New glow plugs required

[jenevers]

My generator’s been reluctant to start recently. Held it on “Glow” for 20 seconds and felt top of the glow plugs.....stone cold. Should they be warm?

[Tony Brooks]

Possibly not because its screwed into a very large lump of cold metal. I would measure the current flow but you can't do that with an ordinary multi-meter because the current flow is far too high.

[GUMPY]

Measure the resistance of each plug.

It should be between 0.1 aand 6ohms and they should all be much the same.

If one or two are much higher then they are duff.

Best to compate results against a known good plug.

The only under resistance I have ever encountered in a glow plug is a dead short. The only over resistance I have ever encountered is open circuit. If a test lamp in series lights up and the fuse isn't blown then I'd say that's it.

Great stuff. I'll give that a go next time I'm aboard. Thanks to everyone?

[mrsmelly]

Are they not a cheap serviceable part anyway?

Checked the glow plugs and they need replacing ?. Anyone know where there's a Mitsubishi outlet that deals in generators, or would a car sales, parts department be able to supply?( Genny engine is a Mitsubishi L2E)

About £42 each for genuine Mitsubishi plugs !

Not expensive then, if you consider that batteries are disposable and even at £500 they need replacing every couple of years.

£164 for (probably) 10 years plus = £16 per year.

 

My raw-water pump is over £450 - take it you've not had many mechanical problems this century ?

No problems I always buy Japanese lol. Like u say though that's worth paying to know they are all OK. Boating ain't cheap.

The kubota and Honda are your safest bets in that lot ?

My genny has a L3E and I got a set of 3 from Diamond Diesels in Leeds for under £100 around 10 years ago.  Same ones from Mastervolt were quoted at  £75 each

Very strange. I took the glow plugs out of the Mastervolt (Mitsubishi engined) generator, only to discover that they are not Mitsubishi glowplugs?. They’re Champion brand and are the original plugs cos they have the same paint on them as the engine. I was always led to believe that Mitsubishi manufacture EVERY single part of their engines (down to the last bolt!), so I’m puzzled.
