replaced rectifier and it still is not charging.

Re: replaced rectifier and it still is not charging.

Vic..... I have always excelled in the electric/electronics area trouble shooting department but using the word "infinite" was simply a goof (happens when sick as a dog). I was speaking of using a analog (needle) ohm meter and receiving a near full scale reading similar to a dead short.

The "no reading" mention pertaining to having a ohm meter set to hign ohms and connected to either yellow stator lead should have been self explanaory to anyone with the slightest knowledge of an analog meter. No reading..... that needle doesn't move!

However, should my reply have resulted in total confusion that needed correcting in detail (more than once)..... my apologies. Next time, I'll list the exact readings requires as per the factory manual to avoid confusion.

Re: replaced rectifier and it still is not charging.

The question here was do you have 12 volts on the purple wire going to the volatage regulator when the the mtr is running ? As i said before, this is what turns the regulator on when the the mtr is running.

Re: replaced rectifier and it still is not charging.

Joe Reeves, no apologies needed for me. I new exactly what you were talking about when you posted it. Hope you feel better. By the way, I still have my Stevens AT-101 and still use it a lot. Sorry to say but it's the only one I trust.

The question was....

Does your new rectifier have a purple wire coming off it that connects to the engine wiring harness purple wire? If so, make sure there is 12V at the engine purple wire when the key is turned to ON and the engine not running.

and like I said it does have 12v when the key is in the on position. if that is the wrong way to check it then I will retest. I only did what i was asked.

Re: replaced rectifier and it still is not charging.

For the record....I think Joe Reeves is an excellent tech/troubleshooter as he has helped me many times as have many many others. I believe what makes this forum better than others is that everyone puts their heads together to help fellow boaters figure out our problems like the saying goes "Two heads are better than one". I do not think what Vic said was meant in a negative way and I am sure that the confusion was solely on my part. I like to think that this is not a competition to see who can help the most people but rather a collection of experienced boaters trying to help beginner boaters or any other person in need of help or advice.

I appreciate the help from everyone that has offer advice on this frustrating matter, and I pray that the new stator corrects both problems I am having although I know that is a long shot. Thanks again

Re: replaced rectifier and it still is not charging.

I'm interested to see how this turns out for you. I have the same issues, although I have as yet to put the R/R in. I too have 18VAC from the stator at idle but it climbs quickly to almost 60 when I lift the start lever and increase RPMS.

Please keep us posted!

Re: replaced rectifier and it still is not charging.

Stator arrived today, I will try to install tomorrow and post results. I pray this works!

Re: replaced rectifier and it still is not charging.

The power pack has nothing to do with the charging circuit.

The reason I was thinking it did was because I read this on the CDI website:

WARNING! This product is designed to be installed by a professional marine mechanic. CDI
Electronics cannot be held liable for injury or damage resulting from improper installation, abuse,
neglect or misuse of this product.
SERVICE NOTE: Discoloration of all the battery windings is an indication of a problem in the
rectifier/regulator. Discoloration of only one post of the battery windings indicates a problem in the
stator.
Installation
1. Remove the negative battery cable.
2. Remove the flywheel.
3. Disconnect the original stator wires.
4. Remove the original stator, saving the original bolts.
5. Install the new stator using the original bolts with a good thread-locker applied (CDI 989-3977 is
recommended) to the bolts and tightened to the factory torque specifications.
6. Connect the new stator to the power pack.
7. Connect the new stator to the regulator/rectifier (ignore any stripes on the rectifier as the new
stator does not require the Yellow wires to be connected to a particular rectifier wire).
8. Replace the flywheel according to the service manual.
9. Replace the battery cable.
Troubleshooting the stator
No fire at all:
1. Disconnect the kill wire and retest. If the ignition now has fire, check the kill circuit.
2. Check the resistance between the brown and brown/yellow wires. You should read approximately
500-700 ohms. DVA (peak voltage) should be 150v or more.
3. Check the resistance between the orange and orange/black wires. You should read approximately
95-105 ohms. DVA (peak voltage) should be 12v or more while connected to the power pack.
4. Inspect the flywheel outer and trigger magnets to see if they are loose or broken.
5. Disconnect the rectifier/regulator and retest. If the fire returns, replace the rectifier/regulator.
No fire on One Cylinder:
1. Swap the brown wire and brown/yellow wire and see if the problem moves. If it does, the stator is
likely bad.
2. Check the power pack and trigger.
High speed miss or weak hole shot:
1. Connect a DVA meter between the brown and brown/yellow wires in each set and do a running
test. AT NO TIME SHOULD THE VOLTAGE EXCEED 400v. If it does, the regulator circuit in the
power pack is bad. The voltage should show a smooth climb and stabilize, gradually falling off at
high RPM (above 5000). If you see a sudden drop in voltage right before the miss becomes
apparent, the problem is likely in the stator.
2. Disconnect the rectifier and retest. If the problem disappears, replace the rectifier and retest to
verify that the problem was in the rectifier.

Re: replaced rectifier and it still is not charging.

I think you will find that the section you high light in red refers to part of the circuitry within the power pack. Something you have no access to. It does not refer to the rectifier/regulator.

However your extract does advise disconnecting the rectifier/regulator because there is some possibility that a fault within it can affect the ignition.

If r poor running persists with the rectifier/regulator disconnected then you have to look else where for the cause of that problem.

Get the new stator fitted. Hopefully that will sort the charging problem out.

With luck it may sort out the misfiring problem but cross one bridge at a time.

Re: replaced rectifier and it still is not charging.

ok, picture #1 and #2 are the origonal stator picture #3 and #4 are the new stator (Part number on this part is 583410 This number supercedes to a newer number 763769) , they look nothing alike, should I install anyway it looks like it will fit and it is the right part number but looks totally different. also the last picture is of the inside of the flywheel, it looks like there is a little surface rust on the magnets, should I clean it up or is this normal?

Re: replaced rectifier and it still is not charging.

If its the right part number and it fits fit it now you have it.

Clean the rust off gently if you like.

Re: replaced rectifier and it still is not charging.

Ok, I replaced the rectifier and the stator and my engine still runs like crap and the charging system still is not working!!!!! What else controls/effects the charging system???? I did put another known working rectifier on and it still does not charge!! any other suggetions???

Re: replaced rectifier and it still is not charging.

Well for all the manual test procedures the easiest test for a rectifier is to disconnect the red rectifier lead from the terminal strip, start the motor and measure voltage to ground. If you get 12.* volts the rectifier is good. Period. Electrically you likely have a broken/corroded wire someplace. If all your components test out and you have good spark and compression, the only thing left is bad/corroded wiring. You'd be surprised at how bad it can make a motor run. Also check and clean ALL ground connections. Basic electrical maintenance.
Hope this helps.

Re: replaced rectifier and it still is not charging.

Cleaned ALL wire connections and looked for any loose or disconnected wires. The only wire not connected is the previously mentioned Purple wire that goes to the VRO. The motor is still not running right, and it still is not charging. I feel like i am missing somthing. There is only 2 other things that can be replaced, the Timer Base and the Power Pack can either of these effect the charging sytem?? I am at a total loss as to what else it could be. I still am not sure if the 2 problems are related or just a coincidence. The mis that the engine could still be a fuel issue but I have rebuilt the carbs 3 times with no change and I visualy looked at the reed valves and they appeared ok. any other suggetions???????

Re: replaced rectifier and it still is not charging.

Since your stator tests proved it to be OK, I am not surprised that a new one didn't fix it.

Where are you anyway? PM me with the answer if you want. I'm in Mims, FL.

Re: replaced rectifier and it still is not charging.

You want to trailer it up here? Three hrs and guaranteed fix. I do not charge for anything I do engine- wise. Free anytime.

Thank you, but unfortunatley at this time it is un-trailerable. It is a project I am working on so I am working on the trailer as well as the motor, but if I get it to a point where I can tow it and I am still having this issue, I would love to take you up on this offer. Thank you so much.

I'm out of suggestions, maybe a shorted timer base is taking down part of the stator charge? I hope when you get this sorted out you post the fix. I'm really interested in seeing what this problem is...
