Here are 4 different engine harness diagrams, complete with wire gauge and colors.
Two of them show points ignition w/1 wire and 3 wire alternators.
The other two show HEI ignition w/1 wire and 3 wire alternators.
If you're using an aftermarket ignition such as an MSD, be sure and follow their instructions for wiring the box to the distributor.
If you're using an MSD R2R distributor by itself:
Black = Ground
Red = Ignition Hot & (+) terminal of coil
Orange = Tach Signal & (-) terminal of coil
No ballast resistor required

i think you answered a question i was getting ready to ask, i have never run an alternator before and am installing a one wire type, i am not running an aux solenoid so the wire would just run to the solenoid on the starter, right??, sorry if this is a dumb question, but i have never run an alternator in my boat before
-
Yes, a one wire alternator conects to constant 12v. The battery cable on the starter solenoid is a good place. ;D

Yeah you can run it to the point where the positive battery cable connects to the back of the starter....
Or you can connect it direct to the + terminal of the battery if you want also.
However, honestly I highly recommend the aux solenoid for reasons mentioned in my article regarding aux solenoids.
-
So, Jet, where do you get the best deal on the aux solenoid? and is there nay particular size requirement?

Just go to any auto parts store and buy a solenoid for any Ford truck. Shouldn't be any more than about $20.

Thanks. I've got to put in an order with Summit anyway so I'll check them out.

hey these are sweet i need these diagrams but it wont save on my pc :banghead:
-
I haven't tried saving on my computer, but I did print one out and use it while going through some of the wiring ;D
-

you can do it, its just a little tricky.
right click on the image, select propertys. highlight and copy (ctrl + c) the address (url). paste it (ctrl + v) into your web browser address bar......now right click on the image and select 'save as...'
im not sure why it does that, i just havent had the time to look into it.
-
If you use a Ford solenoid I don't think you want to ground that second small connection, that one usually goes to the coil so it get's voltage while cranking and is hot while the solenoid is energized, the solenoid grounds through the bolts that hold it to the firewall. There are some solenoids, I usually see them in motorhome applications, that use that for completeing the circuit, but the standard Ford starter solenoid isn't one of them.

I got a rubber coated one

No they dont NEED one but it's cheaper to replace one of those $16 parts than a starter .

Thats right,beerjet! ;D Well kinda...isnt there's BUILT into the starter? ??? So when your solenoid goes out,as you said....you have to REPLACE THE STARTER! :mad: Hey 2sav...where's the common sense in that? ??? ::) :banghead: OH YEAH.....your a "chebby" guy!! They dont have any! LMFAO!
Jus kiddin' here chebby guy's.....dont get yer panties in a bunch! >:D

We have a thread for that, it's called Ford vs. Chevy. ;) Read through that thread and cry me a... I mean call me in the morning. :-* J/K

DESECRATING A CHEV BY RUNNING A FORD PART TO MAKE YOUR CHEV START :screwy:.... FOR THOSE OUT THERE WHO WOULD LIKE TO KNOW HOW TO WIRE A SOLENOID THE RIGHEIOUS WAY LIFT THE HOOD ON A FORD CAR OR TRUCK YOU WILL SEE THE POWER SIDE HAS THE BATTERY SIDE ON ONE SIDE AND OTHER SIDE IS THE STARTER SIDE SEPARATION OF POWER FORD HAS WIRED THERE CARS AND TRUCKS THIS WAY FOR OVER 60 YEARS. YOU CAN WIRE YOU STARTER WITH ONE CABLE GOING TO STARTER WITH JUMPER WIRE AT STARTER TO ENERGIZE STARTER NO POWER AT STARTER EXCEPT WHEN SOLENOID IS ENGAGED NO EXTRA WIRE RUNNING TO STARTER. MY CHEV IS WIRED LIKE A CHEV I DON'T DESECRATE A FORD PART TO MAKE MY CHEV START IN MY FLAT BOTTOM IT STARTS WITH ONE PUSH OF STARTER BUTTON.
I new that chev guys where wired strange :banghead: large print easy to read second time :screwy:
-
hes got a good point there on the chvy starter i hate havin to wirethe thing befor i put it in lol ford is1 wire and ya cant drop the nut couse its big enuf to hold and ifya doo drop it you can findit lol. For Out Runnin Dumbasses
-
Don,t worry Chevy boys...GM copied Ford and made one identical for their motorhome chasis. Put this up before but here is the wiring diagram...

lol I just burned up my new starter trying to get my damn engine to start, hehehe imma try again tomorrow. :-)

So im rewireing the boat today from the dash back and have a question. On the wireing block on the back of the motor there is a wire thats tagged alt. Why would that need to go to the dash? shouldn't that go to a constant 12v like off of the starter solenoid?

I have a push button soleniod and a billet mount that bolts to the back of the head for a bbc. I'm Not using it anymore. no room. make me an offer I cant refuse and its yours.
-
Anyone? Im trying to leave on thursday for the avi. and don't dont want it to not be charging.
-
where does it currently go to on the dash?
-
voltage meeter. I think. I have the diagram for that harness. I can check it out when I get home.
-
where does it currently go to on the dash?
It did go up to my amp meter. but when I made the new harness I did it for a volt meter. the alternator I believe Is a 3 wire but there is only 2 wires connected. one im guessing is the exciter wire because it goes to the ignition wire and the other is the main charge wire I guess and it just goes up to the wireing block and im guessing the 3rd (non used) would be the idiot light. So tonight I took the main wire and ran it to the starter solenoid and hoping thats correct we will know tomorow after my battery charges.
-
here are 2 diagrams that I'm using. they were the same as the stock harness for my 77 Southwind. It's a bbc. They made a few upgrades tho. I couldn't get the pics to come out good so the top 2 are for 1 diagram and the bottom 2 are for the second diagram.
-
If you guys want the ford ones I can post them too. same with the oldsmobile. Its the least I can do for all your help.

I have a patranx distributer with 6AL MSD wich is the best diagram ? ???
-
mike , i think on your app.......
the coil power will be the same "in" but it will go to the msd box first then out of msd to the coil and pertronix leads out of the dizzy.
-
hey found this site while lookin for a wire diag for my boat. what a big help, thanks a bunch. one more question, my starter does not have a solenoid on it where do i run the purple, and white wire? 3 wire alt points ing. thanks again mike
-
yeah , run the ford diagrams !
-
hey do you have a diag for a bbf without a solenoid? what do i do with the purple and white wire? you guys ever heard of haskel boats?
-
this should help

-
that diag shpwes a solenoid on the starter. what if i dont have a solenoid on my starter?
-
i think you just run the big red from the solenoid to the starter!
-
Sorry for lagging guys. Here they are. Hope this can help you guy's as much as it's helped me.
-
I put em on a pdf so you can blow them up or print them. The universal one is the harness most of us have under the dash and runs to the back of the boat. depending on what motor make you have, ford chevy or olds is the harness that goes in the back of the boat. This is 90% of the wiring that goes in a jet boat.
-
Hey guys I'm having a problem with my charging system as well. The alternator checks out good off the boat but it will not keep the boat running when you pull a battery cable, it immediatly shuts down. I have an AMC 360 with I beleive the 3 wire Alternator. Will one of these diagrams work for that application? I'm planning on tracing each wire back and testing the voltage on each. I did notice that the Gas tank switch is not working along with the gas gauge and engine temp. Will these gauges not being in working order make it so that the alternator wont charge the battery. Would this be an incomplete circut. Sorry I'm new to boats and could use a little better understanding of the electrical system.
Thanks...
-
well i screwed myself royally. i have been taking pics of EVERYTHING when taking it apart on my rebuild, but what i didnt expect is my harddrive to crash. so now i have zero reference for my wiring. which of these should i use for my setup. SBC
DIST. pertronix converted, but i plan on installing a msd box and blaster coil.
1-wire alt.
Gauges- mech oil press, water temp, tach and voltmeter.
Mech fuel
basically a bare bones setup.
-
Use the bbc diagram I posted 8)
-
Thanks bro
-
You will also need to look at the universal 20" on the same post. they go together.
-
romper stomper your the man!! ive had so many pple saying i cant do this cant do that... and im fucking tired of hearing it.. MY lil brother passed away horribly .. and i took his boat its all i have. i just pulled the motor cuz of a bad ujoint..and with the motor out i decided to redu everything thats bad to save me time and money later. And the elecrical is teh worse. wires faded and shorted and now with ur pics and ur time to help out those who enjoy what u do.. i say brav fuckin O!
