Hi, does anyone know when the little red light in the speedo gauge that says "brake" on it lights up. Should it be linked to the handbrake or is it just a brake warning light. Just mine has never lit up and wondered if I needed to look behind the gauge at changing the bulb or checking the wiring to the handbrake. Thanks

I have put new connectors on the voltage regulator wiring. I wired the connectors exactly as they were before going to paint. One of my questions is why are there only 5 wires coming from the wiring harness, but 6 coming from the voltage regulator. The white wire with red stripe (IMG_7889.jpeg) from the voltage regulator does not connect to a wire from the harness. Also there is a single black wire with white stripe (IMG_7890.jpeg) coming from the harness that does not appear to connect to anything. Anyone know what the wires purpose is? Greg

Hey, the turn signals in my 73 240z have been intermittent and I finally decided to bite the bullet and try and separate the turn signal assembly and I noticed that the little ball that's supposed to be on the end of the spring was missing. Basically #2 in this picture Anyone have any idea what size that is? It might just guess and try and buy a few small ones

The relay diagram is somewhat confusing to deal with as a reference for what's actually there. Ultimately, the one that is unknown is the 25230-89914 relay The reality top: 25230-N3000 - should be Defrost relay top right: - Horn Relay Left: - Interval relay Bottom front: 25230-89914 ? Online says interval relay, diagram says AC relay, but mine didn't have factory AC Bottom right (back): Cat hold relay (not shown) Top middle (back): 28911-89910 Seat Belt Buzzer? Interval relay wiring doesn't match the schematic - shows 10 connections but - on…

I’ve been meaning to fix my silent horn since I bought the car but it’s just been sitting in the corner of the garage bugging me. So I dropped it into some lemon juice and salt mix before we went camping for a week. I love this method of de-rusting: cheap and gentle but it gets into all the places I can’t with a brush! This is the before photos (well after a couple of hours of soaking when I realised I hadn’t done a “before”) Then when we got back, I fished this out (pic is after a rub down with micro fibre cloth to remove residues etc) - I love the fact that even the paint has been stripped off and you can read the original stamping on the back: Now …

I'm installing a 4psi electric fuel pump for triple Webers and am going with Ford inertia switch, in the past when I have done this I have always used the switch to kill the positive side but now I'm wondering if there aren't some benefits to killing the negative side instead. The neg lead is isolated from the metal housing. Any thoughts?

So it has been very common for me to "upgrade" Z head lights using CIBIE H4 housings, and then stuff in either H4 halogen bulbs, or more recently, LED H4 bulbs. Save the ol' headlight switch contacts with lower current LED bulbs and maybe you don't need to add a relay harness I say. All good. Lord, but there are SO many options for LED H4 bulbs out there. Which ones to choose? There are tons of prebuilt fancy one piece LED 7" round headlights out there (thank you to the millions of classic Jeep owners), but most of them are far too modern looking for any Z restoration I'm doing. I want a classic looking lens, then jazz the innards. There is a basic issue …

I'm trying to clean out my engine compartment of unused connectors and components. The emergency override button had already been removed so I thought I could just eliminate the seatbelt interlock relay and associated plugs. No luck. The starter solenoid wouldn't activate without the relay. Is there a means of removing the relay by jumping selected wires? It really serves no purpose at this point.

Hello gang! Been about 2 years since I properly saw the Z and played with it. But being on gardening leave, I’ve finally got time again. I’m using an ATi super racing damper, which has a 70mm pulley - to reduce parasitic losses. Yay for free BHP and boo for alternator spinning at just less than half speed, not producing charge at idle revs! Most alternators do nothing of note below 1200-1400 shaft RPMs. To combat this, I had it professionally rewound to produce earlier + modified a 63mm pulley on a lathe. This reduced the issue but the voltage needle still dances at idle until about 1300rpm which I don’t like, especially as the lights dim then go bright with rising …

I’m troubleshooting my windshield washer circuit and I’m stuck: 1) The wipers work but the washer motor has not run since I got the car ~5 years ago. 2) Voltage measured between the two wires when unplugged from the washer motor reads 3.8V when the washer button is pressed. 3) At individual wires I’m getting around 12V to relative to ground (11.97V and 12.31V) when the washer button is NOT pressed. 4) On one washer motor wire I’m getting around -0.56V to ground and +3.2V to ground on the other wire when the washer button IS pressed. I’m assuming that there should be +12V going to each contact when the sprayer is not used and the…

I found a website that lists many of the old YPC connectors for sale. Here's a link to their YPC inventory: https://www.hi-1000ec.com/product-list?keyword=ypc&Submit=Search&page=1 The last item in the search is for a pin removal tool, too. The website whois shows a registration in Japan. I placed an order last night, and today I received an email with a photo of the shipping label and a photo of the parts I ordered bagged up. That certainly inspires confidence in ordering. This should help in making repairs and modifications to 260Zs and 280Zs.
