LeX Posted February 24, 2008 Share Posted February 24, 2008 I was going to drive the z around to a friend's house and it was getting dark so of course I was going to use the lights. Car started right up and idled fine, but as soon as i turned on the headlights, or even just the foglights the car instantly died. It wasn't like the revs died off slowly, the car instantly died completely when I did this. I couldn't even flick it fast and flick it back and keep it running, the process was literally instantaneous. Any ideas what could be causing this? It's not like a parasitic drain that would slowly make the car run down and stop, but just like a smack in the face. Any ideas? Quote Link to comment Share on other sites More sharing options...

turboboost Posted February 24, 2008 Share Posted February 24, 2008 Is it just the lights that do this? Or does any electrical draw cause it to die? Quote Link to comment Share on other sites More sharing options...
woldson Posted February 24, 2008 Share Posted February 24, 2008 Like the heater fan. Also in the morning go to napa or shucks they can test it in the car. (alternator) Quote Link to comment Share on other sites More sharing options...

Brad-ManQ45 Posted March 8, 2008 Share Posted March 8, 2008 Sounds like battery is shot. Quote Link to comment Share on other sites More sharing options...
Here comes trouble Posted March 8, 2008 Share Posted March 8, 2008 Ignition switch if equipped with one maybe bad. Had an old 720 pickup that ran like crap and the head lights would go dim when I hit the brakes. Hot wired the ignition and by passed the switch and the old beater ran like a new pickup. you can check the alternators on old Datsuns by disconnecting the positive cable from the battery while the engine is running. If the engine dies......98% chance the alternator is shot...................do not try this on newer cars Quote Link to comment Share on other sites More sharing options...
