I have a 1985 Evinrude V4 90 with tilt and trim with a 9 amp stator.
My regulator appears to be fried. Stator seems good no black goo and AV output at 1500-2000 was over 15. At battery no voltage change and with accessories on battery goes down.
I understand that the engine only needs to battery to start after that the engine can run with out it.
No out put by regulator at 1500 rpm or greater and Tach is works but bounces around at when it reached 4500 RPM.
I did have to replace the Thermostat and the overheat buzzer has gone off a few times the unit is a CDI 35 amp dated 2001
My understanding is that the reason that the higher 9 amp stator and regulator was used because of the Tilt and trim models.
I was thinking replacing the present regulator with later model since it is significantly less costly.
A couple of questions , that I do not know the answers and could use some help.
1. Will a 91+ 10 amp water cooled regulator( part #0584204 $76.27) fit and function as a replacement for a 35 amp unit ( part #0395391 $207)
Why would you need 35 amps?
I read a post on Continuous wave that you could use the newer one.
2. The regulator has 5 leads 2 yellow(yellow and yellow/ gray), 1 red one purple and the gray. I know that the gray is for the tachometer and the red is for the charging the battery. I think the 2 yellows are for the AC from the stator to the regulator to change to DC current and the purple goes to the starting circuit. The unregulated uses a 3 wire rectifier
3. I think the fried regulator is affecting the function of the Tachometer and of course not charging my battery , but my understanding is that the Gray transmits the signal from the alternator. I think that is the yellow gray wire coming out of the alternator. I do not think it sends high current.
What does Regulator/rectifier have to do with gray wire?
3. What effect would a fried regulator have on the Trim and tilt? does the Trim tilt work off the battery or the alternators AC or both?
Any input or wisdom would be appreciated.
I have searched the forum , but have not found the answers to these burning questions.
Thanks
I have included photos of the wiring diagram and the two regulators the one with the gasket is the 35amp and the other is the newer 10 amp
