The engine inspection-work lamp has a round rubber ring under the white plastic bulb cover... It keeps the moisture out, and the bulbs last longer Where can you get new ones? I was thinking of making one using plaster-of-Paris and the usual black RTV silicone stuff. thxZ

I noticed these two overheated connectors to the right of the glove box (above passenger's right knee in the U.S.) on my 240z when I got it: To fix them I soldered the four crimped connections between the wires and the two connectors to eliminate further overheating. I also slightly squeezed the gripping side edges of the two female connectors to grip harder on the connection and sprayed the connectors with deoxit, following up with dielectric grease. I understand that one of these two white wires goes to the battery and the other one goes to the alternator and between them they carry all of the current that goes through the fuse box. I have three questions: 1. Ar…

I replaced the stock coil on the driver's fender with an MSD Blaster 2 with MSD ballast, and noticed the stock coil has a condenser mounted on the ballast. There is what looks to be a second condenser on the distributor itself. Is it normal to have two? Should I replace both with new units?

I have a stock 78 z except I have installed a Mallory #4563901 distributor. I have not started the engine yet as I am building the engine up around a new long block. What are the capacitance ratings for the condensors on the alternator and the coil? Also, the Mallory instructions require a ballast resistor in the curcuit between the ignition switch and the coil + terminal. I cannot find any reference to a ballast resistor in my manuals. Was there a ballast resisitor put in by Datsun on the 78 models? If so, where is it located?

So hello and thanks! My early 260Z Has some problems i'll give you the specs.. *Stock motor early 4 screw SU's rebuilt by ZTherapy . *Mallory Unilite Distributor mechanical advance and some old Mallory coil that gets pretty warm when running. *I added light and turn signal relay kit some time ago. Everything else is stock. My problem is the coil is only getting like 9 to 11 volts max sometimes and makes me think i'm no getting good spark. Also sometimes car will crank fine, but won't spark unless unless I add a Jump box. What should I do? Is there a newer better ignition system I should be using that will help clean up and help car run better? Is there a shop or any one …

Previously my Z's original oil pressure gauge worked in the usual manner: at idle hardly no pressure shown, at higher revs the pressure would go up. I knew that it is the way these often work and wasn't too concerned. FYI I have Mallory Unilite dizzy and before it was installed with Mallory Coil with NO Ballast (this was done by the PO). Tach wasn't hooked up and wouldn't work even if I connected it. Then the head was off for porting and new cam. Soon after my Mallory coil went bad and I got a new MSD Blaster 2 and Ballast. I installed them and got the tach working too. But next thing that happened was that the oil pressure gauge now works the opposite way: at idle it sho…

Alternator has bit the dust. I've done the headlight upgrade and I've got a pretty high amp stereo. Yesterday when running the stereo, lights, and windshield washer, the amp gave up the ghost. It was about the only mechanical component that hadn't been replaced or rebuilt. Since I'm running a higher load with accessories, I was thinking of making a change from the 78 60amp to the ZXT 70amp. I'm thinking this a good step without pushing the limits of my wiring. I've still got the OEM fuse box and fusible links. I'll upgrade those later, but I need the car back on the road, ASAP. Any thoughts would be appreciated. Good plan and step?

Ok, so I have a 73 240z all stock. I currently have a blaster 2 ignition coil. The Tachometer worked with the original ignition coil. However does not with this one. I bought the 8920 adapter. However thats usless unless I buy the 200+ dollar 6A/AL. anyways, my question is to get it working what are my options besides buying the 6A. even if its a little more money. Like could I buy a MSD dizzy and a tachometer from a 280z or zx. or even a tach from speedhut. I kinda dont really want the adapters. and I want to avoid adding extra wires. So i guess you could say im looking for a almost just bolt in solution. Ive searched the thread over on hybridz but their replys seem to t…

Just bought a 77 280z. I noticed the spark plug wires have fine print on it says "Sumitmoto 1977". Does that mean my car still using the original factory wires after 36 years?! :paranoid: The wires looks okay though. No crack or anything. May be I should get some new NGK?

Yes I have searched the files for things to check... Recently my turn signals have stopped working. Here is what is working 1. Headlight switch ON: headlights on, taillights on,No front running lights,No Front Sidelights. 2. Emergency Switch ON: Front Flashers ON, Rear Flashers ON. 3. Turn Signal Left or Right: No Turn Signals Things done so far: All bulbs have been checked for breakage, all sockets where cleaned, and checked for rot. Circuit breaker for flasher appears good, and I don't have a dedicated turn signal CB as far as I can tell. Fusible links all appear intact, give a good continuity check. Turn Signal Switch circuits all check out good per FSM. CLeaned, …

This is the latest problem with the '72 Z I bought back in the spring. For several months after buying my Z the running lights worked fine. Recently I drove the car to a restaurant for dinner and left the running lights on by mistake. They were on for about an hour when I came back to the car. I cut them off, started the car and drove off. As I was driving I noticed the dash lights were not working. I tried the dash light control and no luck. At the time I did not think about the running lights. When I did, the next day I checked and they were not coming on either. I checked fuses which turned out to be good. Before I really get into trying to run this down, are t…

hey guys so i just jumpstarted my car (cuz i left the lights on...otherwise the car's been running great recently) it was after that that i noticed i was overheating (like almost in the red) i checked out the radiator while it was still running and the fan wasn't running. is it supposed to turn on while the car is running or just once the engine is turned off? it looks like everything else works (no leaks or anything) but i havent checked out the thermostat or anything like that cuz i dont really know anything about how those work...womp womp... anybody got an idea of where to begin looking for the problem? oh also the temp gauge rises mostly when im idling but once i dri…
