Excuse my inexperience, after reading some previous threads, I know some of you got pretty good at this... Little background: Was in the shop tracing the wireing harness, and shorted a wire against the starter block. The car did not start after the short. Inline Fuse (Fusable Link) is good, no obvious blown fuses. I have been trying to get it to start by connecting the two closest terminals on the starter, but have so far only produced a "Whrrrrrrr"ing sound (It doesn't engage?) Haven't found a junkyard that has a s30 or 280zx starter (car was L28 swapped), and am going to see a place that rebuilds starters tomorrow. Anyways, before that, I thought I'd ask... By c…

Ok I have what could be a dumb question. When I hit my brakes my brake light on the dash comes on. Just like if I where to pull the e-brake. Is this normal. By the way it's 74 260. Just bought the car so I was not sure.

Hi, I had been having a problem with my turn signals. My Hazard flash work but the turn signals doesn’t. It is not the flasher because I tested it. There is Green wire that goes into the T/S Flasher but I read 10.5 V, and I think This may be causing the problem. This Green wire goes to the Hazard Switch and accordingly to the diagrams, this green wire gets power from the voltage regulator. Do you think the fault might be in VR? Thanks

My set up 240z 1972 with stock ignition single point, L28 n42 block and n47 head, headers, stock SU's three bolt (rebuilt and all adjusted included float levels) car presently runs well but I suspect a weak ingition due to fouling plug 3, changes in plug presention with and without ballast (see below), noticable power increase with ballast bypassed (see below). 1. My consern is that I have an eratic misfire or eractic weak spark resulting in loss power. 2. manifold vacuum 12 hg inches consistantly at idle (too low for spec) (all valves have been adjusted cold and hot). no white smoke, barely noticeable black smoke at wot on freeway. 3. cylinders 6 and 5 presently s…

One headlight works, both hi-beams. I rebuilt the switch to no avail. Ordered HLH and PLH (no taillights either) from Dave, as well as the MSA fusebox upgrade for the 72' (short pigtail, I believe). This is supposed to be a "Plug and play" upgrade, and would be... but I have an extra wire from the orginal fusebox. It is possible that the previous owner tried to mod the OE fusebox to prevent a meltdown. I believe this z came with a halogens, and at one point had a prettty nice sound system. Whatever it is, no meltdowns running halogens all night accross Canada. The "extra wire" comes from the rear of the fusebox, and is connected to a metal bridge, spanning one side of…

Hello All, I'm working on the front headlight mounts and Assembly's. They are really rusty and corroded so I figured while I had the time I would glass bead them, powder coat and replace all the rusty hardware. The trouble is with the the plastic round nuts the adjustment screws turn into. They are all dry rotted and falling apart. Only 1 still had the rubber caps on them to protect the back side. After a search in the forums I cant find any info. I don't want to take a file to the mounts to use the newer square style if I don't have to. Does anybody know if the original style is available somewhere? I've called MSA, Black Dragon, Courtesy and a bunch of others with …

I have a 1972 Z w/manual, stock distributor, three screw hitachis that I recently purchased. Car has been driven little in past 5 or 6 years. Have had cold start and idle problems: Cold start - full choke applied, takes 10 to 15 attempts to get it started Will not idle below 1200 rpm, and I need to pull the choke slightly, otherwise when returning to idle (like when coming to a stop) the engine dies. It will restart immediately and sometimes idle, but will die again at the next stop. Off idle and driving - the car seems OK replaced: Battery (would not hold a charge) Points (heavily pitted) Distr Cap condensor Spark Plug wires Fuel Filter Also: Adjusted valves checked p…

Hello all About two weeks ago I upgraded my headlights to H4 replacement bulb type with a high end 55W bulb. Today I took my Z out for a nice long ride. About forty five minutes into the drive the driver's side headlight went out. About two or three minutes later it came back on. A couple minutes later it again went out and stayed off for about two minutes. Then came back on once again. Anyone know what this can be? I've read someplace that I should update the relay or something electrical as the old wiring can't take the load? Any help would be great. Jan

OK I am working on my 72 and the electrics seem relatively un-molested. I pulled out the aftermarket radio and the center console. I removed a couple splices and wire twist jobs that were obviously "aftermarket". The rest looked very clean with a lot of unused spades, bullets, and connectors. Dillema: When I removed the center console, the three connectors were already unplugged. They were: 1) Four Pin square layout (defrost/belts?) female 2) Flat 2-pin 2wire (choke lever) 3) Flat 2-pin 3-wire (belts/defrost?) For the life of me, I cannot find the mates for all of these in the fusebox area or anywhere behind the HVAC panel. There are plenty of receiving conne…

Currently we are working on getting US Tail lamp assembly made at same quality as the limited production Europeantail lights. Since Euro ones are very expensive, and very few were made (MSA has few now also) , we are working very hard to get the cost down. Our minimum order is 500 sets to get the cost down, so it will be a major investment and a space taker as well for us......... Price target/goal is at rertail price of $399 a set. Considering tipycal tail lamps for 300ZX are 200-300 a side, this should be a great pricing....... What do you guys think?

Many threads on the Pertronix install and the option of going with the 1.5 OHM coil w/Resistor or the 3.0 OHM coil w/out the resistor. Tech support at Pertronix recommends the latter (Part 40511) - but this would provide full battery voltage in RUN to the Tach. Does anyone have this set-up and experienced any issues with the stock tach?

My car does not turn on by turn of the key . I'm able to turn it on by bypassing the starter. I changed the key switch but no answer. When I turn the key it makes a little click by the fussible links. The car works well , but I hate jumping it everytime I drive it.
