There is a red/white and a blue/white wire coming to the swithbox that seems to feed plugs 3 and 4.With the motor running, when I check for resistance I get a reading. There is a red and a blue wire coming to the switchbox that seems to feed plugs 1 and 2. When I check these I get no resistance reading. I know it is not the plugs or the plug wires. This test on the switchbox is as far as I have gotten. Truthfully I do not have a clue what I am doing. Is this something I can fix? Or am I better off paying someone to fix this. Any feedback will be appreciated.
<br /><br />You need a certain kind of test meter to check a switchbox. Most Merc dealers have those. Your option it to test everything else and see if any of those are the problem. The reds and blues are paired. There should be resistance between the reds (high speed widings), but not to ground or the blues. There should be resitance between the blues (low speed windings), but not to ground or the reds. All of the wires have to be disconnected from the switchbox for testing. But that's not your problem. Those wires make power for spark. If you have spark anywhere, the power is being made.<br /><br />Your most likely problems are the trigger or the switchbox. You can test the trigger(s). I don't know the procedure off hand. Your public library may have a manual that would help. Or you can order one above.
