1967 33 Hp Johnson Wiring Dilemma

[rfevans]

I have a 67 Johnson 33 Hp that I picked up recently trying to ready to install on my fishing boat. I have just spent a week rounding up linkage parts to try to put this thing back original all the carb linkage was gone solenoid choke linkage ect. The P.O. had removed it all and had all the linkage wired together with everything from string to tie wire lol. Another great member here helped me get that all back straight in a previous thread. (Thanks) What I have done so far on this Check compression which is great, Cleaned Carb with new kit and installed and I have great spark. In the process of getting that done I checked my wiring out the P.O. had this wired up to remote push button starter but no kill switch I guess he just choked it dead or ran it out of fuel. I'm still in the process of tracing this mess out. I did find that 5 or 6 wires between the engine and the control box had cut and removed. Here's where the questions start. This engine has the generator on it and those wires are some of the ones missing in the harness. I have a manual and a wiring diagram for a 68 so my plan is to make a new harness all together. I don't know much about these generators on the old outboard and Im not finding much out about it in my manual. I have a feeling there is a reason the wires have been cut and removed. All the hardware is here Generator, Regulator except for the wiring. With that I am leaving it you guys what direction would you guys go from here and how do you trouble shoot the charging on this old 33 and is the generator even worth the effort. Any and all advice greatly appreciated. Thanks in advance Randy

What's wrong with the wiring diagram F_R posted in your other thread? IF he cannot do any better, then I doubt anybody can!

Nothing is wrong with that diagram that is the one I am building the harness from. I also have one in my 68 manual but is not as good as the one I got From F_R. I guess I was not clear about what I was needing or wondering sorry about that. I suspect there is something wrong with the charging system and for one I don't know how to trouble shoot it. I could make up a make shift harness pretty quick. Its in a tub and in good running condition now. Theres really just two items to check Generator and the Voltage Reg. F_R posted excellent info for me in the other thread. Looking around I have not been able to find a replacement V.R. I could have the Gen rebuilt here locally if needed Or I could remove all of it from the engine completely trying to figure out which way to go and what others would do. Thanks for the reply.

The generators were mostly used on engines with electric shift, since you don't want a dead battery when your shifting mechanism is dependent on good battery power. With a manual shift motor, it isn't essential to have a generator. I use a small solar charger on my battery on my pontoon boat, and I don't have to manually charge the battery all summer long. Even without a solar charger, if the battery is just being used to start the engine, a manual charge every 2-3 weeks will probably suffice.

Thanks Lindy46 thats a slick looking ride you have there. Reminds me of the one I have in the back yrd stripped and waiting on spring time so I can paint. I think I will probably go ahead build a harness for it for now. After looking at the diagram I am missing a piece of the puzzle. I have no ammeter in which I dont know which one to buy for it anyway. I do have a couple of old cub cadet ammeter's for the old starter generators for there application which is another hobby of mine that might work to get by. Will a regular automotive ammeter work? Anyway for now I'll make my new harness equipped for the generator and leave it unhooked a figure that out after I her on the boat. I would like to get it charging we do a lot of night cat fishing so charging the battery would be a good thing. Thanks again.

Any 10 Amp ammeter will work

Re: 1967 33 Hp Johnson Wiring Dilemma

Voltage regulator is part number 377001, superseded by 381538. It is about $100 from an Evinrude dealer. It IS NOT a car regulator.!!! It is a 3-unit regulator set for 10 Amps. I know of no car that only has a 10 amp charging system. Attempting to charge at more than 10A may burn up the armature in the generator. There once was a Harley Davidson motorcycle with a similar regulator. They have pretty much been replaced with a solid state unit. That is another possible solution for you if you know what you are doing.

There are also 2-unit regulators for tractors. They do not have a current regulator, so you are back to the uncontrolled amperage problem. (So don't use one).

The generator itself is simple to test.

Thanks whaler see what I can round up

Re: 1967 33 Hp Johnson Wiring Dilemma

F_R I am way to green to try to put anything other than original. My electrical skills are not that great as far as knowing what Im doing on this system. So for now just building a new wiring harness correctly and leave it unhooked till I round up a ammeter get the thing on the boat and then trouble shoot it. Trouble shooting this is my weak spot and also finding the right ammeter. Thanks F_R

Re: 1967 33 Hp Johnson Wiring Dilemma

An ammeter is an ammeter. All that is required is that it is DC Amps and at least 10 amps +/- (0 in center of scale, shows charge one way and discharge the other way). Any universal automotive one will work in that respect. However they usually read up to 60 amps, no problem except your puny little 10 amps or less will barely move the needle. Original ones read 15 or 20 amps max.

Re: 1967 33 Hp Johnson Wiring Dilemma

I didn't think they made an electric shift 33? If it's a manual shift I would remove the generator and all the wiring and also get a solar panel. I use one on my pontoon boat (1' square) and I never charge the battery for the entire season.

Re: 1967 33 Hp Johnson Wiring Dilemma

Im big on the solar chargers too. Canadian Tire had some smaller 6"x12" on sale last summer for like 10 bucks. I bought a few, and as mentioned, keeps everything topped up for the summer.

Frank I believe I used a solid state 10 amp regulator from a Harley Sportster, late 60s on a job for a friend. I believe you had found the part number for me as well back in the summer. It was 381-309. Wiring it wasnt that bad. Mounting it required a little modification of course.

So as long as you dont mind it not being 100% original......the Harley regulator is half the price. If you decide to go that route, I have Franks wiring instructions for it.
