Tried to start our '26 Coupe today and found that the battery was dead. I put the charger on the battery until fully charged. Now the head and tail lights along with the ampmeter and dash light work but when I turn the key to Batt. to start it the coils don't buzz and the starter does work. I would appreciate any suggestions please.
With key on, make sure there is voltage on the connection on bottom of the coil box. Also, coils need a ground from the timer to buzz. With key on, slowly hand crank and see if you get a buzz at any point.
How long was it since the last time you ran the engine? Also how old is the battery? Did you do anything to the car other than charge the battery?
If the battery goes dead in one day, you either have a bad battery, or something on the car is draining the battery. To check for draining the battery, remove the positive cable from the battery and put a voltmeter in series with the cable and battery. When everything is turned off, you should get no voltage here. Try putting an ammeter between the positive cable and ground. You should read Zero ohms here. If you get a reading, lift each connection one at a time until you get to the cutout. you should have zero amps. Note if you get a reading at the batt side of the cutout, you have a bad cutout.
Do as Jim Wilson says. If you get no buzz, you have a problem in the ignition circuit. Check for voltage to the bottom of coil box. The timer should automatically be grounded through the engine, however, sometimes the ground between the engine and the chassis is not good.
I just had the same problem as you do. One of the forum members said to get a piece of wire with an alligator clip on each end. One end gets clipped to one of the terminals on the timer and the other gets clipped to the engine block. When you turn on the key to battery and the coils buzz it means you have a problem in the timer.
I have a starting problem too. I should be starting my laundry by now but instead I'm reading the forum!
