Yes, funny since you seem to have the same problem I have at times. I think the acronym is "ADD"!

Chris, Note that the solution is deleting the fuse. Go back in this thread to the link to the complete thread regarding removing the fuse. |

Gary, Thanks. Interesting thread! Mark sure is our guy to investigate and come up with the solution. PCM or CC must have had their wiz "EE" on the original wiring/fusing!

Has anyone heard why the fuse is blowing? There's always a reason for blown fuses. What other overcurrent protection is there for the EEC after the fuse is eliminated?

Great that you found the fix
 I added this one to the: http://www.correctcraftfan.com/forum/forum_posts.asp?TID=25584&PN=1&title=poor-mans-gt40-diagnosis thread. I put the fix in the row in the spreadsheet next to: Fused Line in Batt Box For EEC Power |

Jason, I sure hold you inform that "mechanic" you took it to and couldn't figure out the problem! BTW, did he work out of his back yard?

GT-40s have a 160. Carb'd usually 143.
Great to see your problem solved so quickly! Go Lewy

problem solved!!!!!!!! it was the fuse. put a new one in to hold us over till after memorial day and then i will do the fuse delete as shown above!
you guys are amazing. Big thanks to Lewy! On more question though.... what is the normal running temp of a GT40? I have replaced all the sending units and i think i have a bad gauge. I hooked up a manual gauge on top of the manifold and it seems to be holding a steady 160 ish..... Impeller is new so it is not that. |

Fuses should always ohm out at "0" or near... they are a current path and should provide no resistance if they are good. if they are bad (as you have discovered) they are open and provide infinite resistance. I believe the retrofit is to remove the fuse, (connect the two sides of the fuse wire, removing the fusing path. they do make blade style fuses as well that have a waterproof enclosure.

just tested the fuse.... looks to be dead. multimeter is not moving at all. tested three fuses that i know are brand new and good and the meter moves to zero.
i think you guys might be right.... this fuse could be bad..... I will repost tomorrow afternoon when i get off work at 1. thanks for all the help guys! |

It's going to be soon that you'll see more problems like these,the newest Ford being something like 14 years old already. Pretty soon even the dealers won't have anyone who knows them either. Mark will be in demand with what he has done with them

You are correct. Mine is an all black wire,when I first got the boat,I repaired all the battery terminal ends. I hooked that black wire to the - side of the battery and no start. Quinner comes over and says why does a wire on the - side have a fuse? Well duh! Looking at a good fuse on the ohm scale it should read the same as when you touch both leads together. If the fuse is blown it would read the same as if the leads do not touch. |

I think that's an in-line fuse holder. Just pop it open and see if it's blown or not.

i just read that thread lewy posted and it looks like that fuse would keep power from making it to the eec which im guessing would keep the pumps from priming and prevent the coil from sending spark to the dist.
