Re: fuses 56 ford customline
My 55 didn't have a fuse block, and I believe your 56 is the same. I would check the connections on the back of the headlight switch first, then the connections where the wires for the directional lights connect near the steering column. Also, check for good grounds at each light.

Re: fuses 56 ford customline
I am restoring a 56 Crown Vic and have removed all wiring. There was not a fuse box anywhere in my car. I will probably put an aftermarket harness in when I reassemble.

Re: fuses 56 ford customline
I know there are fuses on the HL switch, mine went in the trash when I rewired the car. I ran into more than a few fuse holders under the dash too. You'd have to trace the wires back from the lights, good luck!

Re: fuses 56 ford customline
Also, the only other fuse I'm aware of is on the overdrive relay on the firewall under the hood (if so equipped).

Re: fuses 56 ford customline
Tail lights, brake lights or backup lights?
There is a fuse on the back of the headlight switch and check the bulbs too, they could just be burned out. The 50's Fords don't have a fuse box, just a few inline fuses and some thermal circuit breakers, especially for power options like seats & windows. . Last edited by dmsfrr; 05-31-2017 at 11:08 PM. |

Re: fuses 56 ford customline
The fuse on the back of the headlight switch is for the interior lights. There is no inline fuses for other lights in the wire harness.
If both lights do not work, there is probably a single bad bullet connector where one wire feeds both lights, could be the one that is located in the harness just above the transmission hump (behind the radio). Sometimes the connector gets a little loose, dirty or corroded. Body ground is important. I ran a separate ground wire with green insulation from the firewall ground screw under the dash all along the rear bumper harness to the back of the car and used it to make ground connections to the taillight housings, backup light housings, license plate light socket and the fuel sending unit. |

Re: fuses 56 ford customline
The back-up lights are powered by the neutral start switch (located at the base of the steering column on the engine side of the firewall). The switch could possibly be out of position (it can be adjusted by rotating in the mounting slots) or there could be a wiring problem between the switch and the lights. The best way to trouble shoot it would be to check the voltage at the switch (with shift lever in reverse) to be sure it is closing and in proper position. If there is voltage at the switch and not at the light, the trouble is somewhere in the wiring between the switch and the back-up lights.
The license plate light is part of the tail light circuit and has power when the light switch is turned on (powered by either the parking light or head light position of the switch). If your tail lights work (not the brake lights, but the tail lights) then the light switch is probably okay and there might be a wiring problem between the tail light wiring and the back-up light socket. Good luck. Wiring can be a very frustrating thing to chase down. Dave |

Re: fuses 56 ford customline
I think 56yblock is talking about the tail lights when he says back lights, and not the back-up lights.

Re: fuses 56 ford customline
Reading a wiring diagram can be its own brand of torture. Just be glad you aren't working on a newer car. These oldies are really simple in comparison.
Tail lights ~ There is a black wire that runs from the "R" terminal of the headlight switch to the left rear tail light. Near that tail light there will be one or two connections for black wires to the license plate light and right rear tail light. Use a volt meter or 12v test light to check for power at each connection, starting at the "R" terminal of the headlight switch. The '57 wiring diagram at this link should be 99% the same as a '56, which does not have a dash gauge voltage regulator. http://www.oldcarmanualproject.com/t...re5765-195.jpg Yes it is... If the light fixture mounting screws or light sockets are loose or rusty, not well connected to the body of the car, the bulbs will not work. . Last edited by dmsfrr; 06-02-2017 at 05:35 PM. |

Re: fuses 56 ford customline
If there is no power on the "R" terminal (black wire) when the switch is in the 'on' position the switch is bad.
If there is power on that terminal, the problem is somewhere closer to the lights. The fuse on the headlight switch is for lights inside the cabin of the car, not outside. |

Re: fuses 56 ford customline
Funny this should come up right now. We just got the backup lights on my '55 T-Bird working. It has new aftermarket backup light housings, and when I looked, there were no bulbs in them. Looking further, the wires were not hooked up to anything. Looking really carefully, we found that there were no wires at all to hook the backup lights to.
No expert, but apparantly my car did not have factory back up lights. They must have been an option. What is strange is that there were no wiring provisions for them in the original wiring that is on the car. We installed wires for them from the new neutral safety switch that was just put on the car a couple weeks ago. Whee! Now it starts in park and I have back up lights. |

Re: fuses 56 ford customline
That's the way the factory wired them. Parking lights on with the headlights didn't come along until sometime in the 60s, I believe. You can wire them to be on with the headlights but you should use a relay to keep them from stealing brightness from your headlights.

You may have to release the switch, with all the attached wires, from the dashboard to test it. There are a couple tricks for getting the switch out of the dashboard. There are photos and some instructions at this link... https://www.fordbarn.com/forum/showt...adlight+switch Removing the switch isn't the easiest thing to do. To help make sure you do or don't need to take the switch out... first check for 12v power in the black wire connections at the left rear tail light. Use a volt meter or 12v test light. If tail light power is there you don't need to check the switch in the dash. . Last edited by dmsfrr; 06-03-2017 at 02:39 PM. |
