1988 88hp Evinrude no spark

[Bill Gramm]

After replacing a lower end and tilt and trim unit on my new (to me , at least ) 88' 88 hp, I got 5 glorious days of fishing. On the last day it ran, after shutting it down for a swim, it would turn over strong but not fire. After taking the cover off, I noticed that the flywheel felt unusually warm, almost hot. I checked for spark and had none. I pulled 2 plugs and they were wet with gas. I disconnected the kill lead to eliminate the ignition switch, jumped the starter, still nothing. Later, after multiple resistance checks with an ohmmeter according to my OMC manual, I have determined that my charge coil tests open, Wouldn't' it be shorted if it overheated? I assume I must replace the stator assembly. Any thoughts?

Hey, someone must know the answer BG

Not neccessarily Bill. The charge coil is only one coil in the stator. The stator is mostly taken up by the coils that create the power for recharging the battery. A lot of the heat you feel is from the engine. What you also need to do is, if possible, read the voltage from charge coil with a peak reading volt meter. This would determine for sure if the charge coil is bad.

Look under the flywheel and see if you can see any "goo" laying around under there. If a stator really fries, the potting material sometimes will melt and lay around under the flywheel.

Thanks for the reply. I was starting to wonder if I had done something wrong on my entry. I do not see any evidence of any melted potting material. If I put an ohmmeter across the two charge coil leads, I get no reading. I am using however, a fairly good Micronta multi-meter. What kind of meter would you suggest I use for the test you discribed?

How likely is it that the connection between the pin connector and the wire fail?

The output test is really the best way to check charge coils. But if your confident of the test equipment, an open reading would indicate a faulty coil.

A break in the leads do happen on occasion but usually in wires that move with the timer base. The stator doesn't move so I would not suspect a break unless the wire got fried for some reason.

Thanks OBJ, and I hope you stay with me here. I do have to get to work. What kind of meter do you suggest for these more technical tests. I'm sure I'll need it in the future and it will surely pay for itself this first time. And as far as confidence goes, I'm new to this and am winging it off the seat of my pants. I'm just following the manual's instructions. And I also get the feeling you think I might be looking under the wrong stone with the charge coil?
