It literally warms my heart that you and others have used this posted thread to manufacture your very own bullet proof PCB. You’re using the thread exactly as intended! :giggle: For all future visitors, post#51 has the clear schematics that will allow you to bypass the PCB/EESS forever.

My schematics show an external LED that you can mount anywhere. You can also disconnect the “wait light” from the dashboard system and connect to my box’ designed LED wires. Use Packard Connectors from my box to the stock “wait light” wires. Just make sure you get the polarity correct as LED’s...

Agreed about that being a Prestolite. I have several that I opened before creating this thread. Prestolite has robust solenoids that can be reused for a DIY project. Self tapping sheet steel screws will close it nicely. Drill the top hole larger than the bottom so the screws act like lag screws...

Happy you did this! Good on ya’! The LED I included in the diagrams is to show if the glow plugs are functioning. If all 8 are dead, my LED won’t light BUT the dashboard “Wait Light”/LED will. Happy to see the relays you used will support 200 amps each. Where did you source them and are the...

Hey, I confirmed these diagrams with you months ago Cam, so I blame you! LOL [EDIT - And yes, you're correct.} My unit works so the diodes are in properly. I will correct later tonight, but I clearly wrote a disclaimer.

Well. Here it is. I made one and it works... BUT: This is a potentially dangerous high-voltage high amperage item and let me start by saying that I made this as an educational learning exercise and none of you should do it. I am not an electrical engineer nor am I affiliated with any...

I will post my diagrams later. I have a video to post BUT it is not edited. Your diagrams Sellers are rudimentary. Not a bad start though. I have the circuits totally mapped out BUT I have been busy managing patients and my practice to post or post the video. The Chinese Virus caused me to...

Pig9r, I want to go one step further. Press a button and count to “10 Mississippi” and then let go and twist the starter lever. No automated timer device needed. Just a switch and a knowledge of how to count. In my LandCruiser there is just a glow light that tells you your glowplugs are warm...

madeinusa... You talk about hiding behind a keyboard? Besides cursing in a family friendly forum... Initially your signature line said Utah, then when confronted you changed it to Dallas. You have been ignored.

madeinusa..... You're a new member who only posts about this one product. You posted this same crap in Feb 27, 2020 with the same link, and again like 6 times. These have been your ONLY posts since joining. YOU are the seller trying to troll this forum and drum up business. I don't appreciate...

RWH is correct. This FleaPay Guy is charging 300 clams for a glowplug controller sold in Australia for 53 dollars AU( maybe$42 American). He then jacks up the price of the repair astronomically based on this. I would stay away from the FleaPay guy as he/she is behaving like a crook. (I would be...

Seems like you want to make your own glow plug switch. That has already been built by another member. There is a thread by that other member about making a separate glow plug harness. I will look for it later or another member can post. Best, T

Now that I'm back from watching my Giant's win on Sunday AND from overeating turkey yesterday, I'm back to my project. I am wondering about the glow plug controllers. When I was a Saab guy, there was a doodad that acted as an actuator for an electric choke. It measured block temperature. When...

P.S. I can certainly use a few more old Prestolite boxes! Some damaged components in mine are not identifiable. Please PM me if you have any. T [EDIT] - I also request two or three dead or working AMETEK PCB units for evaluation. Please PM me if you have any for donation or sale.

I opened an old Prestolite box today, and it further confirms my suspicions. It contains 3 relays and a circuit board without any integrated circuits. Looks like one relay is for ignition and one is for glow plugs, and one is for general electricals. Reminds me of the story of the brilliance...

Amazing post AND seems to confirm my suspicions about function AND bypass! Many thanks!

Essentially, the more I dissect the more interesting this thing gets. Essentially the PCB is a decision engine. If glowplugs are OK, a decision is made to power them up. If they power up properly, a decision is made to allow the starter solenoid to engage. At the same time a decision is made...

I'm beginning to think I also need an old Prestolyte box for evaluation. Is there a vendor here with one? EDIT - Found a dead one and bought it. More would be better to compare live and dead parts.

So how do we get the schematic diagrams AND integrated circuit board pics from the manufacturers? Where do we get the military technical specs for how a PCB is supposed to operate? Is this a "Freedom of Information" thing OR is there a department within the DoD we can write to? Will the...
