T We celebrate on the Oldcar Festival in Aarburg the Route66 unfortunately it rains very hard.
After 2 hours staying in rain the engine runs just on 2 cylinders. I have taken out the ignition boxes
3 hours later the engine runs on 4 cylinders again. Did someone have the same problem?
Thanks for your help Stefan.
No problem with my John Regan, Fun Projects Kit rebuilt coil box. The plastic does not seem to absorb the moisture like the old delaminated plywood did. Just a tip and an inexpensive and easy afternoon project.
Your coils are shorting out because of all the rain and moisture. When you took them out they dried out and you no longer had an issue. This is common when they get wet. Sometimes carbon tracking will also cause problems. You can clean and seal your coils and coil box but one of the better solutions may be to install plastic coil box kit as mentioned in the other post. The plastic does not conduct the electric current so you no longer have a misfire in the rain.
Follow Jon's advise and buy a Fun Projects coilbox kit. @funprojects.com

Since the wood in your coil box most likely got wet it could have already established some carbon tracking on the wood which could cause you future problems.
Great looking T you have!
OK Dennis you type faster!
Rain has always been the bane of the Ford ignition system, until the Improved Car in '26 when the coils were mounted in an enclosed flat top box, with gasket-lined lid on the engine under the center of the hood.
Water wets the plywood box coil terminal panel, leads to shorts in the high tension output of the vibrator coils, and causes hard starts, and misses.
Now back in the days the Ford was new, you could try to prevent the loss of ignition in the rain with various products to protect the coil box.
Cover the hood and cowl at the gap to stop the water from entering.
Or place protection between the box and dash.
Or put a rubber boot in front of the coil terminals to stop water ingress.
But today, our happy, tour-savvy T'ers just contact Fun Projects and get rid of the wood, and go wet-free plastic, and no more ignition worries from getting caught in the showers.
Mine did that too on wet Hillbilly Tours. Then I got The John Regan/FunProjects Rebuild kit and solved the problem.

Great posting Dan! Acknowledged a common problem, showed us some of the old fashioned remedies and then the best and final fix of them all! Thanks for the pictures. I have Fun Projects kits on my 23' and 16 Touring coilboxes.
Thanks to all for you help will order from John this Part I am sure it works
Wowzer !! . . . GREAT C Cab TT on your profile Stefan, Another, more immediate fix for your problem is to unbolt the cowl-to-firewall fasteners and shoot a trail of silicone between the cowl and the upper firewall - above the coil box
Stefan, another option is to get some plexiglass and cut a replacement for the wood in your coil box. The wood in your box makes a great pattern.
You will need to recess the brass contact area on the back piece but that is not hard to do.
I did this to several of my cars many years ago and have not had a problem. (probably long before John offered those plastic replacements)
