beru glow plugs

I have read a lot here about the beru plug. I have read a lot here about the motorcraft/beru plug. I asked at different parts stores for beru plugs and they go-" huh? ". At the local dealership I got the same response-" huh? ". I have read somewhere in these forums that it is a marine grade, constant duty glow plug. Is a motorcraft a beru plug? The last set I bought were motorcraft, and the boxes/baggies said beru on them nowhere. After this last installation of plugs lasting approx 3 weeks I said screw it and I use the ether. No worries- the system is wired to a pushbutton, equipped with a light so I know there is no power to them. This may sound like a dumb question, but where do I go to buy this beru plug, without them looking at me like I'm nuts? I know that the last set(motorcraft) were never cycled longer than 9 seconds at a time-three weeks and I had $90 worth of bad glow plugs. What say you guys?

Hello, I live in Halstead, KS, not to far from you. Cool.
Anyways, to answer your question. Go to autozone and get the ZD-9 Motorcraft plugs, they are $9 each. They are the beru plugs. Im not sure what beru plugs you had... there are a few diferent ones, ZD1A, ZD9, ZD11... and so on. You want ZD9, and autozone has them in stock. They should last a while for you.

Thanks-how far out of the kc metro are you? Armed now with numbers I will try advanced first. Just because I finally found a parts guy who seems to have a clue, even if he drives a duramax. Anyway I'd have to go a ways to get to an autozone, and O'reilly's has dropped the ball way too many times for me. Also, what type of head do those have on them? Mine are the old male spade type.

Hey I just looked at your rides-I'm having troubles with the signature on here- we ought to get along alright-I noticed you had a sixties truck. I have a 65 f100 2wd with a 352 three on the tree, It is pretty quick, has lots of mods, that would be my toy, my diesel is an 83(85 motor), F250 on 38 inch swampers. I also have an 85 bronco and a 98 explorer, best little truck I've ever had.

Ummm, I'm pretty sure the ZD9 plugs are for the 87 and newer motors (up to 93 maybe?). From what I gather they have a "bullet" type connector on them.

Anyways, if this is for cfrives3 truck that has an 85 motor in it the ones he wants are the ZD1A. They have the flat "spade" type connector.

cfrives3, from what I've read not all Motorcraft plugs are Beru plugs. The ones that are have the words "Beru" and "Germany" stamped into the flat metal ring around the body of the plug below the threads but above the skinny part that actually gets hot (heating element)....

Right on! Time to talk to smitty down at advanced. ZD1A and make sure they say beru on them. Got it. What exactly does constant duty mean though?

Constant duty means they can be turned on and left on. In our trucks they aren't rated for constant duty though. Turn 'em on and leave em' on and they'll burn up in a minute or so. I've read that they are really designed to be used in a 6 volt system - which is why they heat up (and burn out) so quickly in our 12 volt systems.

I have read that if they are immersed in liquid they can be left on continuously. On some of the sites for people burning veggie oil there are instructions on how to make a flow-through heater using a glow plug as a heating element. Maybe that's where the idea that they are continous duty came from. Or maybe in a 6 volt system they are rated for continuous duty. But not in a Ford/IH IDI...

Yeah, 8-12 seconds should be enough - depending on temps and how easily your particular truck starts....

the MOTORCRAFT/BERU ZD1A is for pre 87, and the ZD9 is after 87.
the 1A uses the male spade connector, and the 9 uses the bullet connector.
with the glow plug controller working in my 88, only 6 to 8 volts goes to the glow plugs. that is why they last so long. the problem with a push button and no controller is that you are now putting 12 volts to the plugs, so they will burn up very easy.

Cool - you confirmed everything I said in post #6 above - so I guess I got it right! See, I'm learnin'

You sure on that? If so the 88 controller is even MORE different than the 87 and older version like what cfrives3 and I have on our older trucks - more different than I even realized.

I knew they changed the controller style and glow plugs in the 87 & newer trucks, but I didn't realize they dropped the voltage coming out of the relay. In our older trucks the GP relay draws power directly from the battery and when the relay is energized (by the controller) it puts the 12 volts from the battery directly to the GPs. So how dos the newer system lower the voltage? Is there some kind of big ballast resistor or something in parallel with the GPs to lower the voltage?

i have no idea how it works, just that it does.
my wait to start light stays on for between 15 and 30 seconds, depending on how cold it is outside, and when i put the glow plugs in it last year i did the voltage check a few times, that is where i got the 6-8 volt numbers from. for all i know it may be that it should be 12 volts, but they work fine, so i ain't gonna mess with it.
here is a pic of my controller.

I just make a small camp fire under my truck each day and it warms the block up nicely. Dave S. would agree.

Talked to smitty at advanced today. They have 1 store (in texas) that has them or can get them. They carry the autolites. I said "no thanks." Anyway, as I am addressing my problems with oil pressure first, I am going to wait and see how much luck Davelong667 (I think it was) has with his new ebay glow plug purchase. Was the brand name WAP, or something? If I remember right, he also has his system set up on a push button, and I'd like to know how he comes out on his. I guess I need to check voltages at the plugs and such. Some one was saying they only get 6-8 volts at a time, not 12. Maybe that's why I am burning mine out so fast, but when I installed the push button system, I followed the instructions to a T. Even when you do this, isn't there still a relay that reduces the voltage a little? Info and opinions always welcome- Holler back!!!
