   my early 280z uses the ammeter which I prefer to a voltmeter, anyway the problem is its not center when no current is being drawn. I was wondering if anyone knows off hand if there is a centering adjustment mechanical I would presume.

   Hello everyone, i have a turn signal problem driving me mad. Only thing left is that it´s the EU spec taillights. Plugs are fitting but no turnsignal. Tested switch, relay, fuse, Harzad switch.... Only that the hazard switch is from another year (other plug in 77 than 75). So far I think its wired in correctly though. So, anybody did a Eu taillight conversion and can explain to me what to change how? thanks a million, Richard

   Wiring a Driving Lamp Relay 1 2

   Hello! I am installing some driving lamps, and I will use a relay. I can wire the relay directly to a switch, but common sense (state laws) tell you that driving lamps are only supposed to come on with the high beams. So I have a 12V feed from the ACC circuit on the fuse panel to the relay, and I wanted to wire the relay's ground to the high-beam (ground) wire so the driving lamps come on with the high beams, because the high beam switch goes to ground, right? Attached is a simple schematic. BTW- It's a 1978, so the High beam wire is a RW wire, according to the FSM I atached a simple diagram

   Hello, my 1972 240z won't display the temp, I grounded the wire that goes to the temp sender and it does not move the gauge so I think that rules out a bad sender, what can I do to find the problem?

    What is the box in the middle of the photo. LHS against firewall. It connects up to the clock (not working) and makes a humming noise whenever the battery is connected. Note car is a 73 JDM Fairlady Z / RHD. I know the unit on the left is the Flasher relay.

    SO I have 1 horn working now (adjustment screw) but the second horn would not work. I took it apart and it has a set of points in it. So I adjusted the screw all the way in but cannot get the points to separate. Are the points supposed to have some separation?

    I have the gear reduction starter and all was well for about 1 month after taking the car back. -One day the battery would not turn the starter over and I was at 4 volts. Battery was new and needed charge for 3 days which is alot for this type of battery. -Load tested ok. -I made a hard start relay 30/40 amp relay. -The car will not turn over w/o the hard start relay. -When the car does turn over the starter is still turning over for a couple seconds, most of the time. It doesn't happen every time. -Starter is new? -II also have the MSA upgrade alt/diode. I have 14.2 volts at idle. -Is that too high? Thanks, GI

    I don't know much about electrical systems, so this might be a really simple issue for some of you but it has me scratching my head. And it caused my son to get pulled over, which resulted in a 3x fix-it ticket for 1) The brake light, 2) modified exhaust and 3) no front plate. Here's the issue: Right side brake light doesn't work. Some issues: - Left side works fine - Replaced the bulb. No change. - Realized that the same bulb is used for turn signal and it works performing that duty! - Hazard lights (including the brake light bulbs) are working fine. - It worked until recently - I will go through the fuses tomorrow when it's light, but I assume…
