'm pretty handy with a spanner and was going to swap em out...but had one look and thought what a stupid place to put them!!
Looks like half the engine has to come out

People used to moan about changing the glow plugs in the old Ulysse, but I changed mine on that, but the Ulysse was a walk I the park compared to the Multipla.
It's a good job the Multipla can manage without them in our climate, because my warning light has been flashing for about two years.

If you still want to test them:

Set your multimeter to a low-range ohm reading - 1.2 ohms is a very resistance value, so if you've got the meter set to read up to 1,000+ ohms, 1.2 will just look like 0. If you've got a posh auto-ranging meter, you don't need to worry about this.

If you do get a 0 (or an infinite/very high) resistance reading, the glow plug is ready for the bin.

All four of my Multiplas have had the glow plug warning light flashing. They always started, no matter how cold it was. If it is very cold I usually turn the ignition on until the GP warning light goes out then turn it off and do it again. It means that the ones that are working are fully hot.

I also looked to change them in the past, and decided to leave them well alone. Sod of a job, by the looks of it.

If you want to test a component without unplugging it, you can try to reach the metal parts inside the connectors with your test pins.

If this can't be done, you can stick a needle (or a pin) through the wire itself and do that with both wires. The holes are so small that they close after removing the pins.

Strangely the glow plug warning has just stopped coming on after years of flashing and me ignoring it. I had the ignition switch cover off to fix the indicator relay which needed contact cleaning but it can't be related?! Fiat electronics :worship:
