Tractor Glow Plugs

iirc, should measure a shade under 1 ohm.

change all 6, as they are a bugger to change, as in true BMW style, all the bloody inlet has to come off. Officially, that means you should change the 6 inlet gaskets as well, though every time I've ordered them, its taken dealer weeks to get them, as have to come from beemer.

Sounds a bit low to me.........dunno on omega tractors......but under an ohm...is a massive current for the battery to maintain all 6 glow plugs........even for 5 secs or so  :-/

Remember you are testing them cold. Resistance rises as they heat up. 1 ohm gives 12 amps ish peak current which then tails off as they heat up. I reckon that's not far off.

Either way, best to check on a battery in case they go open circuit when they get hot.

I didn't know you were supposed to take the inlet off? I did mine with it still on, was very tight, but do-able.

Suprised you managed to get a spanner around the injectors and fuel pipes.  I reckon even a Tunnie would struggle with that one...

If its alot better with the manifold off, then I would recommend that! If you leave it on, it involves a deep socket and alot of knuckle joints and extensions from a 1/4" set. Took me a morning to do - the central 2 were horrendous.

Takes me about 30mins to do all 6...

Oh ok... my way was defiantely the hard way then...
Shouldn't have to do them again for a while though - hopefully.
