I'm not an ignition guy and I'm having a hard time even figuring out how to ask this question, but here goes... What are the sources of changes to base timing in the 260-280? Is there any spark timing control done in the ignition module near the passenger's feet, or is all the timing control done in the distributer with mechanical and vacuum advance? By that, I mean... I know they use the typical weights-n-springs mechanical advance in the distributer, and I also know they use a typical vacuum advance with an actuator on the side of the distributer, but is that it? Are those the only two sources of advance or is there additional RPM derived electronic controlled advance d…

Heres one for the major Z freaks (no offense) I have HLS-30 165246, near as I can tell from the Z registries that would make it a 06-73 production car, but I can't be sure as my door jamb tag is missing. So the question is , is it a 06-73 production car and is that an early or late 73 car? I understand from searching this and other sites that that makes a difference in which tach the car is equipped with.

Yesterday on the way home I noticed that my headlights weren't working, all the others i.e. sidemarkers, brakes, turn signals, etc. seem to be fine. My first thought was the combo switch but, I had it rebuilt by "Zs-ondabrain" (top notch if I say so myself!!) along with the turn signal switch back in June. So I moved on to the fuses, all were good. I've tried to see if there was ~12dcv at the lights themselves but couldn't get anything. Lastly I checked for 12dcv at the fuses in the fuse box. I got 11.8 dcv on all of the other light fuses but nada at the 2 headlight fuses!! So obviously the problem is getting power to the fuses/lights but, if this isn't the switch (which …

For those of you that have done a headlight conversion; have any of you modified your headlight bucket (behind the headlamp, not the sugar scoop) to be able to easily swap out new H4 bulbs without having to remove the whole assembly? I've been looking at my bucket and contemplating cutting about a 3" diameter hole at the back, but I think that the bracket holding the tension spring might be too close to cut out the back of the bucket. Has anyone successfully attempted this or will I still have to pull the whole assembly to change a bulb? Thank you,

I am wanting to improve my Hella H4's by possibly upgrading them with an HID conversion kit. Has anyone done this? If so, what kit is the best for the money? And how are the results? Thanks!

240X 1973 UK model. Hi. I have at last got down to putting my 240z back together, not that it was together when I got it. Just boxes of bits and lots of rust. I have a question regarding the indicator switch. The combination switch on the steering column looks to be the right one. The switch that controls the light / wipers etc has the same colour wires in the multi plugs that match up exactly to the connections coming from the dash loom. no problem there. The issue I have is with the indicator switch. This has a passing button at the top by the way. The wires colours {colors} on the plugs do not correspond to wire colours coming from the dash loom. I do not want to …

Sorry about this chaps. I am in the UK with a UK 73 240Z. I have a pertronix that i need to fit to the car. I have 3 wires coming through to the original coil. Black and white, green and white, and a white with a thin black stripe. All the wiring diagrams I have seen show that I should have. 2 x black and white and one green and white. I have traced the white and black back to the ignition switch the green and white appears to go there as well. the other is yet to be traced. I am a bit of a novice with the electrical stuff, my forte lays in mechanical things. if you can help me I would appreciate it. sorry about the repeat question.. Thanks in advance.. I have a…

I am having electrical problems with my 1971 240z. When I turn the headlights on both signal lights start to dimly glow. The electrical system is fairly stock. I've cleaned up the contacts on both the turn switch and the headlight switch. Has anyone seen this sort of thing before?

Recently i have noticed an issue with my idle. when i turn the headlights on it gets very rough. The in dash voltmeter reads a little over 12 without them on, and goes to 12 when on. Two days ago i noticed the voltage was getting lower and lower as i was driving down the road until the car died. I replaced the battery and the alternator and the voltage still seems low. Is there a component i am missing? The only thing that has changed since i noticed the issue was i removed the cars after market cd player which no longer worked.

Instead of plugging the carb heat line, has anyone installed an electric fan on/off switch in the thermostat housing. Got this photo from the ZTherapy thread.. That would be pretty slick place to put a thermo-switch. I bet someone has thought of this and figured out what works. Anyone?
