'72 510 headlights and turn signals

[AceOfDiamonds0]

I figured I better post something here before I go chasing wires around in circles.

 

'72 510, the low beams work on both sides but when i turn the high beams on, both left headlights go really dim and they're brand new.

 

Now I could probably figure out the turn signals but I might as well ask.

 

The turn signals turn on with the switch for the headlights but do not flash if i use the turn signal switch on the steering column. Are they both on one relay? I haven't even looked at the fuse box yet so it might just be that but just in case there's more complications I wanted to ask.

headlight ? try reseating the connector to the fuse box and the reseat relay thats on the rear side of the strut tower.

 

your emergency flashers work?????? yes or NO You still have the emergency switch installed? If not they not going to work If i remeber right.

 

there are 2 aluminum looking cans under the dash by brake pedal. they will have 2 pronges You can swap them and see if anything changes. or reseat those also.

Tried the fuse box and the relay and still the same.

 

Here's my problem:

 

Low beams:

 

High beams:

Oh and as far as the turn signals go, I still have the hazard switch but it doesn't work. I'm in the process of cleaning all the terminals and connections I can find.

I'm wondering why your p/s main headlight isn't dimming when you turn on the high beams.  Something isn't wired right.  The D/S high-beam looks like it's series-wired through another bulb.

 

The turn signal shouldn't turn on with the headlights.  The parking light should, though.  The turn signals will NOT work if the hazard switch is disconnected or broken, as the turn signals wire through the switch when it's in the off position.

[AceOfDiamonds0]

I'll see if I can get the hazards to work and check the wiring for the bulbs.

[AceOfDiamonds0]

Is there someplace that I can find a full wiring diagram for a '72 510? I'm very temped to just rip all of the wiring out and redo all of it because its starting to look like an electrical nightmare with all the wiring issues i have to fix lol!

[AceOfDiamonds0]

Ok so the hazard switch seems to be ok and i can hear the relay actuate but only intermittently. Even when the relay for the hazards actuates, the turn signals don't even come on. So I'm still kind stumped.

Since you are having a problem with both left lights, you might check the fuse for that side. Make sure its clean, and the fuse is good. Else its probably localized to the wires at the headlight there...

 

As far as turn signals. They are so very easy to wire up wrong on a 510. You probably just have the wires mixed up.

I'm in the process of cleaning all the terminals and connections I can find.

this is what I did to the 72 4dr, found a burned terminal at the fuse block. As you clean the connectors, make sure you put some die-electric grease on them so they won't corrode up.

 

to clean the female spade connectors, I use a finger nail file, had to file one side down a little so it would fit into the connector. Also you might want to get some lemon juice and soak your fuse block for a few hours. Then rinse it with warm water then blow dry. 

 

is your 510 a sedan or wagon, just wondering because theirs suppose to be a different s, not sure what.

and do you own a multi-meter ? If your working on wiring, you should get one if you don't, saves on a lot of guessing.

[AceOfDiamonds0]

Ok I'll give that a shot.

 

It's a 2dr and I do have a multimeter lol.

 

Oh and I noticed that one of my turn signals in the front is wired backwards. The right one is brighter than the left one and they're both brand new!

  clean those contacks.

 

I didnt have a emergency switch on one car so I took it from another car and installed it and my turn sig and Emerg Flashers worked.

So what I did is have the Emerg swtich pushed IN (OFF MODE) and I ohm cked wich wires were shorted and I just used jumper wires in the other car to get my turn sigs to work (of caose I had no Emergency flashers but how many 510 owners really use them0
 

[AceOfDiamonds0]

I just bought a 12 circuit painless wiring kit for it. The car only has half the wiring that it should and half of that is wired wrong anyway.

 

Now I dont have to deal with the hazard switch and all wires will be new! I might have to rig something up for the headlights considering the kit only comes with the wiring for a left and right headlight and I have 2 left and 2 right.

[banzai510(hainz)]

for the headlights I would put in a H4 harness . all you need is the pass side 3 prong connector to work right.

As for the turn sigs. clean and find the proplem.

 

I seen to many Painless harness come thru Ratsun never to be completed and car sold.

 

figure it out.

[datsunaholic]

Painless harnesses are anything but.  Better than nothing though, but they don't come with any correct connectors.  Ends up looking like a hack job, any I've seen on non GM cars.

[banzai510(hainz)]

my mistake you can buy a H4 /H1 harness. means a 4 headlight harness.

Long as the pass side 3 prong connector works that will plug into the new harness and your done. it will have 3 relays.

 

wonder if the high lamp is good? you ohm it out? driver side lamp?

 

just find the grounds and ck it out  clean and recheak

[AceOfDiamonds0]

Got the wiring kit installed and wired up with almost no issues. I got a wiring diagram and had to do some cross referencing but it wasnt too difficult to figure out.

 

No it didn't have any of the right connectors but I did get a hold of a quick connect terminal kit and wire loom so it actually looks pretty good.

 

Oh and EVERYTHING WORKS! The painless wiring kit IS painless and it does not look like a "hack job"!

Say wah you bought the dime huh :thumbup:  We should try to have a meet this saturday if your not working!

[AceOfDiamonds0]

I really want to take it to a meet but I still gotta sort out the suspension. Should be done by this weekend but I have to work Saturday so I can't this weekend unless we do it Sunday.

[ArchetypeDatsun]

Yeah I'm down.

[AceOfDiamonds0]

Ok I'll post something in the meet section.
