I have a 1993 90HP Evinrude model number VE90TLETS
Tach does not work
Battery is not charging when engine is running at any RPM
Rectifier/regulator on top of engine
Can it be replaced without removing flywheel?
What is best way to test it? How can I test the stator?

Disconnect your outboard's battery.
Disconnect the rectifier leads from the terminal block (note locations of each lead). Connect the black lead of your continuity meter to engine ground. Set your meter to ohms scale. Connect the red lead to each lead of the rectifier one at a time, note if the meter shows a short (almost zero ohms) or almost infinity ohms. Write down which leads showed short, and which showed almost infinity ohms. Now connect your meters red lead to engine ground and do the same test with the black test lead to each rectifier lead one at a time. Write down which leads showed short, which showed almost infinity ohms.

Now compare results, each rectifier lead should show either almost no resistance or almost infinite resistance with on color test lead, and then the opposite resistance reading with the other color test lead. If the reading on a particular rectifier lead doesn't change no matter if the red or black test lead is connected... it's probably shot.

It's not uncommon for the older rectifiers to burn out. You can replace yours online for under $90.

Don't know if you have to remove the flywheel on your particular model... sorry.

It sounds just like the problem with my 1980 Johnson 100.

Rectifier solved it and it was around $40 ...no sweat.

Hope this link works:-)
