Should you carry 2 sets? what if one is bad out of the box?

So............let's see, if you have points, you should carry a spare set and a condenser too since you never know what might happen with these hi tech mechanical things
Imagine that |

Plenty of parts in close proximity where the 2 sides of the points could be touching (besides the pivot). Either way, if the 2 sides aren’t isolated then they’re junk.

No clue but that is what I was assuming. He was getting continuity on both sides of the points while they were open. That's about the only way it could be jumping across. I had him disconnect the condenser from the points plate to take a ground via that out of the equation.
(I was diagnosing by phone) |

Yes Zach, tell us more. Is the insulating pivot point bushing worn through? Can't tell from the picture. |

I guess Zach will have to explain how they were conducting thru the center post/pivot point |

Guess we need a pic of the old points. Tomorrow I’ll be back a computer to post one. And I did lightly sand them with 220 before phoning a friend.

I'll second that Ha And............I won't even ask how ugly those points would have to be to conduct thru the center pivot. |

Ha, I believe the points Mallory distributors are set up with the pass through stud and insulators.

Yes, a little testing goes a long way and you avoid just throwing parts at a unconfirmed problem. I remember a Prestolite that was giving me problems. They use a machine screw through the side of the distributor body that the point set and the - wire are connected to. The screw has insulating washers and a bushing to keep the screw from grounding to the body. The bushing was out of position so the coil was constantly grounded. The VOM told the truth!!! |

He did Pete. His points set had started transferring electricity via the pivot point so no amount of cleaning would fix that issue.
Now David has a really nice understanding of how a points ignition system operates. |

David,
Did you try to clean up the point contact faces with abrasive paper or a file? Dave didn't need to go to 4 auto parts stores after he cleaned them up! If it happens again, get the VOM out and Ohm out the points. You will want to disconnect the - wire off the coil, rotate the engine so the point set is closed and then Ohm between the wire off the coil and ground. |

Thanks for the help. Made the rounds to 4 auto parts stores yesterday. Oreilly was the winner with points. Came back to lake and popped them in and a new condenser. Set gap and got lucky on first try. Started up and ran like a top yesterday afternoon. Fingers crossed this morning. Will check dwell when I have a meter. Gaped to .017 with a feeler. Thanks also to Zach and Tim for some troubleshooting. Skied Larry, Joel and myself yesterday and got up to ~45 with 2 in the boat.

Definitely sounds similar to my problem, and refreshing the surface on my points and resetting dwell was the cure.
One final item on my boat ..... I found that it was starting hard on cold starts, particularly after damp weather. The plug wires were old and looking closer could see they were cracked in places, I replaced them and instantly had stronger spark and now cold starts are fine. |

Napa might have something,mine in Florida did. But it took two tries,first time I didn't even make it out of the canal before the condenser failed. 2nd time was the charm and is still in there.

Here's a link to an old post with a bunch of part numbers for the points from different manufacturers. They'll be able to cross reference something and probably not have anything in stock. A NAPA might have something in stock.............maybe A little sandpaper might do wonders though. And if you keep reading you'll see some good ole' fashioned bickering about condensers too link |

Having a similar issue. Trouble shot it with Zach on the phone yesterday. Thinks the points are constantly grounding out. There is nice gap and the boat ran fine all summer. Was also wet in there. Dried it out well. And tried again this morning and nothing. I have gas in the carb. Anyone know what points my distributor would have. Heading to advance auto in a bit.

It's been years since I ran it, but we were discussing and can't remember how many. Maybe 4? I've meant to get it out but in truth one of the other boats almost always makes more sense, so it sits. I was really happy to be out in it yesterday, the thing still runs extremely well, sounds great.
While of course I'd much prefer to turn the key and have it start right up, it was fun to be in the yard working on it, my siblings helped out a bit, then our neighbor came over to offer his 2 cents. His dad bought it new and I bought it from him around 1980, so everyone feels a bit connected to the boat and loves to see it still running strong. |

Dave,
I'm glad you found the problem and thanks for getting back with the results. Yes, it's always great to hear back. How long had the engine been sitting for the points to corrode up? I've had them go for years of layups without issues and then sometimes one winter layup will do it. |

Just a few more details, because I like to give feedback when I get advice and was typing on my phone earlier. Pete, I did check resistance across the points before I did anything, they were not conducting at all. Cleaned them up gently, had no resistance on the meter but after some more struggles ended up cleaning them a bit more aggressively. So that was the core problem. Dwell was around 22-25 degrees, adjusted it to 30. By the time I was again trying to start the engine had flooded, plugs were wet, I pulled all of them, dried them off, cleaned up the electrodes, spun the engine with the starter to air out the cylinders a bit, left things open for another half hour, then reinstalled plugs and it fired right up. On the coil - I guess I don't know for sure the old one was bad, but spark visually looked stronger with the new one so I went with it. When I tested the old coil last night I had around 1 1/2 ohms on the primary circuit and I think just under 6,000 ohms on the secondary. For $39 for the new coil I figured why think about it for very long.

Tom, I chuckled when I read that! Just shows that I jinxed myself when I said that on the other thread. Funny thing is it was suggested I just bring my '98 to the lake but I don't like to give up so wanted to have the '63 running. |

I hope you were thinking about Pete while you were playing with your points
If you have some prehistoric points like Pete, ( that's the points I'm talking about, not Pete} you're probably just as well off with the cleaning job as compared to a new set that aren't usually very good these days like Gary mentioned. |

Success! And, a fun afternoon in the boat. A combination of things, you guys were right on the points needing to be sanded, also had to adjust dwell, dried out plugs and cleaned them up, I changed out the coil and appeared to have a stronger spark with the new one. I'll put new points in next week and check timing, just wanted to get on the water today.
Thank you! |
