Emegency! Headlight Problem Help Pllzzzzzzz

[Qantas]

hey all. the mrs has an r34 gtt with parker lights stuck on even after theyve been turned off, thought it might have been the stalk so i took the stalk/switch out of my r34. didnt fix the problem now her batteries dead. any1 know or have any ideas on wtf is causing this. had a look at relays but have no idea if any of those may be giving me issues. any info would be good . thanks guys.

not sure on 34`s but its very unlikely to have a relay running park lights as its such a small load. do the lights go out when stalk was disconnected?

no added lighting additions that could be at fault? lights hooked to cd player or anything like that

most nissan stuff is switched on the earth side. so when you are turning on the parker lights you are earthing one side. the other side generally has ful time + or just + when ignition is on. I guess parkers are the former (always +) so you can leave them on if you need to.

while this is safe, it means that if the earth wire to the headlight is damaged and touches bare metal somewhere, it will turn it on. I guess that is what happened.

anyway....if you want to work it out yourself grab a multimeter. you should expect to find continuity (0 resistance) between the negative at the globe and the chasis, even with the switch off (if you don't the light should not be on!). From there trace back the wiring until you find a break/damaged wiring...must be there somewhere. when you've found and repaired the wiring you should no longer have continuity at the globe unless the switch is on.

or, take the globes out and take it to an auto sparky at your leisure.

My R32 has a separate switch, just near the main light switch, that can turn the parkers on (presumably it's for when fog lights are fitted). R34 doesn't have a similar switch, does it?

checked all wiring. seems fine. been told by some people and an auto elec that it defo sounds like a relay considering the parkers, tail lights and dash lights stay on aswell at the same time. anyone know where these relays are hidden. been told they may be under the dash. definitly not in the fuse box under the bonnet, only main headlight relays under there.
