I am working on installing a set of Speed Hut gauges in my 240z (my "track car"). Manufactured in 12/70, the wiring for the tach doesn't match the wiring diagrams I see online. Other than power and ground and illumination wires, the Speed Hut tachometer has a single yellow wire that is supposed to be hooked up to the "coil -". It seems to me, after looking at the stock wiring, I have to not only figure out which wire is "coil -", but I think I may have to connect some of the other stock wires together in order to "bypass" the stock tach. Color legend is: blue = L yellow = Y Black = B Red = R White = W Green = G Ignoring the wires for gauge illumination, I am looking specifically at a 4 prong connector for the stock tach. Here is what I am looking at... on the left are four wires from the harness that are in the 4 prong connector, and on the right are the four wires coming from the tach that are in the 4 prong connector: Harness wiring Description Connection Tachometer wiring Description RL red with blue stripe ---- YR yellow with red stripe GW green with white stripe ---- W white (with black band on it) B black ---- B black BW black with white stripe ---- W white (with red band on it) Additionally, I am running a Crane HI6 (multiple spark discharge) ignition which also has tachometer adapter hooked into the circuit. The ignition and adapter were previously in use and worked perfectly with the stock tach. The wiring for the ignition and adapter has been untouched since the car ran. What I need help with: Which wire is the negative from the coil? Which, if any, wires do I have to jumper together with the stock tachometer no longer in place? My guesses are: Black - connect the Speed Hut yellow wire to the black wire in the 4 prong connector Connect (jump) the green with white stripe wire and the black with white strip wire (to bypass the stock tachometer) But, I am not sure. And don't know what to do with the last of the four wires (red with blue stripe at the four prong connector).

Thanks for the replies...... I did let the battery charge overnight, and it is reading 12.8V with the meter. Tested it with my harbor freight battery tester, and it tested at 750 cold cranking amps. I pulled the Diode plug and tested it with a meter, it looks correct, shorted on the two pins, and diode tested fine on the other two pins. It does look a little melted on the top of the white plastic top... When I start up the car, and at different revs.......the battery voltage stays constant, so thinking no output on the alternator. I might yank the alternator out tonight and take it to Auto Zone and have it tested.........IF it's bad, I wonder how Motorsport Auto will deal with the warranty, it there is one......... So, do you guys go looking for a new alternator or roll the dice with a rebuilt one?

Planning to swap an R200 into my Series 1 car (12/70 build date) and am looking for the mustache bar, front diff mount and insulator and the rear transverse link mount from a later 280Z that came with the R200.

Awe man this is a trap!

Agree with Yarb on rebuilt alternators. I make the store test them before I buy one. Been burnt before with a bad one, literally. Popped all my fuses as soon as I cranked the car. If you have a volt meter or can borrow one, check the fully charged battery without the trickle charger. Mine usually reads about 12.5 volts. Then crank the car and see what the alternator is adding, should go up to 13.5-ish. Check the alternator belt to make sure it's good and tight. I always use a broom stick or similar as a pry bar to get mine tight.

Here's an old thread about a similar problem. (Edit - man, I wrote a lot of stuff back then.)

Good opportunity to learn how to use a multimeter. Check voltage at idle and while raising RPM. Some of the conversion plugs from MSA have been known to melt and fail. You can get a cheap meter for cheap at a place like Harbor Freight. https://www.harborfreight.com/7-Function-Digital-Multimeter-59434.html

Everyone on this forum I believe has had issues with rebuilt alternators and starters. Take it to the parts store and have it checked out.

S30 parts are rare and expensive. Not enough competition or volume of sales to keep the price down.

that makes sense

Or a new flare on that tube and maybe a new flare nut. I'd venture a guess that it didn't go 6 years without any leak at all - probably just one that was slight and unnoticed... (just like many plumbing leaks)

This is the other name and email used during the email communications with Sully. Phaedra Rosengarth armychick44@hotmail.com He sent several pictures of the new tank and a few pictures of a partially restored tank that he allegedly was working on.

A quick google search... it's not good. EDIT: not trying to be a prick but the New Zealand girlfriend is online or in person? The email in question is sully38b@gmail.com. Sooooo if you get a message with that email or similar messages beware. I'd ask the moderators to ban PiersMorg18 (have already reached out to Valk and provided picture evidence). Sad what people have to resort to! Not today scammer, not today!

@Mike

What were the other two options other than zell? I got scammed once, but thankfully I used PP and (it took some time, but) I was able to get my money back.

@Mike Might want to have a look here.

So, earlier this year I replaced my alternator and diode from the Z store ( 240z Alternator Upgrade with internal voltage regulator) I have been driving it on and off all summer and fall. Today I took the car for a drive in a light rain, with the wipers and headlights on and made a couple stops in town, started no issues. Drove home about 20 miles and got to my driveway and turned off the car so I could put it in the garage, but left the lights on. Went inside and grabbed a set of keys, came out and the car would not start. I had to jump it..... I did noticed the blinkers were slow when I was coming home,,,,,,, The AGM battery tested fine a few months ago and it's "sits" with a trickle charger on it....... Thinking the Alternator might of went? Battery went bad ( it is 3 years old)? Before I dive into it, I thought I would ask for advice..... It seems odd that the rebuilt alternator from the z store would have gone bad? Before I pull it and have it tested, has anyone had issues with rebuilt alternators? Any advice is appreciated.......
