6. Please do not post to threads that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any thread that remains inactive for that long should be considered "dead". It is especially confusing when there is an entirely new question posted to an old thread.

7. Posting at the end of any thread is considered to be hijacking the original posters thread which in turn subjects the thread to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive thread asking you not to reply to old threads. The Red banner will read: Please note this thread has been inactive for 90 days. For the best results, please start a new thread.

  • Wiring help for 1963 28 HP Johnson

    Hi,

    I picked up 14' 1970 sears boat and a 1963 johnson 28 hp outboard for $300 and now I'm trying to get the motor up and running. I'm going to get a set of johnson controls, probably the shipmaster ones. There are 4 wires coming out of the engine (Other that the large battery + and -): red, white, black and green. I believe the red is choke. ANy ideas on what the other 3 are? Do I need a solenoid? Any other pointers on this motor would be greatly appreciated.

    Thanks

    Forgot to mention it's a RX-11A if that helps

      There are 4 wires coming out of the engine (Other that the large battery + and -): red, white, black and green.

      The wires mentioned sound like the key switch wires. I linked a schematic for you. Also, you will need a solenoid. I included a link to a pic. Btw, I'm working on a RX-10. Just waiting til the ice melts to test it out.

            yep, that's it.
            Are you doing a remote setup?

              yeah it will be a remote setup. I just need the solenoid right? Do you know what part number it would be?

                No, sorry can't help you there.

                edit: Hopefully one of the experts will chime in with a part number for you. You may be able to get one here on iBoats.

                    I have a manual for a 1968 Johnson 33hp motor, which is essentially the same motor as yours. While I have to caution that the wiring may be different than yours, it probably isn't.

                    The short answer is that the white wire (16 ga.) runs between the start terminal on the starter solenoid and the "S" terminal on the key switch, the black wire (18 ga.) runs between the center terminal on the vacuum cutout switch and one of the "M" terminals (the one between the "S" & "Bat terminals) on the key switch, and the green wire (12 ga.) runs between the hot side (red) of the starter solenoid and the "Bat" terminal on the key switch.

                    On my diagram, however, the choke circuit has a red/white wire (16 ga.) running from the choke switch to the choke solenoid. The choke switch is fed by a solid red wire (16 ga.) from the "A" terminal on the key switch.

                    Also, there should be a black/white wire (18 ga.) running from the other "M" terminal to the black wire (18 ga.) that runs between the coil lead assembly and the center post on the vacuum cutout. That wire is spliced to the black wire with a wire connector.

                    You didn't mention a generator and voltage regulator, but if the motor has/had them, there will be a brown wire (12 ga.) that runs from the "Bat" terminal on the voltage regulator to the "Gen" side of the ammeter. The "Bat" side of the ammeter will have another green wire (10 ga.) that runs back to the "Bat" terminal on the key switch. Notice that this green wire is 10 ga. instead of 12 ga., as was the case with the first one.

                    I have a couple of these motors, but haven't looked at them in a dog's age, so I am providing this info purely from the wiring diagram.

                      the chart with solenoid part numbers does not cover 1963, is it the same for all 28 hp models?

                            ok, I'm trying to wire it up on the stand so I can work on it. I have the starter solenoid wired up and that works . I know the red wire coming out of the engine is positive for the choke solenoid and that works. That leaves the following wires.

                            White- I think this should get positive to go to vacuum cutout and safety switch

                            2 black wires- one goes to the vacuum cutout the other to the kill switch. Are these both grounds?

                            im putting switches on the wires so I can test it on the stand but something is wrong because I'm smoking the switch. PLEASE HELP!

                              got the white wire figured out. Still working on the 2 black wires. I figured that had to be the + for the ignition so I hooked it to battery positive. Using a spark tester I noticed that even when the motor wasn't cranking over there was constant power going through the plug wires. This made me think that maybe something was wrong with the points, maybe they were grounded out. Then I disconnected the spark plug wire and smoke came from the points I'm really stumped here. I went ahead and ordered the points tune-up kit but still cant figure out how to get this thing running
