85hp evinrude 77' model, how can I tell if the ignition switch or the kill switch is bad? The motor wont even try to turn over and the batteries work (new) previously when the key was turned the motor would click and a buzzer would sound. Now, it does nothing.

Re: Ignition Problem

You need a wiring diagram (service manual) and a multimeter to properly troubleshoot the system. If you don't know how to use a multimeter and read electrical diagrams, you should be learning how to do that before learning how to fix motors.
The other option is to do like most people and start throwing expensive parts at it.

Re: Ignition Problem

FR is right. Get a service manual and save yourself a whole bunch of headaches on this project. You've got an old motor and there will be plenty of other uses for your manual:) Get an OEM manual, as the after-market types can have mistakes and confusing instructions because they try to cover a whole group of motors at the same time. I made the mistake of using one of the after-market types at first.

Your starting problems can be a result of many different problems and you need to follow a set of troubleshooting instructions that will walk through everything in a logical manner instead of taking a shotgun approach. In the long run it will most likely save you a lot of money and time. Your problem could be as simple as a bad battery or loose connection, blown fuse, or more complex like a defective part in the starting system or a bad ignition switch, kill switch, etc. The only buzzer I can think of, would be the overheat warning buzzer in the controller. So you could be looking at a problem with the sensor or a short in your ignition switch or wiring. Lots of choices here.
