John, An alternate to resistance is to check voltage in and out of the ballast resistor. If you get your neighbor over, have him give you some pointers on using the VOM. Voltage and resistance testing is a great method of troubleshooting problems. If you don't have a VOM, I suggest getting one. A basic one is around $20 plus you can use it on the car and even the house. |

Now I'm really cornfused.
I have the MSD coil and directions say to add a 0.8 ohm resister. I read up on the electronic ignition conversion kit and it says to use a 1.4 ohm ballast resister. |

The ignition tech said the MSD wouldn't work with there conversion so I guess I need to just go get a standard coil.

Hey All,
Need a pic of how the coil is mounted on engine 83 PCM. Actually the mount also. I checked my 79 but it is on the opposite side, manifolds don't look the same. Thanks |

Never mind the pic I made a mount.
Next question--- Where can I get the Alt.& RWP belt replacements? Shipping is twice as much as the belts, surely they can be bought at a parts place.... |

These are the Dayco numbers from my 80's vintage PCM 15400 (11A1015) and 15455 (11A1155). Don't know which one is which but maybe you can cross reference them to any belt at a parts store. If you can wait til sometime tomorrow I can uncover it and maybe see which belt goes to what and the alternator pulley diameter to see if your new one is the same size.

Here we go again with the dumb questions...
I ordered a set of Sierra Marine plug wires and didn't think about the distributor end. Anyhow I have to return and the customer service said all they have is non marine. Is there a difference in marine and standard plug wires? |

I am not aware of any Marine special plug wires. I always buy high quality wires.
Napa sells Powerpath, used to be made by Belden Wire. Very good wires. Standard ignition purchased Belden so a premium Standard Ignition set would be high quality also. These would offer long life, great spark transfer and limit any sparks emitting from the wires to a ground which could be very bad in a boat situation with a covered engine. |

The only marine thing I can think of is that with the marine exhausts in place the normal method of running the wires from the distributor over the valve covers to the plugs are blocked. PCM chose to use longer wires and running them down in front of the valve covers then up to the plugs. So a set for a car or truck might not be long enough. You could then make your own or just buy a set ready to plug and play. link

John, My concern was the same as Gary's with the set being too short but, per the comment in the listing, someone has used them by routing under the manifolds. |

Here is another non paint question
When I removed all the spark plug wires from engine forgot to mark (actually I did, but it faded-duh). Will they be the same as on my 79 351? |

If you're asking if the firing order is the same, it is but...............you need to determine which terminal on the cap is #1 by finding where the rotor is pointing when #1 cylinder is at top dead center on the compression stroke (you may have to rotate the body so that the rotor lines up with a terminal) and that will be the #1 plug wire , then you go Counter clockwise around the cap with the reverse rotation firing order 1 8 4 5 6 2 7 3 You'll need to check and adjust the timing after it's running. This is the short, not too wordy version |

I'll vote for key left on without the engine running.
If the points are closed and the key is on without the engine running you have a direct path to ground and the coil heats up. |

Pump is not hooked up, just running enough to make sure it will run when I put it in boat. |

You can also hook a water hose to the inlet. I hook mine into the transmission water cooler. Gonna set that up later today so I can check for water leaks.

Install a Timmy T, you can hook up a garden hose in seconds and fire it up safely.
Read up on the Timmy T on this forum. Tim Provided a good how to. |

Didn't understand how it could work but the video shows it all. I thought for a minute I had a engine running backwards
