Low beams not turning on - R34

Recommended Posts

I’m having an issue with my R34. I left my headlights on and the car battery died. I went out to jump start the car and left my headlights on. It obviously didn’t start, so I turned my headlights off and started the car again. But now my headlights don’t seem to turn on at all, and only 1 of my high beams work. I checked all the fuses in the engine bay and they all are good. I thought maybe the bulbs somehow got blown but I checked for continuity and they seem okay. I next checked the wires connecting to the bulb for continuity and they seem fine too. I’m wondering if maybe I somehow fried the turning signal stalk by starting the car while the lights were still on. 
 

Any ideas of what might be happening? 
 

thanks in advance!

Get the wiring diagram out. Remove the headlight switch loom plug and probe for where the power is supposed to be. That will tell you if you've missed something upstream (like the real fuse that you should have checked). Probe for continuity across switch terminals that are supposed to be continuous when turned on. Plug it back and in and probe to see if power turns up on the output side of the switch.

Etc etc etc.

Somewhere there will be a wire that is broken or burnt, or a fuse that is is open, or a switch that has melted or burnt in the wrong position. The wiring diagram shows you what you need to be looking for, and where.

I'm still a little confused about this.... I removed my turn signal switch from my car and I'm trying to test if it's good or not. If I understand the diagram correctly, in the Lighting SW area of the diagram, I set my switch to 1ST position and check the pins for continuity. So I put my multimeter on Pin 1 and Pin 9 and set my multimeter to resistance. I test the pins but it it seems like there is no continuity there. 

Am I reading this diagram wrong? What do the Hi/Lo/P stuff mean?

Not sure if it makes a difference but I don't have an AUTO mode on my switch. My switch also doesn't have all the same pins that are shown in the diagram. I've attached an image of the wiring diagram for convenience.

I'm sorta a noob at electrical so anything helps.

    • Ahhh, technically the way in Victoria is you are supposed to Engage the engineer (VASS) before you register the car. This is why you can't engineer only a specific mod, the entire car as a whole must pass with all modifications done to it. You then have a VASS cert and a RWC and you can then register your modified car. I did my conversion and had the registered, but off the road while the V8 went into it. I did have to drive it to Sydney to get the Emissions test for Victoria (lol - IM240) so during that solitary drive if I got defected well, it'd be moved around on a trailer most likely after that. But that didn't happen, so here I am. I am very jealous of the more lax emission laws in WA, and as a bonus you can get it done inside your own state!
    • Hey all having some issues with starting and keeping my r34 idling checked n changed the usual    just wondering if anyone in eastern to northern suburbs VIC has a fc-hako or datalogit so i can have a check over my power fc will reward with $$ and a 6 pack of your choice from Dan Murphys car is located in mill park lakes    0411119492 JET    
    • Yeh, here they want you to get approval before you start modifying. It isnt illegal to upgrade your turbo or ecu or anything like that, but you are supposed to fill out a form with a list of your intended modifications to apply for 'pre-approval' which is basically a letter from the head of the Department of Transport that says yes you can do these modifications, provided you meet such and such conditions. That letter then enables you to engage a mechanical engineer, without that letter you aren't allowed to get engineering approval on any modifications.   Then the engineers job is to make sure you comply the conditions listed on the pre-approval letter, which will always include the maximum 180hp/tonne rule, and emissions testing, etc. And can also include other things that the Dept. Of Transport just throw in, like swept volume tests etc.   Easy and straightforward if done the way they want you to do it. Hard, frustrating and expensive if you've already done the modifications.

    • Sorry - What I meant to say by 'wrong' is how far your mods are outside of the guidelines as to what can be certified. Not sure what you mean about 'pre approval to modify'. Sounds different to here. But yes, it makes sense to have another runabout to at least own while the engineering is going on if the time it takes is paramount. Given you can get a cheap runaround cheaper than a Turbo kit, if you're serious about engineering a car it shouldn't be too bad.
