96 Evinrude 20 no charge

[Skiptrace]

Charging coils and what I think they call ignition coil were bad. Broken wire on charging coils and ignition coil was melted. I replaced those and the rectifier as that was testing bad as well. With everything connected it still not charging the battery. Voltage exactly the same running or off. Replaced battery as well. Connections clean and tight. What am I missing?

depending on engine mdl#... please post it

check for AC volts on yellows... if none charge coil is suspect . make certain rectifier is grounded (black wire if so equipt'd )

you can get 2 or 3 phase rectifiers dirt cheap on AMAZON if only for testing purposes.

There is a fuse in the battery charging ckt ? Mine is 35 amps in a yellow 1" X 1" case. 1986 30 hp.

I have 4.5-5 volts ac the rectifier is bolted to the frame (ground) of the motor. Good ideas I'll get another cheap rectifier just to eliminate it one more time . Thank you

I don't think so. It's not in the wiring diagram but I'll look closer. Thank you

5 vac will never give you 12+ volts to charge the battery!
if 2 wires of the charge coil measure across BOTH wires! not just yellow to grd.

I read the title and figured your were giving away a motor
Just kidding, I had to.

Yes I just did not run it up high enough.When I run it up I get low teens. With new regulator I also get some charging voltage but not the 14+ that is expected. Battery at rest engine off supplies 12.7 I am able to get 12.9 at 2/3 throttle guessing 2500 rpm.

E20eleda is model number

It can take days of medium running speeds to recharge a boat battery up to 13.7 or 14.5 volts. Any fishfinder will take longer. If possible at lower speeds.

I never see charge voltage out of the rectifier. Running I never see a voltage higher than the battery voltage unless I'm at almost full throttle. I have rechecked charging coils, rectifier, wires and they all check out with a meter. I get ac out of the coils about 15 vac but it Needs at leashalf throttle to get it. On the output I never get anything above battery voltage until I'm well above 2500 rpm . Looking at diagram I see nothing else that impacts. Stuck for what is the issue.

If you have a BIG car battery SIZE like larger than a size 27 ?
You need to fully charge the battery with a real normal sized battery charger. It could take several hours at10 to 15 ampsCheck water level in each cell. add if needed.

Done that. I've been doing that for a long time. Every trip out I recharge the batteries. It's a deep cycle marine battery.

Ok so you cannot trust a new rectifier even if it checks good on a meter. I replaced again and it's working. Thank you everyone.
