replaced rectifier and it still is not charging.

Re: replaced rectifier and it still is not charging.

Trouble shooting the fuel, ignition, and charging system on that engine isn't that difficult. Something here apparently is left being unsaid, overlooked. The advice that's been given should have had that engine running great.

I agree, I am sure it is something I am doing on my part that is keeping this from getting resolved.

Re: replaced rectifier and it still is not charging.

Just wondering if anything else could effect the voltage to the coils (i.e. timing) because like I mentioned before, when I try to check the timing, the timing light does not work but it works on my car (I have tried 2 different timing lights)(and yes I do know how to use a timing light).

The reason I ask is because I have 2 different power packs and 8 coils and no matter what combination of parts I use, I have the same voltage. The only thing I have not changed/replaced is the flywheel and the timer base.

Also, someone mentioned that I was thinking that my rectifier "can not be bad because it?s new" or something like that. I KNOW the rectifier is bad, I just want to make sure why it went bad right away before I put another one on there.

I am sure there must be something simple that I am not seeing because no matter what I do I get the same symptoms and the same test result even though I am using different parts.

Also, can anyone tell me the common symptoms that occur when a timer base is bad. Mine teast ok, but I was told that sometimes they test ok but still cause problems.

Thanks again!

Well, I am done with this. Take time to post, follow this guy's problem...and I SWEAR he doesn't even read the posts. Or if he reads them, he is not comprehending them.

Poker...go back and READ my post on 7-17 at 10:40am. Try to comprehend it.

It was suggested to me that this is a HOAX post. Maybe so, maybe so.

If not..sincerest good luck in fixing this. You will need it.

Re: replaced rectifier and it still is not charging.

I've been following it too, from the beginning. The stator tested fine back 30 posts ago, replaced and same thing. The charging portion of the engine is relatively simple as compared to the rest of the motor. Stator to produce AC current, rectifier/regulator converts and regulates- the wiring harness connects it all together. Can only be one of the 3, stator is good so either the wiring is bad somewhere or the regulator/rectifier is fried or defective.

I promise this is NOT a "HOAX" post. I do not know why anyone would want to even do such a thing.

My comment about the rectifier being bad was not ment to say you were wrong in what you were saying, I was agreeing with you in the fact that I do think the rectifier is bad, I just do not want to blow another one so I am trying to figure out if it is in the wiring or something I did (most likely the latter). when I installed it I had the battery disconnected and I did not reconnect it until I was done. The fact that the rectifier di not work for even a second, is what has me concerned that if I put another one on it will do the same thing.

I apologize if anything I said offended you, it was not my intention. I apprecieate all the help and advice you and everyone else has provided. I am hoping when I get the harness off I will find somthing obvious, but like I mentioned before, my wife just went into the hospital so I will not have much time in the next couple weeks to work on this issue.

Thanks again, and sorry for the confusion.

Agreed, I will post an update when I get the harness off. I know the rectifier is bad, but it blew instantly and I am trying to find out why before I put another new one on.

Thanks!

You have to do the voltage test only when the moon is full.

Re: replaced rectifier and it still is not charging.

You figured it out yoursefl Pokertrampp #147. But you still want to throw money at that motor. Most people in this forum wind up figuring things out themselves anyway. Watch your spark tester while moving, gently tugging, bend & wiggling the wires. Watch for areas where they touch something hot or where they bend back & forth.

Re: replaced rectifier and it still is not charging.

I have a couple of questions for you.When you are working on this engine are you testing it in a body of water (lake pond river etc. etc.) Do you have a "workable" tach in the boat. Why the tach question, with our motor 140hp.it seems that any time it starts to "act" up its time to replace the rectifier no questions asked! Now where you are testing your repairs, our engine had a "miss" problem like yours when it ran for a continuous long time (skiing),we found that if we took the "hood" to let the engine cool down the engine would run perfectly until it would become hot. someone iboats explained to me that the power pack was starting to show its age (getting hot) replaced
the pack problem solved!

1) No, the boat is not in the water (on muffs).
2) No, the tach is not working (NEW Rectifier immediately went bad).
3) Engine runs bad hot or cold.
4) Power Pack and Stator have been replaced. (going on 3rd rectifier)

Re: replaced rectifier and it still is not charging.

Do you intend to take up Daselbee or Clanton on their offer?

Yes, I think Daswlbee may be a little far, but if his offer is still availble I may take him up on it. I think Clanton will be alot closer though, but I hope by the time he comes down I will have this issue resolved. As I mentioned before, right now I dont have the time to really do anything with my wife in the hospital. When things get back to normal, I am going to remove the harness and look for anything obvious, and hopefully this will be over.

If I do end up getting one of these guys to help I hope they will walk up to and and find an obvious problem that I just overlooked or mis-read a test reading (which is most likely the case). It will be a little embarrasing but at least the problem would be fixed.

Thanks again!

Re: replaced rectifier and it still is not charging.

Rectifiers failing like this are a puzzle.

Not got the battery connected wrong way round ?

I have double checked to make sure that is not the case also checked to make sure it wasnt reverse charged. with that said, the boat has a battery switch installed, could this be causing the regulator to fail or are these pretty fool proof, I did not install it, it was already installed on the boat when I bought it, but it is very well hidden and hard to get to, so I was thinking maybe there might be some type of issue with that...

Re: replaced rectifier and it still is not charging.

If there's corrosion in the switch even partially leaking to ground or arcing causing the system to draw more current, that could be a problem. I would try to eliminate the switch, just go from battery to motor.

When you say "eliminate" do you mean permanently, or just for testing purposes?

If I have time tonight when I get home from the hospital, I will try to see what?s going on.


Thanks again!

Re: replaced rectifier and it still is not charging.

I'm assuming you mean battery switch in the sense that there's a switch terminal block or something that allows you to hook up 2 or more batteries and switch between them. Not the key switch. Just verifying for my own clarity. If so, yes, go right from the battery to the starter solenoid and motor ground with the battery, bypassing the battery switch. For testing purposes at this point.

Yes, I was referring to the Battery switch.

The switch seemed ok but I disconnected it anyway. so far there is no difference.

I disconnected the big plug and I checked the pins with battery on (engine not running) and I have a short to ground to 5 of the pins, is this normal, I figured at least 1 would be like that and maybe 1 or 2 more for temp gauge, but 5? is this normal or is it indicating my problem is in the harness or something is wired wrong? There is nothing visible to indicate what the pins go to or come from. it looks like the external harness is new from P.O. but he internal harness is old if not original to the motor.

Re: replaced rectifier and it still is not charging.

looking at my clymer pdf service manual (I know, not oem, but...) it shows 1 main ground connection coming out of the plug. 5 to ground, you'd have to get the wire colors but I can't see 5 to ground being good, there's only 8 wires in the connector. This would definitely be killing rectifiers, if not more on your motor. I'll try to post the diagram in a minute here...

Ok, this is for a 1988-1989 120hp Johnson...Connector is at bottom left of diagram. I only see 1 black wire leaving the connector that is a dedicated ground by the wiring diagram.

Not saying yours is a Hoax, but just pointing out i think it does happen on here every few years, just so some weirdo can laugh at us all scratching our heads. If you dont have any thing to do for an hour or so you need to read this post, that im linking to. It is hillarious, the guy talks about skiing behind a 4 cy motor with only one side fireing and the other side with no plugs??
