I am getting "Irregular signal" on the Pulser coil readout

Customer Question

I am getting "Irregular signal" on the Pulser coil readout using Yamaha YDS software on my Yamaha F115 TXRA. Also under Diagnosis records I have listed "Pulser Coil". Can I assume that if all the connections are good that the Pulser coil is Bad?

Hello Breny. My name is***** are correct in your assumption. Irregular will cause engine performance issues. Check all grounds as these are areas that get neglected and are the cause of irregular readings. If everything is clean and tight the pulser coil is bad. Post back with questions.
