adjusting coils
Hello. I drive my 1915 touring almost daily just around town. I do ok with the mechanical end of all my cars and know a LITTLE about the electric side of an automobile. I would like to maintain and maybe start rebuilding my model T coils. I'm thinking of buying a ECCT. Do you think a person with limited electric experience could learn to use it? I really don't want to go to night school and take an electronics class. Thanks, bobt

Re: adjusting coils
From what I've read, eazy-peezy.
But then, I share ownership of an old fashioned HCCT that I found on the forum several years ago. It works for us. Our whole club is free to use it of course.
You may be able to find someone to check it on theirs maybe for a small fee, rather than putting out all the expense for so few times you will use it. Mike is cringing at me now!!

Re: adjusting coils
I have no electronics experience I bought the ECCT with the software. You do not need the software. You need the little hammer and that other piece to adjust coils. The ECCT does most of the rest. Then you just need practice.

Re: adjusting coils
Most important things. A good condenser inside the coil, clean points with proper gap, and set to spark at 1.5 amp. And no shorted or open coils. You can do this with minimum tools.
For the best timing an electronic coil tester or hand cranked tester will help you set these items and also test for a double spark. A single spark gives better timing and hotter spark than a double spark. A good final test is to plug your coil into the coil box of your car and see how it performs.

Re: adjusting coils
Apart from able to using a soldering iron you need no electronic knowledge to rebuild coils.
The adjusting with ECCT is mechanical - adjust gap size and bend the points to get the right single spark at the right dwell time.
But once the coils are set, you should not need to adjust them again until a long time. It may not be worth it if you could borrow an ECCT or if you where a groups that shared the cost.

Re: adjusting coils
Tim, If they start lining up to much at Mike's send them over to me. I have that home built one that I made. Jim

Re: adjusting coils
There is NO comparison between a HCCT & the ECCT tester in the quality & accuracy. I have used my restored hand cranker for many years. I took my adjusted coils & tested with the ECCT. I was supprised by what the hand cranker didnt show & the needed readjustments. Fortunately, I have access to an ECCT, thru a fellow hobbyist. I use my hand cranker for initial settings only.

Re: adjusting coils
I got lucky when years back a local fellow T’r contacted me through the Forum after a post similar to yours. I had already redid a set of coils and was a buzz box guy. Couldn’t believe the change a set of HCCT’d coils made in the car’s performance. No experience with the electronic units but I suppose they are OK too. As to rebuilding coils: very doable. I pop off the small side of the case where the capacitor is and go to town chipping away. Usually leave the glass insulator in place. Solder in the new cap use some wood scraps to fill the space and heat the same tar that came out in a can on the barbecue. Man does it stink. Outside only. I’ve done about 12 or so over the years usually for my own use. Haven’t had the need to buy any tar either but I do it on a tarp and reclaim everything. I never check the old caps I just replace them. Order your caps & points Before you start work. I could go on. As to the HCCT or whatever: I would really try to find someone nearby that has one before spending any $. Big investment.
Forget everything you thought you knew.

Re: adjusting coils
I strongly recommend the software option for the ECCT. With it you can test the performance of a coil 100 sparks at 400 rpm or 400 sparks at 100 rpm. You just plug in the numbers and press go.
I tested all four of mine 100 clicks each at 200, 400, 800 & 1600 rpm.
All four coils are tuned to match each other and there is an incredible difference in engine performance.
It is a great tool, well worth the money.

Re: adjusting coils
Initially I purchased just the ECCT without the software. When I purchased the software, it made adjusting the coils easier and more precise. Later I got the Mag software. I would recommend purchasing all software. I have 2 I timers. They are fantastic and very cost effective.
