I want to replace all my old fuses in my 1978 Z car to eliminate any potential problems caused with the old fuses. However, I was told that SFE fuses are the correct ones to get for it. However, I checked all kinds of stores and most of them only have ACG fuses, which are longer than the fuses in my fuse box. And also places like Napa and Farm and Fleet only have like 3A, 5A, 7A, 9A, 14A SFE fuses. But they didnt have and dont think the 10A or 15A SFE fuses are even made. What gives???????????? what kind of fuses do I need for my Z car? Thanks

As I was driving home this evening, my brake warning light suddenly came on and at the same time the red (charging?) light on my voltmeter came on. The voltmeter reading also had dropped to around 12v, which is considerably lower than its normal level. The car still ran fine, no brake or other mechanical issues. The lights may have been a little dimmer but I can't say for sure. If it makes any difference, this happened as I was slowing to a stop. When I got home, I checked the fuses - all look good. Didn't see any loose or bad connections/wires under the hood. The fusible links also seem to be ok. I also tried restarting the car - no problem but the symptoms still persi…

ok I bought a 76 volt/fuel gauge for my 71 and want to do the swap when I have the interior gutted but cant seem to find a writeup on the wiring. I found one for a 260 which I assume is similar but may have different wire colors. anyone who has done this swap who can chime in or has a link to a writeup would be great.also I have a ZX alternator with the adapter plug if it matters...thanks in advance

I'm really desperate can anyone help. My 1975 Datsun 280Z straight shift cuts off after being driven and gotten warm. It gets fuel but no fire. I was told it is the ignition control module some say an ignition ignitor and some say coil. Can anyone help and if this is my problem, best location for replacement part. I drove my z to see a friend in the hospital about 45 miles and after visit driving back and having to stop for intersection vehicle cut off and would not start. After sitting for quite a spell it will crank again.

I don't have turn signals, never had since I got the car. The headlights, parking lights, reverse and brake lights work. The hazard lights work on the left side only with the dash light illuminating the left side turn indicator. From the checks I did so far I think I have a short. I have the FSM and started continuity checks on the T/S combo, then from the T/S connector to dash connector C3 and flasher unit and then flasher unit to dash connector C2. I have found that I have continuity between Green/Red stripe (left turn) and Green/Black (right turn) of the male pins of the T/S combo connector. Connectors C3 and C2 were disconnected for the continuity checks. The…

With any luck, We can all get together on this forum and figure out the weak dash light-hot fuse problems we all seem to be dealing with. I wrote in my "headlight relay upgrade harness's for sale" forum, that I upgraded all my EXTERNAL lights to L.E.D.'s. These lights use almost 1/10 of the power of conventional light bulbs. Have a running life of about 100,000 hours which rounds out to about 10 years of constantly being on, which could also equate to about the lifetime of the owner with general usage. So.. if your lights are on for (2) hours a day, every single day of the year, they would still last for over 169 years. Which is good arguement for the price of the L.E.…

I am finally getting around to installing a stereo in my '78 280Z and have a small problem. The car still had the original stereo plug and none of the wiring had been touched, so at least I am not dealing with PO nonsense. The problem I have is that I cannot find a switched power lead. The original stereo plug has six pins. They are +12V always on, Ground, Illumination, Dimmer, and LH speaker + and -. There are also two RH speaker wires that are not part of the harness. I have checked every wire and I used the FSM wiring diagram to trace them all back, but nothing comes on with the key in "ACC". I can't believe that the original radio didn't have a switched power w…

Hi, I have a 1973 240z where the wiper fuse keeps blowing. It used to work fine before I put a higher output alternator in. The original power wire is hooked up to the alternator terminal. I also have a 6 gauge wire going from this alternator terminal to a bus bar (terminal where all accessories get power) and from the bus bar to the battery. Where should I check for shorts? Did my wiring job mess something up? Thanks for any help.

Helping a buddy with his 75 280. He's taken the efi off and put on the tripple webers, etc. He says the motor won't shut off with the key. I have read where it needs a diode installed but can't remember where it would go. Anyone onboard that can give us a hand tonight? Thanks! Leonard edit: crane xr3000 fireball ignition

Can anyone recommend a good terminal I could use in which it 1) prevents the battery from draining while the car sits in the garage 2) where I can remove a quick release pin so without it in-line, the car wont start. I saw a few options on a website but cant locate that site again for the life of me.

I've read a dozen various posts on the e12 and nearly as many on the pertronix. Enough that I am not sure about either anymore. Here's the deal: I bought a buffer to polish some parts and discovered it takes way more time and patience than I have. I have an E12 80 distributor (and adapter plate) and the original point type distributor which I am willing to put a pertronix unit in. I don't have enough patience to polish both units. So, if you were putting one or the other into completely fresh L28, carbed with Z therapy SU's, a 6 into 2 header and twice pipes, in front of an 83 five speed, and you wanted complete reliability and a clean installation, which way would …

I just put a remanufactured 280zx dizzy on my 72 240Z. It seems like everything is fine, but I haven't tightened the adjusting bolt yet because I want to get the timing right. When I turned it over, it sounded like a preignition or pop inside engine, and then today when trying again, it just backfired hella loud. I'm thinking its just not timed right? I was going to take #1 plug out and make sure its TDC but didn't have the tool with me. Any ideas?
