I was in a hobby shop looking for Lionel train bulbs with the same base as the Z car gauge bulbs (BA9S) when I saw an LED display (display of bulbs). I ended up buying a package and building an LED gauge bulb. Unfortunately, LEDs have a very directional output and the gauges are designed for the all-around glow of an incandescent bulb, so the brightness did not make its way to where it needed to be when installed in a gauge. It was still fun though and I can see why people get hooked on LEDs once they try a few. I couldn't get a good illumination picture in a spare tachometer I have. Too much glare off the face of the gauge. I did find that the LED turned a turn sign…

Could someone tell me where the wiring harness should be located in the interior passenger side. From the firewall to the hole behind the seat. Does it lay against the rocker panel? Does it go under the seat? Does the emergency brake wire go behind the seat? 71Z Thank you very much, TimsZ

I’m in need of some guidance in isolating an electrical problem. Here are the symptoms: I started the car yesterday and kept an eye on the gauges as it warmed up. I noticed the ammeter was not moving to charge as it usually does – it was holding dead center or perhaps a very slight discharge at all revs. I flicked the turn signals and got a small discharge with each cycle, no change at revs. I turned on the headlights and saw no movement on the ammeter (no discharge), no change with revs. I drove the car a bit to see if anything would break loose and begin operating normally, no joy. Here is some background info: the car came off a full resto two years ago. It …

I've made a serious effort making sure EVERYTHING works on my Z as it originally did. My first question is about the annoying buzzer that activates when I open the driver door. When I open the driver door, the buzzer goes on and the overhead light goes on. It doesn't matter if the key is in the ignition or not. It buzzes either way. Is it only supposed to buzz if the key is in the ignition? Question 2 is that the passenger door only activates the overhead light when opened. That's correct, right? Once I get this ironed out I should have everything functioning 100%! Yes the original clock works too. Thanks.

Ok, so I decided to replace the key cylinder.. Wanting a new set of keys i could than get my locks rekeyed for. I went with an locksmart key cylinder that I got from autozone. I had to do some altering to the part (mainly trimming the pivot point to reach the full rotation that the original had). I got everything back together the best of my knowledge. I havent slapped it in the car yet. My question is the switch here.. Right now it seems to be a closed circuit.. does that look about right? Is it suppose to move open?

Hi there, I've been having a multitude of issues with my 71 240Z lately. The issues have included: Lack of spark when starting (starter motor turning) Not even turning over when starting Engine cutting out immediately after starting Engine cutting out/dying as I'm driving down the street and most recently buzzing when the driver door is opened (although no key is in the ignition - However inserting the key stopped the buzzing) I noticed that the parking brake light would sometimes be illuminated when the brake was engaged and sometimes not. A little jiggling of the key would cause the light to come on... hence my suspicion that the switch may be worn. A couple questi…

Hi all, Could you please help me with fixing my tachometer issue? I have 240z 1973 us version. The tachometer seams working on the first look properly. But it doesn't because it displays only +- half of real rpm. Tachometer can't go over 3000 rpm but the real rpm is on limit. I checked the coil and resistor and boths are ok. I have red coil 1.5ohm and the resistor is 1.8ohm. Thank you for any suggestions how to fix this issue. Thanks a lot. Kind regards, Radim

There are two blue wires coming out of the harness behind the heater control panel. Both have in-line glass fuses. Both are not hot and not attached to anything. What are these for?

I am restoring my 1/70 240 and my wiring harness has a 5 pin connector with a separate lead that connects to a condenser. All of the replacement voltage regulators available have a 6 pin connector and no supplier seems to know for sure if it is a plug and play fit for my setup. At one point I'm sure I replaced the original regulator but the car was completely disassembled for a "frame off" resto several years ago and the shop misplaced my regulator so i'm going from scratch here. Any advice ? Thanks Brian

How do I identify a replacement lig ht bulb for the engine bay trouble light? The bulb in the one I have says Toshiba A12V8W on it meaning 8 watts but when I got a spare at the auto pa rts store the new one wasn't as bright. I compared current draw and the original 8W bulb is showing just over .5A while the new one is at .12A. Both pictures are of the original light bulb: The "posts" that stick out the sides are in line with each other. I have seen bulbs where the posts are offset but not on this bulb.

I have a 1971 240Z and earlier this summer I had a major electrical fire. Something happened and the main wiring harness in the dash melted. I have had this car for 6 years and plan to have it another 30 years so I am more interested in fixing it once and correctly. Are there any companies that will remake a wiring harness? I am also thinking if I am going to upgrade the wiring harness I might as well upgrade the gauges since this is more modified than original. Anyone have any ideas? There is an auto electrician here in Portland, Oregon but it is a minimum of $1,500 up to $3,000 depending on what he finds and I am thinking if I can get all new parts and then have so…
