1964 90hp Johnson Meteor chargeing question ATTN R.Johnson

[roscottjr]

I have another post concerning the chargeing system on this engine. I have been trying to figure out why it is not chargeing. Nothing I have tried has fixed the problem whatever it may be. So far everything has tested good with the exception of the items I have not tested due to not knowing how to test them. I have just recently found a terminal on the bottom of the external box that houses the starter solenoid, regulator and diodes and such. There is no chargeing power going to the battery which I have confirmed with the engine running. However, I have just found that this terminal on the bottom of this box does in deed have an output voltage when the engine is running and it increases with the rpms of the engine. Should there be a wire going from this terminal straight to the battery or should it go to some other type of equipment? I plan on installing only 1 battery in this boat but I just need to know where this terminal should be connected. Here is a pic of the box. You can see the terminal on the left side of the box just to the right of the engine harness coming out of the box. About 2 inches or so from the left side.<br /><br />Thanks<br />Robert<br /><br />

I'm certainly no expert on this setup for the V-4s, but I do know about it a little for the 40hp engines. This is the generator that runs off the flywheel with a belt right?<br /><br />What's the other end of that wire hooked to? With the 40hp engines they ran a separate "charge" wire so you could run it through an ammeter and monitor the charge to the battery. The wire came off the "Batt" terminal on the regulator, via a 20 amp fuse.

No this engine has a stator mounted under the flywheel. Yes this terminal has a 20 amp fuse inside the box in the pic. I f I reading you right, all I have to do is run a wire from this terminal to my battery and my battery will get charged while the engine is running. Am I correct?<br /><br />Robert

Ok, well this is getting really far from what I'm familiar with so please excuse me if I'm wrong. <br /><br />If it's wired like the 40hp engines, that wire coming off the 20 amp terminal is connected to the positive terminal on the battery. This connection is normally made at the keyswitch. The reason they run the extra wire is so it can first go through a dash mounted ammeter if you wish.<br /><br />If I were you, I would fire off an email to Iboats member Droll:<br /> http://www.drolsum.net/johnson/index.html <br />He understands that charging system far better than I. It would probably be a good idea to provide a link back to this thread.<br /><br />I hope this helps!

Thanks. I sent him an email. Hopefully he can tell me if this wire must go to the key switch and which terminal and then to the battery or if it can go straight to the battery. I looked at the pics of his engine. Looks like he may have the same one as I do so maybe he will have all the information I need.<br /><br />Robert

Mail recived and replyid to .<br /><br />What voltage do you get on this terminal when the engine is running ??, normaly the charging voltage is connected tru a 60A fuse to the batteri .<br /><br />If the fuse is blown, the regulator will not adjust the charging voltage correct .<br /><br />Arne Kjetil

Posted some more pics. 1st pic is the external box showing the accesory terminal.2nd pic shows the 60 amp fuse which appears good and also tested good, large circl is brown wire going to the switch and small circle is wire going to Accesory terminal through 20 amp fuse.3rd pic shows the switch and the wires I need to hook up. The large brown wire coming off the 60 amp fuse in pic 2 is not hooked up and circled in pic 3. Pic 4 shows back of switch with switch letters marked in red, pic is labeled wrong, B is correct S and I are switched, S has white wire, I has red wire and white with red stripe wire, B has green wire and red for power to shifter. I believe that is what the red wire on terminal B is for. These pics and also pics of the boat can also be found at:<br /><br />www.shareaproject.com/pages/projectThumbs,p,241,00.html<br /><br />Thanks<br />Robert

Does anyone know if the chargeing diodes are still made for this engine? Aftermarket maybe ? If so does anyone know the part number and where I can find them? If they are not made, what would be my alternative if I need to replace the voltage regulators and chargeing diodes? I believe the chargeing diodes are also called rectifiers.

Don't know if it's available from the manufacturer , but there is several other diodes that's usable .
I replaced all diodes with this rectifier

Just connect the yellow wires from the stator to the AC input pins, run a wire from the (-) pin to ground and a wire from the (+) pin straight to the battery .

This rectifier is rated for 35A ( max charging is 20A ) and is used is stereo amps, power supplys +++ ( got 2 in my HIFI power amp ) .
I have mounted it to the side of the powerhead, just keep it dry ( water + electricity = corrosion)

I have an old car amp and pc power supply but dont think it has one of those. What brand and model did you pull that from? By any chance would you have another?

Re: 1964 90hp Johnson Meteor chargeing question ATTN R.Johnson

Droll. I almost forgot, what do you think about the brown wire in the pics above? I think I have figured out where all the wires go and I see no reason they wouldnt work but just want to make sure before I start the engine and take a chance on burning something up.

Re: 1964 90hp Johnson Meteor chargeing question ATTN R.Johnson

Droll, I found that very same rectifier for under $5. What do I do about the red and blue wires coming from the stator?
