| just finished restoring a 1989 bfn 351. before the restore all the acc/bilge/lights/horn/etc worked. Now the only switch that works is the ignition. The first couple of times after the restore that I took it on the water I was able to kill it with the key. Now I can only kill it with the ign switch. Any ideas? |

Sounds like a loose ground wire. |

I struggled with corrosion under the crimped terminals on my 1984. Soldering them up got me about 5-7 years, then the wires started breaking at the end of the solder joint. I had big voltage drops at the 8 pin connectors used on my boat as well, I measured as low as 9.4 volts at the ignition (with no ballast resistor due to my electronic conversion). Rewiring the whole thing point to point without connectors solved the whole problem. Pulling the engine now requires a little more work. |

Do you have a link to your restore thread? It sounds like you potentially have a couple things going on. The red wire, or constant positive comes from the engine to the dash, as part of the engine harness. It goes to the input side of the push button breaker Then comes from the output side of the breaker, to input side of the key, horn switch, bilge switch, nav switch etc. Usually in a daisy chain format. Meaning that the wire does jumps from the input side of one switch to the input side of the next, etc. As far as your switches, something got broken or was not connected. Remember, these switches aren't grounded, they just switch positive to the accessory. The other side of the accessory is then grounded. As far as the key, either the key itself is defective, or you have constant positive going to the output side of the key. Or you have constant hot positive (Red) going directly to ignition Switched Positive (Purple) somewhere along the line. |

| I am not an electrician so don't laugh. I do believe I have a ground issue. I think it may be an issue with the ground strip under the dash. If I touch the horn ground to large gauge ground on strip it works. If I touch blower ground to large gauge wire it works. Does anybody have a pic of how the wires are supposed to be oriented on strip. There is 6 slots and 1 is open on mine. There are metal bridges between all of the slots connecting them except for the large gauge wire is separate (no metal bridge). Thanks . |

I'm going to say that's probably your issue. Somone probably used a Terminal Block, which is meant to separate the indiviudal circuits, in place of a Bus Bar, which is Meant to unify everything connected to it. The only question is whether or not there are actually separate functions going to that strip/bar (no pun intended). If everything is for ground, they should all be tied together. Pics would help.

Left one= Stereo, Middle I'm not sure, blower maybe? The right one is the horn. Yeah, the ignition breaker supplies the key. But, it has the advantage of supplying other switches like the blower and bilge without the key being in. |

| Could somebody help me out by uploading a picture of their ground strip under the dash from a 89 bfn or similar all hooked up. I cant tell if my strip is original or if certain grounds should be together or not. thanks. I appreciate all of the help so far. thanks. |

i can't believe Brian didn't link his own http://correctcraftfan.com/forum/forum_posts.asp?TID=21901&PN=2&title=added-new-dash-ground-to-93-with-pics" rel="nofollow - thread ! lol. He has pics of his bus bar. I show a diagram of my terminal strip. I wanted to just get it done and none of the local stores had a bar, that's why i used the strip, but had to jump each part of the strip. My original '89 SpN wiring was just pig tailed all together. I can't say for certain, but it would make sense that the original wiring in the BFN would have been the same. The middle icon...is that possibly a heater? |

Original or not, all grounds are common. Together or not, they all go to the same place. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |
