Hi, I've been through some forums before posting this. Got a 77 Z, one day had to activate hazard signal because of very slow traffic... I press the button and instead of activating the signlas i got a strange noise "brzz" and saw the battery indicator going down to "0". Right after i also noticed the loss of blinkers, but don't know how or why, they came back to life by themselves. Status is that: When i activate the hazard, no signal and hazard are not working. When i activate blinkers, they both work, but if i press the hazard signal, they will stop working. Oh, my battery signla is still akward, sometimes showing full battery, s…

77 Z Since i own my car, i saw from time to time battery indicator going down to "zero" and coming back alone above 12V. This while driving. But i was able to observe following routine: I enter in the car, Indicator shows 12V Put key and turn ignition to "ON" position and then...bye bye! Indicator shows "0" I would drive few miles then notice suddenly that it indicating 12V again. Engine still on i've been trying to activate different instruments to see if they were having an effect on battery indicator value. The only 2 that have effects are: - ventilation: if i activate the fan, indicator goes to "0" and then the indicator will never come b…

Please help electrical gurus. ‘73 240Z. Found two cut off wires on body near the middle of trans. Both yellow, no stripe codes. I though they could be the reverse lamp switch, but that’s wired up & working. i pulled on the wires and they’re male spade connectors on the side that were cut (not by me obv). Leaving behind two factory female spade connectors in plastic tubes. Any idea? I couldn’t find anything on the wiring diagram that made sense to me. Thanks in advance. -R

The oil pressure/water temp gauge on my early '71 240Z no longer works. I've replaced sensors and done all the usual tests for meter deflection (shorting against a ground) and it's kaput; I guess the gauge's voltage regulator. I have purchased a used replacement gauge on ebay that the seller listed as "working". Does anyone have a suggestion on how I can check out the replacement gauge before I start tearing the dashboard apart. I'd hate to go through all the aggravation of installing a broken gauge. Thanks

Quick question for you folks with a volt (not amp) meter. What does your guys' volt gauge read when its sitting off in the garage? Mine is sitting at a smidge over 12v - is that correct? It seems lower than I remember, but I could be wrong.

Just wondering if anyone's using the new 123igntion distributor on an L24 that you can tune via Blue Tooth? I'm running triple Weber 40s with an E88 head in my 240Z for street and track events. Timing's always been a bit of an issue. Seems like this would be a game-changer if it actually works as well as I think it could. Thanks for your input.

My head is spinning from scrolling through the FSM and web forums looking for information about my problem. This problem is intermittent but seems to be happening more frequently. This evening, the Datsun decided it was going to stay right where it is.. None of this started happening until recently. My symptoms are: -starter will turn over, but.. -temp, fuel and oil pressure gauge do not work -fuel pump doesn't run/pressurize the FI system (my pressure drops down after I turn the car off, inline gauge attached) -radio and blinkers do not work -idle has become very rough and after warm up, the CHARGE light comes on and the BRAKE light dimly lights up (with E-brake up). 2n…

So I am noticing my dash light were a bit bright, turned the dimmer no effect. (I don't mean excessive bright just bright enough for me to want to play with the dimmer). I don't know if this started AFTER the dash pull or not. I am pretty sure I check all the electrical (including the dimmer) after the dash pull, and all was well, but I am getting old so anything is possible... Anyway 1st order of bus was to look a the wiring of the dimmer, could I have somehow goof that. start by unplugging, no effect full power to instrument lights.. hmm.. So since the dimmer is just a variable ground, I figure the lights are getting a ground from somewhere they should not be.…

Hello, I have a query for 71-73 240z Hitachi AM/ FM Radio owners both current and prospective. Does it matter to you if the the insides of the radio are not OEM? If the obsolete 40 year old circuitry is swapped out for new digital innards does it make a difference as long as the exterior is identical to OEM? Thanks, daniel p.

Hey all, Running into some issues with what I think is the alternator on my 71 Z. I got my battery tested to find that it's not the culprit. Before starting the battery voltage is around 12.82 V and when the car is idling the voltage is at 12.11 V. The car idles lower than I'd like (500 rpm) and thats at full choke. Battery is drained a fair amount after running it too. I haven't checked the spark plugs yet, but I think I'm gonna check them once the car cools down, but I'm fairly certain it's the alternator. Is there anything else I should check before ruling it out to be it? The belt on it is tight and the voltage does go up a little (12.35 V) when I give it some ga…

For the longest time, I have watched the evolution of the Led 7" round headlight technology and recently decided to upgrade to a set that fairly well mimic the look of the stock glass sealed beams at a reasonable price. I did not want the projector Hid look, too high tech looking, plastic, fan cooling, or a blue light hue. The set I found was from Vintage Car Leds who aim their products at the customer who wants the oem glass look with the advantages of Led bulbs. I chose the 3500 series of their lamps which are moderately priced, and appeared that with the bulb (4000 LM) / heat sink installed (no silly fan) would fit in the confines of the S30 housing. Of …

Cap, rotor, wires are all readily accessible and I have new ones on hand. I am finding pick up coils and reluctors but can not seem to locate a vacuum advance unit or the springs for the advance weights. I have found some Cardone reman distributors available that have all those pieces included but thought it would be neat to retain the original distributor assembly that was installed at the factory. I did get all the pieces for the alternator which also was the factory installed unit on my resurrection project. I am not a big fan of Cardone reman products and looking for some helpful tips. Obviously these parts must be available if they are being installed on the rem…
