no head lights

[blackjack]

Can some one give me some advice on trying to figure out how to get the head lights to work again on my 240z. Is there a relay on the passenger side kick panel that could go out? Drive lights work fine out but the turn signals only work in the front not the rear?

So from what I got from another thread the light switch on the left should ground the wire so the head lamps come on correct?

Headlights:

1. There are no factory installed relays in the 240Z.

2. Get a wiring diagram. Look at the link below for Blue's website. Heck, even a Haynes manual would give you some idea of how the circuit is wired. Use the diagram and a multimeter to determine where the circuit functions.

3. Search this site and Zcar.com for all sorts threads on the same subject.

4. Clean the switches. Just be careful not to lose any parts.

I already have all of this and for the life of me I can't figure it out. I have done plenty of wire on other types of vehicles and I just can't under stand why they wire these cars like this.

The other problem is the previuos owner hack the wire at the column and the colors don't match any more. the wiper motor has no power either. Is there a way to get the dash lights brighter?

Ok I went out and checked the wires at the head lights there are no hot wires, I check the wires/ two fuses in fuse box and still red wire is dead. Both fuses have continuity also. I check the red wire going to the column and it's dead as well. Is there a fuseable link for the head light wire some where in the engine bay?

On the early 240Z, the supply side of the fuse block should be a W/R wire.

It starts at the alternator A terminal, goes via a FUSIBLE LINK to the fuse block and feeds 5 fuses, headlamp L and R included, and then to the AMMETER.

Check for voltage at the A terminal first, then see where you lose it from there.

I found the thread on the combo switch repair and I have lights. I am short a front turn signal. I will take apart the turn signal switch again and add some solder to the contacts.

Rather than adding solder, just use some contact cleaner. I had the same problem...I wasn't getting the right blinker but the left worked fine. I took the switch off just enough to spray contact cleaner inside it, and then worked it back and forth and both blinkers work just fine now. They oxidize the contacts inside just like the headlight switch. I had problems with the headlights and marker lights too, and after cleaning the headlight switch, the headlights work but the marker lights are flaky and work sometimes and other times not. I'm replacing the fuse block and going with the relay harnesses that Dave Irwin sells and hopefully that will solve the problems. If not, at least I'm starting with something fresh and better instead of more than 30 years old and rotted/worn out/eaten by rats.

Obvioulsy, you don't get the purpose for adding the solder. It doesn't matter how much contact cleaner you spray on it, if it's worn to the point where there isn't enough material to make proper contact. Maybe that's why your marker lights are 'flaky'.

I have two turn signal and combo switches from later model cars probably 260z that are in my 240z. The first one I clean up for the turn signals had very little buttons for contact points the second one I cleaned up looked really good but where carbonized. So I took the best of the two.

I went and bought the 3 pole double throw switches and will wire those in so I can get the current load and the wiring done correctly for the turn signals and brake lights.

I already have relays in the engine bay that I need to wire up for head lights, coil if needed and one for clean power for the interior dash lights.

Yeah, I was just saying to try some contact cleaner in the blinker switch before adding solder to it because its easier and quicker, but I guess it doesn't hurt, and if his are really worn out, then solder is the best choice. My marker/taillights are flaky because I have a problem with those green wires in the fuse block and in the molex connectors and making consistent contact. I'm waiting on a new fuseblock from MSA to fix that problem.
