BX2200D - No glow plug light

[adelphikos]

My glow plugs are not working. When I turn the ignition key to the glow plug position - the light on the dash does not light up. I don't hear any click of a relay, so I think it is the relay.

But I can't find the relay after buying a new one (16415-65600). Can someone explain where the glow plug relay is on a bx2200d?

Thanks.

Please do not be insulted but where did you get the idea your BX machine had a glow relay and second why that part number fit your tractor?

Messicks lists that relay for perhaps 20 models of Kubota and all are L series.

I do not think your B2200 has a glow relay. None is mentioned in the troubleshooting section.

Perhaps the D in your model makes things different than the WSM I have.

Is your glow indicator a small coil of wire you can see thru a small metal hole in the dash or is it a light bulb?

Adding to the above, even if you do have a relay, it's not time to replace it. You need to do some troubleshooting first. It could be a bad switch, bad connection, bad.... any of a number of things.

Don't load up the parts cannon yet.

Grab yourself a test light (or multimeter) and a wiring diagram and start poking around.

According to the WSM, the glow plugs are powered directly from the key switch, no relay in the circuit.
So either the bulb is burned out, or there is no power going to the glow plugs.
If you hold the key in the glow plug position, is there power to the glow plugs?

That's even better reason to not replace the relay!

The glow indicator is the second light on the dashboard.

First: Does the tractor start?

Second: Could the light bulb be burnt out?

Time to get a meter or test light as mentioned in a post above, and take some measurements to determine what is going on.

I'm interested as I also have a BX2200D...but no glow plug issues...so far.

Sorry for late reply... just double checked there is zero voltage at the glow plugs with the ignition key held in the warm position.

And the tractor is extremely hard to start in cold weather and starts fine in warm weather. Runs great once started, so everything points towards the glow plugs to me.

Not the GP's but rather the power supply to the GP's.

Test the key switch before doing anything else.

If you need a switch, I have a new one in the garage that I bought for the BX22 that I never used. Dusty

Test the key switch before doing anything else.

This, this, and this. Find out what is coming out of the key switch. If nothing, find out what is going in.

Measure, test, think. Don't just throw parts at it.

Where is the 19 Terminal? That diagram seems to show two AC terminals? Is it labeled wrong?

I agree something is wrong. Are there not identification marks on the switch body?
Ask DustyRusty to look at the switch he has.

Edit: I looked at the wiring diagram. It shows the wire colors for the terminals.

Dave_eng - - - If you look back at the Manual Page you posted.....bottom right is the key for plug diagram on the left side.....

Looks like Terminal 19 is the (1) location on the plug diagram, etc....

Does that answer the question? Wasn't sure if it did...pointing out just in case it helped.

Good call....... I was so focused on the mis labelled terminal I did not see the lower right.

The answer was there all along.

Oh good - - Glad it helped.

Ok, testing resistance off of (1) Black/Red and (4) Red, with key held in warm position. Saw no continuity (in any key position). So it looks like the switch is the problem.

Does the switch pass any other tests?

If there is a small hole in the switch body, spray a large quantity of any lubricant or cleaner inside. Then exercise the switch many times and check resistance again.

This should not be considered a permanent fix if it works!

I also checked AC Red/White (2) to 30 Red (4) and that only has continuity in start position. (And it should have continuity in the warm position.)

Just a follow up... It is now fixed. I replaced the ignition switch (66101-55200) and the glow plug light comes on and it started immediately in 25 °F (after about 8 seconds of glow plugs). Thanks for all the help.
