Hello all, I have been reading up on the pros and cons of the various electronic ignition upgrades available for my stock 1972 240Z and I am leaning towards the Crane Cams XR-3000. I checked Summit Racing and noticed that there are 2 different part numbers. Can someone please confirm whether the 3000-0231 is the one I should buy if I want to do this upgrade.

Okay, my situation is this. I got original antenna when i bought the car but the mast was busted. Now i've purchased another motor antenna with mast on, BUT they are different (see the picture) Will both fit in 240Z? AND will the mast from the left one fit to the right one? There is a problem here, left one has pristine mast but engine seems to be busted, it sounds like " wank wank wank" when the other sounds "buzzzzzzzz" What should i do?

Does everybody's stock turn signals blink faster than most cars? Mine is faster on the tach gauge than the blinkers themselves. My Dad says older cars are like that but he spells Datsun with an "O". They work fine just faster than I'm used to, like there's a blown bulb. Just curious.

As an alternative to the pricey oem-style power antenna, I figured out a switch wiring setup to operate a newer automatic antenna (it goes when the radio is turned on, and down then the radio is turned off) to work using the wiring available in a 280Z. Below is the switch diagram I figure to use, which requires a DPDT, center-off momentary toggle switch and two of the three wires. The red wire is the main power wire to the antenna, and the blue wire goes to the radio's power antenna connection. Ground on the antenna goes to the chassis of course. I will figure out a relay setup using two wires and the factory antenna switch ( SPDT center-off momentary.) thxZ

I just finished resolving a short on fuse #3 (turn signals and gauges), but i am still showing a constant 1 volt drop on that circuit. I've done continuity tests and checked resistance on every segment that I can identify, and the problem appears to lie somewhere between Connector 3 and Fuse 3. Otherwise, everything appears to be functioning normally. Can I safely ignore the voltage drop, or do I need to keep digging? thanks, tony

My turn signals and exterior lights all work great, except the green signal arrows in the tach are reversed. Any suggestions? My tach is also intermittent. Related? '73 240z

I've been having problems with my 72 240Z. It started this past winter months, Came back home from Florida mid Feb.removed the coil wire and cranked it to circulate the oil, hooked it coil wire up, and it started. A month later, no start, dead battery. Recently I replaced the battery, and put in a new starter which I had for my other Z (10/69 FairladyZL). I installed a new voltage regulator from Motorsports Auto. It started right up. Drove it around, everything was fine, gauges working, battery charging. A week later, I went to start her up, heard the click of the relay, and nothing, except the noise of the electric fuel pump, the amp gauge was negative and the Tach was b…

I am in information overload here and I am looking for setups that have worked for others. I have searched and searched and with all the info out there on all the Z sites I can't determine what actually worked under what circumstances. I mean seriously, you can prove and then disprove the theory of relativity within a post or two in some of these threads. The short of it is that I am in the process of connecting an MSD 6AL with MSD Coil to a 280ZX Distrubutor in a '72 240Z with the original tachometer. The more complete version: I recently picked up a somewhat used Rebello 3.2L with triple Mikunis and have already put it in place... along with replacing the entire driv…

I'm in the process of installing a Pertronix on my '72. I have read so many conflicting wiring instructions it makes my head swim. One consistency, though, is don't leave your ignition on without the engine running or you canburn out the Pertronix. I can imagine a simple circuit, but I cannot design it. A relay that shuts off power to the Pertronix if it dees not sense an ingntion pulse within a minute or so. Resets with turn-off of ignition power. One of you geniuses out there can cesign it so it can be built for about $10, and save the rest of us the replacement cost several times over. How about it? BAM
