Re: 1996 mariner 15 no spark
O.K. but you really should go get a manual.
Your electrical system consists of a stator, trigger, switchbox, two coils, plug wires and plugs. Since neither coil appears to be firing the tests I would start with are the stator, trigger and switchbox.
On the port side of the engine to transom mount you should find your serial number. Please post that and I can look up the parts that are in your engine and get you the test spec's. You will need an ohm meter at a minimum to conduct these tests.
The only other alternative is to start replacing parts begining with the switchbox.
If this is an electric start, did you accidently hook up the battery backwards? That will blow a switch box.
