tried to find old post about ignition switch problems from "Keyword" search to no avail. Can someone give me a reference to look up? My '26 just wont fire. Engine turns over good...getting gas to the carb. (Yeah I flooded it) Just no spark at the plugs with the giant-wooden-screwdriver test. Also the coils will not "sing". Was running great Christmas. In the past I have jiggled the key and turned it slowly until I heard a buzz..then I hit the starter and she would fire up and go. I know my computer hates me....do cars do that too?

Fred, with the key in the off position, it may be useful to run an insulated wire from the positive side of the battery directtly to the underneath side of the coil. If the coils sing with this, then yes, the switch and/or wiring are needing attention. Wouldn't hurt to look at the wiring block on the firewall on drivers side..rusty connections or simply loose?? Also, wouldn't hurt to verify timer is grounding properly. Time completes the ground circuit for each coil to fire. Could even be that the carbon brush (commutator) in the timer has dislocated. Hope this helps. Bill V.

My computer does that to me too.
I've made a policy of not keeping a baseball bat in the same room as a computer.
Less expensive that way.

Here's what I found; hope it's helpful to you:

A very useful tool what troubleshooting an electrical system is a volt meter. Turn the ignition switch to BAT and check for voltage on the bottom of the coil box. If no voltage, check the switch and conductors to the battery. If you have voltage, check that coils are being grounded by the timer.

Jim thanks for your suggestion. My ignition switch is a little suspect but by using your suggestion and follow the wires ect. I found that I have two coils that are bad. Sending them to Ron the Coilman. Thanks again.
