first model t and i have a lot to learn
turn the switch to battery and the coils do not buzz. took coil box out , clean contacts on box and bench checked the coils . 3 will buzz and have spark one coil is dead . using a test light i have power from battery through switch , through box ,through coil and out of terminal and through to the timer.
what should i check next or should i try to start on mag and then switch to battery ? are they suppose to buzz when switch is turned on to battery , will they buzz if switch is turned to mag ?
be careful not to put any voltage with jumper wires etc. to the mag terminal, or it can make your magnets on the flywheel magneto dead. you want to start on battery, then switch to mag after its running. coils will not buzz even when you crank over by hand? each one should buzz when it turns to its time to fire by the timer. will not buzz on mag at rest, but a good mag will start the car when cranking they say! i've not had one
Glen,the coils won't buzz on the magneto unless the motor is running. They ought to buzz when the switch is on battery. Check the commutator and make sure it is clean. Then maybe take the coil that does work and exchange it for the one(s) that don't work. Fairly simple system albeit a peculiar one. Make certain when testing your coils on the bench that they are under load by having an earthed spark plug connected or they will all be damaged. Hope this helps, Chris
Give me a call 10AM to 5PM EST when I am in the shop. I will walk you through a simple routine to determine where the trouble lies.

Take Ron up on his offer. You won't find anyone more knowledgeable in this area.
Whether a coil buzzes or not when you turn the switch to battery depends on whether the timer is in a position to complete the primary circuit to ground. It just depends on where the engine stopped, so no buzz when switching to battery is not necessarily a cause for alarm. However, you should hear them buzz in secession as you turn the engine over. They do not buzz on magneto, even when running. It is more of a clicking sound.
Give Ron a call. You'll be glad you did.

About the Ebay coils just pay attention rebuild very often means just cleaned up. Send your coils to Ron he will be pleased to rebuild yours for a good price.
Maybe it's only me but are you giving up a little quick?? You should be able to find someone close to take a look or is this about selling? Bud.
A Model T is one of the easier cars to work on. It does have some unique features such as the ignition system and the transmission, but the Ford manual and the club publications or CD's will lead you through maintenance and repair of all the important parts. Don't give up.
What you need is to find a few good coils which have been tested, then when you have a problem with yours, substitute a known good one and see if it fixes your problem. If you can't afford to buy any more coils, find someone in your area who has a Model T and borrow his coils to make the test. You can also verify that your coil is bad by trying it in someone else's T.
Your closest local club will have many members who are willing to give you hands on help.
