Motor question.

So Did the test . Meter was .2 ohms . With metal strip removed terminal to ground was .8 ohms .8ohms .8ohms and 6meg ohms.
So I have a bad glow plug. Do I replace all them ? or just the one. Seen on line where they say to do both. Change them all or just the bad ones.

I would just replace the one, I'm cheap.
with 2000 hours depending how many starts it's questionable.
But I'd just do one might buy 2 to have a spare with winter coming on.

My Branson 4220 has always smoked a bit at start up, and it clatters, too. When the engine starts from cold it usually takes a few seconds, five or ten, for all four cylinders to get hot and cleanly burn all the fuel. If the engine is starting readily, not requiring long periods of cranking, then your glow plugs are working.

Just as a test, one morning when the machine is cold, just crank it without letting the glow plug light go out. It'll start, but it will take quite a bit of cranking and you'll see a lot more of that gray smoke. I sure don't recommend doing that as a matter of course, it's hard on the starter, but it will give you a frame of referrence.

Yes I know the normal noise and smoke..... This is different. . When your gets this way you too will look into it.

I like the idea to get a spare one . The dealer is 2 hrs away.

IMO, depends on how much they are... If cheap replace them all.

Whats cheap

They aren’t very expensive. I’d probably change them all and keep the working ones for spares.

 

[4570Man]

Whats cheap

I think they’re like $10 each.

 

[rasorbackq]

Find out tomorrow . Didn't think anything was $10 for a tractor. Seems for me its always $300-$400 for parts.

I was right not going to be cheap $38 ea bought 2 one for a spare. Installed and running correctly again.
The bolts that hold the buss bar on were a pain to get on . Especially the back one nearest the seat.
Thanks for the info guys
