MTFCA Forum

While I love 3d printing and have made many prints but in this application I have some concerns. Over the years I have discovered that most 3d printing is porous (leaky). They will fail vacuum leak tests, weap chemicals when plating, and not hold pressure. When installed on a vacuum leak tester it ...

We were out with the T the other day for a local car show and it rained hard in the afternoon. On the drive down the car was behaving very well (best it's ran in a long time) But after the rain we went to start it up and nothing.... Would not start. But what it would do was send a very noticeable sh...

Here is the schematic for my PCB, it should be compatible with both 3.3 and 5v logic (with the placement of 1 extra LED)
I have also included the kicad files if anyone wants to make there own or modify what i have made

Thanks for the info Matt, I was able to get all 4 coils running very well - all 2.0ms (+/- 0.05ms) I have ordered a 2nd revision of my coil driver board and a small STM32 based breakout board (see below) Screenshot_20240522-203811.png These should be with me in the next few days, hopefully I'll have...

Luke, Thanks for the reply, my plan is to get a full set of coils tuned in at 2ms TTF on the known working device. Then I'm going to move to a STM32 MCU (48Mhz) with USB support. It should give the following advantage. - Faster ADC reads at around 10-15 micro seconds (currently the audrino implement...

Ignore the low current reading (I have the 30amp sensor and forgot to update the configuration) it actually is around 5.5amp peak.


But is this an example of a double spark situation?

PCB all made up, all waiting to assemble it inside the casing

Shane,

Good to see some life still in this project, it will be interesting to follow your build.

Are you planning on making the boards and/or design available to all?

Luke.

Absolutely, once it's tested and confirmed working, all schematics and firmware code will be available here / GitHub.

Currently starting a build of a FACT coil tester, my aim is to make 2 new versions. 1) generic board with the MOSFET driver + current sensing + capacitor sensing components that can be connected to any 5V MCU (picture below) 2) an "all in one" PCB that has an STM32 TSOP20 package that should have an...

Hello,
you already got a lot of good advice, and maybe you already checked that, but still just to make sure: Did you check valve clearance..?
Regards,
Frank

Not yet, looking at the advice it's probably worth another loot at the ignition and fuel system.

Shane you typed something that caught my eye. What fuel filter are you talking about? The stock one made by ford, which is nothing more than a brass or steel bulb screwed into the bottom of the fuel tank that has a fine brass screen inside that the fuel passes through going directly to the carb or ...

get the coils looked at get someone to verify carb setting renew wiring if it's old/crusty rebuild the coil box and key switch verify your band adjustment the car is going to run, and the more it runs, the better it will run. And with the plug sending out spritz of oil, the car is unlikely going to...

Does the engine have a fiber/composite timing gear? They can fail and cause the cam to get out of time. Bad insulation in the coil box can cause an otherwise perfect engine to run like a total junkpile. Problems with coils and/or coil adjustment can do likewise. A malfunctioning timer can seriously...

What is your oil level? You want it NO HIGHER than the top petcock, and ideally halfway between the top and bottom petcocks. You want 1 US gallon (4 quarts, or 3 3/4 liters) total. The oil is at a level it flows out of the bottom tap and not the top (maybe 1-2 drips from the top of the car has been...

WHEN THE CAR IS RUNNING IN NEUTRAL IS THE ENGINE RUNNING SMOOTHLY? Even if the engine is worn out the car ought to run a least 20 MPH on level smooth ground. Also mentioned is the car is screaming in low and even if it’s smoking as you say it ought to run close to 30 on level smooth ground. Have yo...

If you fully close the needle on your carburetor and then open it up how many full turns do you set it at for cranking & running? Have you inspected the Venturi for any cracks? Not an often event but I do agree with Pat on the 10 mph in low, I bet the motor & transmission are screaming. Its somewhe...

If you get the coils adjusted properly and the ignition system in order, you may find that this engine runs better the farther you drive it. The trick is to get it to run on all four cylinders, then drive it on the open road at moderate speeds for dozens of miles, keeping a close check on water and...

I suggest you contact Richard at T Service who are based in Weston-on-the-Green in Oxfordshire. They have a website ( https://www.tservice.co.uk/ ) and a facebook page. They look after all my early Fords from 1904 to 1915 and have the highest standards. Give Richard a call. 01869 351006 Regards Joh...

I added about 10ml to each, but like I said number 1 already had way more than that sitting on top. Testing was done with the throttle fully open, checked each one three times (did 5 cranks on each test) Hand cranking with the plugs in does indeed feel uneven (1 is needs more strength than the rest)...

Thanks for the suggestions I'll get more resources to test the coil boxes (or send them away to get looked at) We checked the exhaust manifold this morning and can't see any blockages Also did compression tests : 1 : 48psi (loads of oil pooling on top of the piston) 2 : 35psi (45psi with oil added v...

Assuming I did make things worse with the coils, what's the best way (from home) to set the gaps to something that will work ?

I'll check the exhaust manifold this week

Will do a compression at the same time to rule that out

Whether coils out of adjustment are the cause of your problem or not, I would have them checked and adjusted by a pro. Tuckett Brothers are only about 125 miles from you. It actually went to them (the full car) about 2 years ago and they gave it a once over and it was still running pretty bad when ...

So I think I have ruled out the ignition system I followed that guide at 1st to re time the engine and didn't get many gains in terms of power, since then I have used the "straw in #1 cylinder to get to TDC on compression" method. Both end up in around the same. We have moved the coils around and en...

Hi All, New to the forums and looking for some advice My grandfather has a 1915 T and it's been not been running very well at all (low power)..... in low gear we can get 8-10mph and *if* it we can get it into high it tops out at 18mph (full throttle and between 3/4 to full advance). Mild hill climbi...
