Re: 6 volt relay
Jerry you need to put a shortcut for that pdf on your desktop.

Re: 6 volt relay
Good thread here. It underscores the concept that the use of relays can reduce the hazard of fire in the passenger compartment by restricting [where possible] high-amperage wiring to the engine compartment, can shorten high-amperage wire runs to reduce voltage loss and wire over-heating, and can enable the greater use of smaller gauge wiring to control the relays. All good stuff if done correctly.

Re: 6 volt relay
How many amps should you have at the headlights if you are running the stock set up. Before is add relays to the headlights. I am going to check all the wiring.

Re: 6 volt relay
Glad my original idea works so well for so many. Thanks to Mr. Seery for posting the photo. I needed the relays, as my halogen headlights were weaker than the originals until I fed them full voltage. I made the connections to the headlight loom at the left side of the radiator using bullet connectors. That way, no wires had to be cut, and could be returned to the original quickly. As for cost, I bought the solenoids from C&G for half the price at NAPA, about $25. I also used hem to design and build a control box for the top pump in my '47 convertible.

Re: 6 volt relay
Here's a *.jpg (photo) schematic diagram of Seery's Bosch relay scheme as drawn by Radio Corp. They indicate use of 30 amp relays. Wire sizes labeled indicate its based on a 6 volt system. DON'T "wire direct to batt terminal" as this diagram says .... wire to batt side of solenoid as Seery said, and DO insert a fuse as close to the solenoid as possible.

If you look at the photo I posted earlier, I have my relays turned the opposite direction compared to Supers, doesn't matter much as long as you keep track of which post does what on the solenoid you are using. Last edited by JSeery; 11-14-2015 at 09:13 AM. |

Got the diagrams and part numbers - you boys are FAST! I too have halogen bulbs in my original 32 headlights - they draw a lot of amps, so I need to "upgrade" the original wiring, but not screw it up if I want to take it back to original. I'll probably build something that hides inside the front driver's side frame rail - yet uses the stock headlight control switch for activation.

Re: 6 volt relay
Another vote for Supereal's setup. A fun weekend project, and it works great. I used copper instead of brass for the bus bars.

Re: 6 volt relay
Thanks for all the info. Working on the fog lights. Think I will do this set up next

Re: 6 volt relay
I know this is an old thread, but my question is why shouldn't you run power straight from the battery to the relay? Why use the starting solenoid instead? If you put an inline fuse, aren't you ok?
Thanks. |

Re: 6 volt relay
Electrically, the two points of connection (battery post OR solenoid lug) essentially amount to the same point, as the two points are CONNECTED directly by a huge battery cable. Voltage should be constant anywhere along that cable. It is simply cleaner and usually more convenient to use a proper wire connector and connect in tandem with the battery cable end on the designated post on the solenoid. Much cleaner than rigging some ugly connection to the battery post. And remember, fuses are designed to protect WIRING in a circuit....NOT the appliance that the circuit is powering such as headlights, a horn, or a radio, etc. DD
