headlight relay

Recommended Posts

I managed to find the funky 6 pole headlight relay, and it works!  now, the question is, where does it mount??

 

Thanks,
Ken

On the inner right front fender forward of the battery voltage regulator.  If you have problems see me and my RL411 at the JCCS.

Thank you!  I guess that other relay stays then.....  front end has been rewired

Depending on just who and with what the rewiring was done you may have trouble connecting the real headlight relay !  The wiring diagram numbers for the connections have no relationship to the relay wiring tabs physical layout.  If you are at the September JCCS look me up and take as many photos and notes as you like for the correct installation.  I am in original factory configuration.

Just missed the cutoff for JCCS. Wish I could join you guys. I'm on the standby list.

Been a bit, but finally got everything connected up per the schematic, and..... nothing.  Relay clicks over but headlights don't light.....  Mike, do you have an alternate hook-up for this cursed relay?

 The relay can only be one of 2 things ON or OFF. High beams or low beams. It can't be NO beams unless there is no power to the headlights. Check for power to the headlamps. The relay  is simply a switched ground.

this isn't a standard relay - the way its wired, the current flows thru the relay coil to the headlights, the dual relays inside switch the parking lights and brights on.

Ah I assumed it was a later Datsun. On them power from the headlight switch goes to all the lamps and the relay selects a ground.

This weird relay actually has a valid reason for existence.  If you are driving in city traffic you should not use high beams.  So, put on your first position parking lamp .  If you then toggle high beams you turn on your low beam lights.  This cuts down on battery drain and gasoline waste at stop lights in high cost of gasoline Japan.

 

This relay is impossible to find.  If you follow the schematic of the relay in the above illustration it is possible to wire up an auxiliary printed circuit board with two 510 headlight relays to perform the same function.

yes, I have the relay, and its functioning correctly. the 1-2 connection (red) activates the relay correctly - however, its not lighting the headlights.  unless, the black wire is the hot wire.....

OK!  that relay schematic is completely wrong!!  Took me hours to figure it out.  quick question and i'll post the correction - when your headlights are on ( full pull ) are your front parking lights on? Pushing the blinker lever forward with parking lights on, turns on driving lights, with the driving lights on, turns on the brights - just like the manual!  does a pull on the blinker lever flash your brights?  or is mine broken?

Pull does not flash high beam or directional lights if you mean continuous blinking.  If you mean "flash to pass" pulling the stalk while on low beam, it does flash the high beams if just tapped.  A steady pull will of course turn on the high beams.

Mike,

 

pushing the lever forward locks the brights on.  looks like my pull is non-functional.  Are your parking lights on with the headlights on?
