and no tail lights with the headlights on. I have high and low beams, turn signals and brake lights. Fuses and bulbs are all good. What is the best way to track the problem down? Also, the hazard flashers only work when the ignition is on. Shouldn't they work with the ignition off? 1970 #4095 Mike

Title says it all. I've got a 72 240Z with a tach that tops out as soon as the key is turned to the on position, start position, and while the engine is running. Only way to stop it is to turn the key off. Pretty sure it's the tach itself and not wiring, etc because I just went through a bit of a situation with my ignition during which I tested and found the entire ignition circuit and every component to be perfectly fine. I'm about to pull the dash to replace the lights and would like to fix the tach, too. Any advice on what to look for and replace when I get the tach out and apart?

Just wanted to thank Dave Irwin for making a headlight harness for my 76 280Z. I needed to supply some plugs from the 280Z. The workmanship is excellent and my headlights are much brighter. Thanks Dave. Dave Ruiz

I have a 73 240z. Given our recent spat of cold weather (and an intervening sunny day above 40) I have decided to dig into why the read defrost is not working. I have studied all the various wiring diagrams and most of the ones i have dont even show the defrost. The grid looks good. One side's wire goes to ground, there is about 5k resistance across the grid, continuity generally checks good everywhere i checked it. There appears to be a relay in the actual wiring that does not appear in any of my wiring diagrams. A very nice 14v appears at the hot side wire to the grid when I turn the switch, but it then cuts off and goes to zero. I can hear the relay, but can't …

I can't stop from a burning a wire, burning a guage and scaring the wife thinking I'm going to burn down the garage in my quest to get my turnsignals to work. Told her not to worry cause I won't let the harley get burned.....anyway I am at my wits end and need an electrician! Need some suggestions and recommendations on who can fix my car's electrical issues in the Austin area. I have been working on this for months and I'm over my head.

so i recently aquired my first 240z after wanting one for a few years. it needs a little help but im baffled by a problem and its my first z so im unfamiliar with the car. got the car home. its a 1973 240z. had to buy a distributor cap and plug wires (electronic ignition) to get it to fire and had to put the blk/yllw wire on the coil for it to run. the previous owner is deceased so i cant talk to him and ask what he did but he was messing with the wiring for sure. i got it to run (suprisingly well) in the first two days but when i try to move it it dies. it idles excellent and revs up excellent in nutreul, and it moves fine while disengaging the clutch but once the…

I've searched but no clear results yet. I have an old 280z dizzy that I would like to use on my 240 versus an aftermarket solution. I see mostly zx dizzy solutions but I'm more interested in getting the car running rather than performance at this point. I want to use what I have on hand which is the old dual points dizzy (which is my suspected culprit) or the 280 dizzy. Prob not a popular solution but looking for economical fix for starts. If so any wiring diagrams out there that anyone knows of? Thanks

When I took my car to get it tuned up, the mechanic mentioned in the near future I should consider replacing my cap, rotor, ignition wires, and ignition coil. Granted the car is 40yrs old and everything can use a refresh or an update in components but I'm wondering if its a good idea to get it replaced or rather necessary. I'm going to place a large order from BD and was thinking of getting all the parts at once. The car runs like a champ so I'm not too sure of the benefits.

Hey guys, doing a straw poll I guess. I am looking to replace the headlights in my 240z and am considering the Hella's. Anyone have something they really like or are comfortable with. (DOT isn't a concern). I like the fact I can change out the bulb without taking out the entire lense assembly. I see some inexpensive (cheap) projection lenses on ebay but am not convinced and moreso, they look really ugly. Looking to keep it reasonable (Hella's with bulbs are $60ish each) I know that I need to get Dave's harness to keep from frying the switch and fuse panel.
