D1-30 Glow Plugs

[Alterboy]

GOOOOOOOOOOOOOOD morning,
My D1-30 B would not do anything when ignition and starter button were pushed. Fordham marine of Jacksonville spent 5 hrs. tracing it to the glow plugs telling the engine not to start. Question - Is $75 per plug a fair price....And Can I do the install . Are there any tricks and where are they located exactly ..
THANK YOU FOR ANY HELP

Re: D1-30 Glow Plugs

What kind of engine is a D1-30B?

The glow plugs don't "Tell" the engine anything, all they do is heat up the combustion chamber so the engine starts easier. If this is a Volvo 3 cylinder, I find it hard to believe all 3 glowplugs failed at one time. Easy to test.
First turn the key to the glow plug position, and see if you have voltage to all 3. If you do, remove the wires from the glow plugs,and with a meter check for continuity and resistance through each glowplug.
Is your engine EVC?

Re: D1-30 Glow Plugs

Thank you Don S for your reply. My knowledge stops at around a 70 volkswagon engine . I know just enough to get my self into a lot of trouble.
It is a 3 cylinder and I cant find anything that looks like a lead to a glow plug. would they be in a row andhave wires going to them ??? A VP certified relpairman is the one who told me they were bad .....it seems odd to me to . but we have checkedeverthing elseas far asI know . Again , thanks for the help.

You stated that you had no ignition or glow at panel. If your panel is not powering up, then the MDI box may have gone bad. check power into box.

Ahhhhh...5 hours? Was this a Marine Mechanic who might have seen a diesel before? Diesels are simple. Was the Certified VP tech trained in gas or diesel? Not being a smart ***, this is why you have diesels. If they took 5 hours, I would not let them touch it again. I cannot figure out how you can spend 5 hours unless they had 4 H and 30 minutes of travel time. Now that you feel terrible...this is easy to do. This engine has a problem with the brain frying. Your best tool to have is a volt meter, or you can break down and by a Power Probe III. Greatest tool in the world, Snap on Guy's sold them for $300 bucks, now there less than 100 at Amazon.

As Don said, glow plugs glow. They heat the cylinder to get it started. There are three components to a diesel. Air, Fuel and Heat. So if you are not having anything going, start at the battery, you should have power, its just an easy place to start. Follow the positive wire. Do you have an ignition key to bring power the the engine on? Check to make sure the switch is not shot.Put one probe on the wire going in, the other on the wire going out. Turn your knob to Ohms or the Omega sign. Turn the switch on, it should go to 0 on a digital meter and I forget on an analog meter as it has been so long. Check the solenoid. There should be a small 30A relay. Next go the the starter. Power there? Pull the plug out, Power? Next go to the back of the brain, power there? If so, your brain is probably fried.Your engine should be EVC. Is this in a J-boat? Volvo has an upgrade for the brain. They have had problems with this, one of those secret warranties. The brain does not like water, movement, banging. Good thing they put this in a boat.

Sorry...post pics if you are confused. The 70 VW is more complicated than the diesel.

Re: D1-30 Glow Plugs

So the engine is a volvo diesel by the looks of things, most smaller diesel engines have a toggle switch to activate them (you hold for a specifict length of time to warm them up)
Cars and trucks have a glow plug timer/temp unit that when you turn on the key the glow plugs will come on for a specific amount of time, but maybe this engine also has a glow plug module.
As for the glow plugs, you can find then usualy on the side of the head just beside the rocker cover.

I would remove them only after testing them with a meter, a dead one will have no continuity (like a burnt out light bulb)

They make only so many types of glow plugs, so if you remove it take it to an auto parts store and try to get them to cross reference it with another motor, usualy cheaper than the dealers variaty.
