How Do I Test the Fuse Box
Hi All,
I have '64 122s in Toronto, Canada. I pulled the motor, freshen it up, painted the bay and put it all back together again. Turned it over the motor runs beautiful. However, it seems that I have not power going to my headlights, rear lights or any other accessories. I suspect it might be the fuse box. How do I test to see if there is power going through the fuse box? Also, I have one long black wire with female spade wire connectors on both ends. I have no idea where it goes as I guess I didn't label it when I pulled everything apart. Looks like it one end probably goes to the fuse box but not sure where the other goes. It is not part of the main wiring harness. Any help to figure out if I have power or where that black wire goes would be appreciated. Thanks. Dave |

Check and clean to bright all the contact surfaces in the fuse box. Black is usually ground but others will know for sure..

1 check with a mulimeter if voltage is at the power side
2 check with a multimeter if voltage is at the "fused" ( safe) side 3 add a load, like a bulb, at the fused side and measure voltage drop over the fuse. And over the sockets of the wires. There should be no drop This fuse boxes are prone to be faulty Good luck, Kay |

"I have not power going to my headlights, rear lights or any other accessories" ...Reference Wiring Diagram: (Battery) Power to Headlight switch is supplied by way of a Blk wire from Terminal 30 of Ign Switch, where an even fatter Blk wire brings power from Battery (by way of Solenoid terminal)...so you can see Fuses have nothing to do with Headlights (except Marker/Parking/Instrument Lighting which is powered by way of Fuse 3). Remember: Color code of Wiring Diagram is your friend! Good Hunting! |

Hi Ron,
Do you have link to where I can find a coloured wiring diagram. I usually use obs2.autoscout24 but the site is no longer active. Is there a site you use? |

This might be of some help, I cant vouch for it though.
https://sometimesawitch.blogspot.com...g-diagram.html I bought an 11x17 laminated colored diagram from Prosperos garage, very useful. https://colorwiringdiagrams.com/ |

Wire colors are noted on the WD I linked, and that's all I need. I've seen some reworked WDs where someone has take the time and effort to actually draw the lines in the corresponding color and thickness for gauge, (like first WD on c1800's link) which is cute, but I cant vouch for it either... Good Hunting! |
