Hello all, so I'm working on a 25 TT for someone and the coils are not buzzing. They will buzz when I set it to battery and turn the engine over. The 6 volt battery I used only had like 3.5 volts in it so is that the issue?
First, you have a dead battery.
You say you set it to battery and they will buzz. That's how it should be.
What setting are you using when they will not buzz even though you expect them to?
When I turned the switch to battery they would not buzz but then when I left the switch on battery and turned over the engine they began to buzz.
That is normal. The engine will not always stop with the timer's rotary flapper or roller on a coil contact. Once you hit the starter tho it will be making contact as it rotates and hopefully your engine starts John.
Another possible test before you try to actually start the car is get a screwdriver and see which plug is firing. Touch a non=painted spot on the cylinder head next to the plug and complete the circuit to the plug with the metal part of the screwdriver. DO not let your fingers touch the metal part of the screwdriver while you are doing this as it will light you up.
You can turn the engine to the next buzz till you have determined they all fire. If you turn slow from buzz to buzz, they should be in firing order. 1,2,4,3 The first one will probably not be #1, so follow from which ever # and do all four.
Oh, I forgot,You are looking for a small spark as you touch the plug that is being fired.
I see this "normal" condition a lot because my key switch makes somewhat poor contact when on the battery side so, it can be often hard to tell when I hear no buzz. What I do is turn on the key as best I can and then turn the hand crank just a bit slowly until the coil buzzes. Then I swing the crank to start.
BTW. You will never hear your "coils" buzz but, you will hear your coil buzz.
