Customer Question

Hi, I have a 99 Dyna 1450cc with no spark. I get no voltage to the coil. Would this be the ignition module? Fuses are good. I do get 12V with switch on but nothing when cranking over.
Thanks

- ignition power comes through the IGNITION fuse, through the RUN/STOP switch, to the center pin on the coil connector and pin1 of the black ignition module connector.

- follow the power with a volt meter and tell me where you are NOT seeing battery voltage.

we can continue then.

Hi Steve,
I do get 12V on pin 2 of the coil connector. The coil is new but does not fire. Any ideas? Can I ohm out pins 1 & 3? Thanks.
Expert:  Steve replied 1 year ago.

the resistance between pins 1 and 2 and pins 3 and 2 should be 0.5 ohms each.

I doubt the coil is your problem.

check the crank sensor, on the front of the engine.

remove it and clean, as necessary. replace if damaged.

while cranking the starter, you should see a small AC voltage on the connector pins.

let me know what you find.

I got a schematic and the only sensor is the cam sensor.
Expert:  Steve replied 1 year ago.

your engine has a cam sensor AND a crank shaft position sensor.

see post above and follow instructions there.

it is not likely the cam sensor would be fouled with engine wear products. in the absence of a engine trouble light, I wouldn't expect a problem with the cam sensor.

let me know if you need more help.
