    I have a ’94 Guilin with a 2 cylinder diesel . It has a glow plug with a fuel line hooked to it to help with starting . I am wondering if anyone knows how these are supposed to work. Mine just burns up the circuit breaker as soon as power is applied.

    What those are supposed to do is build a little fire in the intake manifold, and that provides hot air for a starting aid. There should be an igniter (similar to a glow plug) and a small reservoir for fuel. I have seen and heard of these plumbed in various ways. Sounds like you have a defective igniter. If you can't locate an OEM replacement (if you want to), you cal always go the aftermarket route.

    Think twice before using ether as a starting aid.

    Here is the pictures I took of the glow plug thingy. I don't see anything wrong with the parts. It may be assembled wrong. It has a small fuel line that attaches with a B nut and a single wire going to a momentary switch on the dash.  The whole thing is screwed into the middle of the intake manifold.

    Hard to tell from the picture if it's assembled incorrectly, but it should show some resistance on an ohm meter instead of a dead short. What amperage rating is the fuse/circuit breaker that it's connected to?

    Excuse my ignorance, but what is a “B nut”?

    I get 1 ohm through the coil but when it’s assembled,it reads .2 ohms.
    I think it is hooked to a 20A fuse/wire.
    Sorry, I have an aviation background and a B- nut is what we called the nut that attaches the hose to the fitting. As in a flare fitting.

    Courious about an after market part. Where would one get one?

    Here are a couple of leads. Ford / New Holland uses the same setup, but I don't know about thread sizes. You can also check with Affordable or Circle-G, they are OEM dealers and may have these in stock.

    For some reason or another I cannot post links. They don't come through complete. Anyway, just Google “manifold heater starting aid” and you'll see.

    You might also check the wire size to the heater Chinese tractors are notorious for under-engineering their electrical circuits and components.

    I would like to know the min. temp is required for one of these to work .I have one of these on my jcb backhoe and I would like to test it with a digital lazer temp gauge. In the instruction book it says not to engage heater for more than 15 seconds .I have had issues with starting with temps below 40 f. I was told that some engines you can hear a pop when it ignites. I think I will put a amp meter inline to see the draw of the heater coil.
