I talked to vince at skidim today, turns out the right ignition module was ordered, the other module comes with a bushing full of magnets that fit on the shaft under the rotor. The part that's ordered is lobe sensing and works with either the 8 lobe points cam or the prestolite electric upgraded 8 vane doo-hickey, nk magnet bushing needed, he also said that bushing can break open and drop the magnets, also expect around a 20 degree timing change since the new module is in a different location, setting idle and timing was on the list anyway. Yesterday i got the ram air installed, should move plenty of fresh air to that engine

Ahh, I know Palm Bay. One of my best mates lives there. I went to FL Tech. With that said, I might be doing the airline thing on Sun/Mon to start a trip Tues. If time allows was going to shoot to Palm Bay. Would love to see the boat. |

Keno thanks again, i can't think of better hands that points distributor is in. got your pm, yeah i told them 40 something year old engine screw down cap 2 screw module, but it looks like the wrong one is on the way, ill call tomorrow and get the part number you sent me ordered up. Should be a no problem return.

One stinkin' little wire.
Funny what you can accomplish with a phone call and a TRB wiring diagram  Good job Dan, now you'll have a spare Pertronix module, if the Prestolite module dies And..........I have another Prestolite points distributor for the "collection of parts that might come in handy to somebody sometime" since Dan didn't end up needing it for anything.

Big thanks to keno and everyone for the motivation and advice.
1 wire was wrong, and i couldn't see it. New fuel pump and petronix module are ordered, expecting them tuesday. I guess it's time to order the dual taper shaft and coupler. Just pouring gas in the carb teaser. https://youtu.be/dphiGyAi5Qo

I'm embarrased, and with humility I accept and will be the proud caretaker of this distributor and return it when the d.u.i. comes in. Funny, one of my cousins reasoned out to me earlier this evening what i immediately knew when the engine didn't fire up right away. "your in to deep to scrap the project now" that's what aggravates me. When i read your post it humbled and reminded me of later in life how i felt after hearing from my parents about christmas presents for my brother and i when we where little kids, how they really couldn't afford them and the self sacrifices they made in order to get them under the tree. Ill double check part #'s for the fuel pump and d.u.i., make the appropriate calls and place the orders I'll pm and call you tomorrow, around lunch o.k. or is there a better time. Thank You, Dan

Have i got a deal for you Dan.
I helped a friend of a friend of a friend or something like that put a new distributor in his boat today. When it was all over with, I was the proud owner of a Prestolite points distributor with a screwdown cap complete with a Reverse Rotation gear on it. If you think your module is dead, PM me your address and I'll ship it down to you with a ballast resistor and a coil and an extra set of new points. You should be able to get some spark with that setup to get the engine running while you wait on the DUI. If you're not sure of how to swap distributors, I'm sure some instructions can get provided to you How can you turn down a deal like that? |

Disconnected tach gra from pos side of coil, nothing
Multi meter to engine block ground and neg side of coil, it read 003 key run and key start. Connected tach gra to neg side of coil, nothing Multi meter again, same reading. Never thought to check coil, tomorrow is another day. Disconnected battery charged to full in under 30 minutes. Defineately no power after battery switch when turned off, radio is hot to dash feed, switch on ='s radio on, radio can only be turned off by battery switch. Fresh eyes tomorrow, i'll trace, confirm and multi meter from front to back. Weather is turning the corner, other boat is calling very loudly

The GR is for gear reduction like you said.
It'll turn the engine over faster than the old direct drive starter does though. It's a fast turning motor and the torque is increased through the gear reduction to the pinion gear The reduction ratio between the motor and the pinion is about 4.4 to 1 PS......I know it's a new tach, but leave it disconnected initially. The tach or it's associated wiring being grounded when it shouldn't be, will prevent spark and drive you out of your mind. |

A full charge on a resting 12V battery will be around 12.7-12.8V. If you only have 10V without a pretty decent load on it, you have a battery that is extremely undercharged or damaged.

I got the tach gray wire on coil positive, i see that is wrong based on the drawing, i will switch that and test the module following the steps you provided first thing in the morning.
Yes the battery is brand new interstate 24xd marine cranking bought less than a week ago when they made up my battery cables. It wasn't connected to the cables until the day i first tried to start the engine. if the gr in pmgr means gear reduction is that why it cranks slow even with a full charge ? Also i'll write down and list the wires in run start and charge from where they originate to their end point. Thanks for the continued support and advice |

If you had continuity like zero ohms everywhere to ground you'd be popping that main breaker pretty quickly.
The distributor is grounded through the body to the block like you said and the black wire when disconnected like you had it will not be grounded. When it's hooked to the coil negative and the engine is turning it will be grounded and ungrounded continually as the distributor turns. When it's grounded by the electronic module it's letting the coil charge and when ungrounded, it sends a spark to the terminal the rotor is pointed at. If it had points it would be the same as points closed charging the coil and points open you get a spark You could check this with your multimeter hooked to the coil negative and ground. If you have it on the 20 volt scale you should be able to watch it fluctuate between about 12 and zero as the engine turns over. A steady non fluctuating reading means the module is bad and not letting the coil charge and discharge. Is this a new 10 volt battery? I hope not You have the good representative TRB diagram that got your starter wiring straightened out, now make sure your wiring goes with the rest of the diagram. Don't forget, I'm always open to a phone call and we haven't quit yet

first off, the battery after being on the charger all day yesterday was reading 10 volts today, therefore i get 10 volts with key on run and with key on start all the way thru to the alternator.
the battery is on a switch and nothing is hot unless it's on, the switch was 100 percent turned off yesterday, i had to turn it on to test everything today. i have good continuity of ground all the way thru to the alternator. disconnect distributor purple from coil positive and black from coil negative and have no continuity of ground to the block or the housing on the black wire, the housing has continuity to the block. what i think is wrong is continuity is everywhere, choke coil and alternator purple wires to block, to ground, to itself across the board. Distributor tag reads FOJL 12100 CA 7808 BS 3J 27 i disconnected the battery completely and called it quits |

Alright, i got the multi meter wire and alligator clips in a bucket.
Slept in and it's a comparatibely cool and breezy day outside, i'll go see what it's got and to where. My buddys' in another state, another pair of eyes and a second brain would be great but i can't discount and certainly appreciate the motivation and advice i'm getting

I agree. I didn’t know anything about engines and multiple people on this site have taken time (many times…thanks guys for always answering my texts) to teach me. I still don’t know much but every time I get stumped I learn a little more. Keep it up…you are so close to the pay off and enjoyment. Agree with keno, get that friend of yours to drop by for a beer or six. Looking forward to seeing that SN on the water.

Don't give up on it, you're not far from finishing it. You may not think you're an "engine guy", but this is how you become one.

Go Dan! It will be such a tragedy to see you abandoning this so close to the finish line. Everything's looking so good, and it really does seem (even to my very inexperienced eye and intuition) that these last few gremlins should be simple to sort out compared to what has gone into the build so far.

I just closed up and walked in from round 2, the first time it wasn't pumping fuel, lost prime.
It sat on the charger all day it was low, i mean why shouldn't it be, it's brand new. The engine still seems like it's turning slow (by hand it's butter smooth). This time it had a good prime, the hose from the jerry can was whipping at the same tempo of pump lever, it pumps real good, right up the clear vinyl tube and sprays all over the engine so earlier when i said it was back ordered i jinxed myself. So 60 bucks for the marine replacement pump from summit and they dont know when it'll be back in stock. Won't buy the same part number i got from carter from a boat place for 200. I'll add up fiberglass materials and list the hull for that price. Thanks guys

All right heavy sleeper, this is no time to quit, you never have and you ain't starting now Take a few days off, then get back at things with the engine. When you get back at it, hook a temporary can directly to the fuel pump with some clear 3/8 tubing and you'll be able to see if it pumps. Do the jumper mentioned earlier to the coil to see if you get spark. And if you have spark, you can check/set the timing to be around 10 degrees BTDC while cranking the engine Get your buddy to stop in for a visit If you have spark and the pump works, prime it with a little gas down the carburetor primaries and hang on for some nice rumbling noises. Now it's time for everybody to jump in here and give Dan some encouragement, don't be bashful

Thanks keno, my buddy called and asked a list of questions, he said the same thing about checking voltage and checking cranking voltage to verify ignition just doesn't have 12 volts with key on run but not with key on start (said it will crank but never fire)
to continue he said it still doesnt have fuel, and dumping some down the carb probably didn't help, said it's dry and will take alot . Also mentioned 15-20 seconds of cranking getting fuel to the bowls and bowls are worth 14 ounces and wont deliver until full. I may look at the voltage and try again, might loosen the fuel line at the carb to verify pumping, but all day it's been brutal hot and i've had enough of it, yesterday was 7 hours of wiring that engine harness with plenty of breaks and water. Distributor is back ordered, mech fuel pump is back ordered, what else does it need and by the time it gets here and i get it running boating season will be just kicking off and i'll be too busy bedding and glassing the stern tube in. No, it'll make a great boat for someone, it just needs a complete drop in, or an engine guy. Fyi i unlocked the trailer tongue and i'm a heavy sleeper Edit in, it's probably a simple fix and i appreciate you not giving up, nothing has ever beat me and i've never quit, normally i would see this as a challenge, think how dare you and go to no ends beating it and winning
