Is there a how-to for a wiper motor rebuild for the 280Z? I have mine out of the car, and out of the bag. Even though it's almost 30 years old, the motor case is still nice and shiny, but I don't think I want to go inside unless I know what is there. thxZ

I have a 1972 240z and the heater blower switch does not have 12v from the plug under the dash. My 240z chassis electrical schematic does not show a heater switch or wiring. Maybe I missed it. Where does this circuit get its power? Thanks Bob M

I just got this car and it has nothing running the rear lights. I was wondering if there is an aftermarket kit I can buy to hook all that up again. I don't drive it now because I really don't want someone to rearend me. The headlights are ghetto-rigged to a switch and are pretty dim too, but at least they come on. I was thinking a painless kit might work, but it seems like a handful to wire up. Any experience is greatly appreciated. Thanks, Jake

Hey, I'm looking to install a cut-off switch in my '70 Z. There's already a hidden button with wiring running out through the firewall and ending at the battery (though it's not connected). I understand my fuel pump is mechanical, so I'll probably have to go with an ignition cut-off, right? Any help would be greatly appreciated!

I was driving my '78 280z home yesterday, and the turn signals stopped working. When i hit the signal switch or the hazard switch, nothing happens, no noise, dash lights, or exterior lights. I bought a turn signal flasher, but I can't find where the old one is (how embarrassing). Is this the problem, or could it be something else? Thanks, -Ben

Hi all. I removed the dealer installed am-fm radio from my car. It was a Bowman radio that had a special metal plate the mirrored the size of the original am radio faceplate. It also had a hole for the electric antenna cut in it. I have attached a picture for those interested.

I'm working on fixing my tach since it's not working because of Mallory ignition system (car is 72 240z with L28, mallory ignition, 3x Weber). I've also got the tach adapter. The tach adapter is plugged between the green distributor wire (Dist. Trigger?) and red wire (coming from the ignition - 12V when key is on "on" position). I've tried first without bypassing the ballast resistor. Tach was working only when key was on "Start" position. Then, I've tried to bypass the resistor, the tach is now working as it should .... but the engine does not run properlly anymore: misfire, smoke like crazy (white smoke), stalls if i release the gas pedal (even with the choke on) an…

Is it possible to bypass the electronic controller for the windshield wiper motor? I had the idea that maybe the controller (a transistorized thing) itself is pooped-out, so that might be the reason why the motor is slow. If you could do a quick check, then you could narrow things down. The controller doesn't seem to be available new. thxZ

Hi all, I have a 1973 (build date 6/73). I am refreshing the cooling system and found the thermostat cover is a bit corroded (see pics #2&3). It appears that a cover for this build date is NLA. My question is what is this electrical part (see pic #1)? It appears to be a thermo control of some kind and it fits in this cover w/ pipe threads (see pic #2). It is not the water temp sender as that is in the thermostat housing itself. The only thing I have discovered is that it might be a thermo controller for the automatic transmission, however I have a manual transmission. As far as I know it never had an auto trans. The real question is: Can I use a thermostat cover from…

I have two problems with the electrical system. The first has to do with the turn signals. When I turn the switch one way, both lights blink. Only one turn signal is illuminted in the dash though. I'm lost here... The other thing is the tach. When I turn the key on it pegs high and stays there. 73 240z Any suggestions? Rich

As my tittle says I'm not able to find the tach wires into the engine bay of my 72 240z. The previous owner installed a mallory ignition system (Mallory Unilite distributor + Mallory Hyfire 6AL ignition) but did not take care of the tach wire. The wire I'm looking for should be a black and white wire which should have been plugged to the coil when the car was stock. On the following wiring diagram, we can see which wire I'm talking about I doubt the previous owner cut or removed the wire when he did the swap. Where does this cable go???? I've tried to see if I can find this wire by following the harness from the cabin with no luck. Where should this wire be? Can so…

I've had my Autometer autogage 5" tach in the dash for the past couple of months and have had this issue since i installed it. the tach has an intermittant problem under 2K rpm. it usually jumps around between idle and 3K anytime i'm under 2K. i've dealt with it though since i am rarely under 2K rpm. i thought that it was normal for an aftermarket tach, but then i installed a 3 3/4 sunpro in the wife's 510 and it works flawlessly. the reason i installed this tach in the first place was because the stock tach would only rev to around 3K rpm... very odd. i attributed it to the fact that it has a 280ZX electronic dizzy in it. anyway, what could be causing this? is it possibl…
