I have a 72 with the original wiper motor in there. When it is switched on, the little box that is clamped to the side of the motor clicks, but nothing happens. So, I bought a used motor and it does the exact same thing. Does anyone know where to begin troubleshooting? What exactly is that little box?

A friend gave me a 78 280Z that needs some TLC. All seems well but needs some fixing up. He said it will run but needs a fuel pump relay. He had it hardwired to make it run, but has sat for about 2 years since he ran it last. He gave me 2 starters and both have shorted silinoids (sp). The hot wire coming from the battery to the siliniod is shorted to the chassis ground-- I've tested it with a meter. When ever the battery is hooked up, the started starts turning the engine over. There is some Jerry rigging on the wiring harness by the front passenger strut tower, just rear of the AC tank. This is on some white wires approx 10ga. If you have any idea what I'm talki…

Hey guys, I got myself a power antenna about a year ago, and it just decided to bite the bullet. Whenever I turn on the stereo, the antena makes one "click" type noise, but the motor does not run to push the antenna up. Same when i turn the stereo off. I'm tired of the extra hassle. I'm wondering if it's possible to get a stubby short rubber covered antenna like those seen on the 350Z or S2000 and use it on an early Z. I'm going to the Nissan dealership today to see if they can order an antenna, but if you guys know a little more than me, please let me know. However, I haven't seen anyone with that style of antenna on this forum yet, so, I might actually be the first to …

Hi all Have an early 260z and I'm rebuilding a stock intake manifold for it. Hit a snag when it come to the wire leads from the Throttle Opener Control Valve (BY wire not seen in picture) and EGR Control Valve (GY wire seen in picture - yellow arrows) were do they connect to and and what kind of connector is on the raditator side if any. I have a partial wire lead but the radiator side has be chopped. Pictures would be a big help. Thanks Jim 1974 260Z - RLS30-020697 (01/74) Note: Picture is not of my 260 just for illustration purposes. Picture file to big Will upload as soon as I can. Throttle Opener CV and EGR CV wire 2.bmp

Little did I ever realize that my initial thread would grow to 5 pages! Member involvement is what it is all about! There has been some talk about 'improving' the original wiring and since the subject has come up I've been giving it some additional thought. I agree that there could be some improvements to the wiring harness, but to what extent? Simple changes, like additional grounds, better wire, fewer contacts/resistance points, new fuse boxes (using automotive blade fuses)...etc., are easy enough to accomplish. They would require little (if any) modifications necessary on the part of the installer/purchaser. That was, and still is, my goal for this project. Other…

hi everyone, i have seen this problem mentioned before where people have a problem where when their car is at idle the electronics dont work. i have this problem aswell, that things dont run off the batteries (e.g. headlights wont turn on again unless you turn off the ignition, blinkers dont blink etc etc...). i wanted to know if there is anyway to fix this without having to do a major car overhaul, i mean is it simply an issue of contacts or is it more complicated? i also have an odd problem where if i push the "Pass" button before the headlights change to high-beam (which takes forever) my "Shift light" on the steering column (after market part) lights up. i'll have to …

I was driving my 72 240z home yesterday when my tach dropped to zero as did the fuel tank , temp, and oil pressure gauges. Turn signals also packed it in at the same time. I also think that the car started running a little more rough (but maybe that was my imagination as I was peeved at the elect system) Now the car won't start!. Any help in troubleshooting this one would be greatly appreciated

I am new to the forum and made another post in the tech area and find out now after "wading" around that I put it in the wrong forum. I have an 83ZX that had an intermittant starting problem (having to turn the key more than once to get it to start) to now not starting at all. All I get is what sounds like a relay click from the inside on the passenger side of the car. The dash lights dim, but the interior lights and low oil pressue light do not. The battery and Starter have both been bench/load tested and are good. I have 12 volts to the large terminal from the battery to the starter, and the ignition side of the distributor in the "on" position. I do not have any volt…

I have an EFI setup with a electronic distrbutor. Im not getting any spark from the coil, There is power going right through the primary circuit (in and out of the coil), but no spark. Could it be a problem in the distributor? Im not too familiar with electronic distributors, so not sure what oculd be wrong. I did notice that the reluctor point and the pickups are not evenly spaced i.e its as if the shaft with the reluctor points has been shifted off centre to one side and as the reluctors spin around they run closer to the pickups on one side. Could this be the reason why the coil is not creating spark...any ideas of what I can test ? Cheers Ray EIDT: the whole system w…
