Guest oes03 Posted January 24, 2008 Share Posted January 24, 2008 First want to say hi (just joined today). I have a problem that has given me a good run for my money. I have a 1974 260z (early model). All lighting works with the exeption of the dash lights. I have checked all fuses with a tester. The running lights work fine as do the headlights (high/low). The dimmer switch was disconnected already it shows evedince that it was hot at one point. At the connection just below the combo switch the corner that houses the green/white wire shows evidence of overheating as well. The green/white wire turns hot when the switch is turned to the on position. The thing that baffels me is that the red/blue wire that I would assume was supposed to be the ground turns hot as well. This in my simple mind is why the lights do not illuminate. I have removed all gauges from the dash hoping that it was a bulb creating feed back or somthing. I also (back to the knuckle draging idiot in me) tried to bypass (ground) the dimmer switch and no luck. I have been at it for quit a while and am ready to kill a Z. Please any help would be grately appreciated. Thanks in advance Omar. Quote Link to comment Share on other sites More sharing options...
PanzerAce Posted January 25, 2008 Share Posted January 25, 2008 wait, dimmer switch? I didn't even know that Zs had one.... when you turn the lights on, are any of those wires getting current? Quote Link to comment Share on other sites More sharing options...

Guest oes03 Posted January 25, 2008 Share Posted January 25, 2008 Yes both of the wires are getting current. I figure one is supposed to be a ground but they are both "hot". Quote Link to comment Share on other sites More sharing options...
Guest oes03 Posted January 26, 2008 Share Posted January 26, 2008 Thanks for the help guys I figured it out. Looks like the radio. I dissconnected everything that I could find that was in the system had tested after each component. Just had forgot the raido. after that I used a heavy gauge wire off the spedo (in place of the dimmer) and it worked. Now I have to put it all back together and test each component as I go. With the spedo connected the dimmer works. What I learned is that I got to personal (angry) with the problem and failed too realize that with a lightbulb in the system that is the link to make the system "hot" (elec 101) I am a dumbass. Once all lightbulbs or systems were removed I could not get a ground or current from the red/blue wire. well I hope this may help someone out ther It was not a total loss though need to replaces some a/c ducts and fix some rattels while it is apart.
