Guy's - installed MSD (6425) ignition over the w/e & now get pinging on my 240Z ! dropped the timing a few degrees ..now only @ 13/28deg & no change in condition. Using a 280zx dizzy, E12-80 module now removed with vacuum disabled. the MSD should not have messed with the dizzy adv curve so not sure why this should have happened. no change in gas quality - same gas in tank before/after swop. Motor is a 2.8L / mild cam ~ 10:1 CR Any comments/observations ?. thanks

Hazard switch and turn signals work fine, but when I step on the brakes only the diverside rear light comes on, with the ignition turned off and my foot still on the brake if I push the turn signal arm down to the left the driverside brake light turns off and the passenger side brake light turns on. After reviewing SteveJ's fantastic Turn signal Analysis, Hazard Switch ? Brake Light ? Turn Signal Circuit Analysis | Fiddling With Z Cars I'm thinking there might be something screwy going on with the T/S switch. Just wondering what you guys think before I open the switch up? Thanks, Chris

As per This thread I am going to buy a new ZX matchbox ICU and hope that solves my problem, I want to know if anyone knows what brand I should buy to avoid having the same problem as last time, is there only one company that makes them and everyone else distributes them, or what, there is Back Arney, WD Express, Standard motor products, etc.

I'm having problems with my ignition lock cylinder and need to turn to you guys for help. Original symptoms, key was stuck in ignition in the ON position so it wouldn't turn to START, or back to OFF. I read on here to spray in some lube, wiggle the key, rap on it with a hammer (this is a bad idea, by the way - will explain later), all without luck. So I pulled the assembly (pictured below) off the steering column and took it to a locksmith. He found that there's a stop inside the lock to keep the key at the right depth. Mine was cracked (possibly made worse by me hitting the key with a hammer) and hence it was very easy to insert the key slightly too far, at which p…

When I hit the horn I can hear the relay click and a little chirp from the horns, if I keep the horn switch down there is no sound from the horns then it blows the 10amp fuse in about 4 seconds. I have jumpered power from the battery to the aftermarket horns and they honk loudly so I know they work and are grounded. There is continuity between the green horn wire and the H terminal on the relay, as well as continuity between the S terminal on the relay and the horn contact switch. There is 12v at the B terminal on the relay, all is as it should be except this short that is happening. Not sure how to proceed, Thanks, Chris

Hi guys, I just acquired a '78 280Z and the wiring is in pretty poor condition. It looks like some has frayed and some has been disconnected or bypassed by the previous owner. I do have the FSM and have looked through the electrical section but these items have both ends cut so I can't trace them. Can someone help me identify the two items circled in red? 1) This part is in the driver's side of the engine bay next to the ignition coil. Both ends frayed off. 2) These two wires are coming through the firewall near the battery. One is gold and the other is white. The PO has them taped to two other wires that have been cut. No clue what they should be going to. …

This is not a daily driver and use it only when one of the other cars needs to be serviced, so it sit most of the time. I have a few things that have stopped working, the wipers, radio and fan motor. I have checked the vacuum lines and fuses and all are ok. i am not sure where to start looking for the problem

When my car sits out in the sun for too long, it will crank but not fire, I hooked up a timing light and it would not flash so I know it is a lack of spark, Ignition coil is new, distributor and alternator are both new upgrades/swap (new 280zx parts wired in) so the ignition module and voltage regulators are both good, when the car cools down (the interior) it will start just fine. Any Ideas? (My only guess is a random separating connection or dieing ECU) 76 280z

Higuys, ox I was at the JY getting an Altima relay box, and I noticed that the battery cables didn't have the usual thick lead battery post clamps. It had a kind of round strap. Further, the one I saw had a knurled nut and a kind of a black plastic quick-release handle! I thought it was really cool looking and would be nice if you remove your battery every fall (no more stripped clamps and no wrench needed.) Both of the clamps also had two taps for extra, smaller wires (two on the negative and two on the positive) that you could remove by pressing a release button, which would be nice for those headlamp relays, radiator fans, or what-not. The negative cable has gro…

First off, everything else electrical works on my car and the system has never been messed with at all. The only additions I've done to the car have been Dave's harness upgrades. My problem is both rear turn signals are not working. I've tried to trouble shoot them and I'm by no means a wiring guru. No luck so far. Would a bad rear chassis ground cause this? Any thoughts???

I installed a sound system in my Z this past weekend. Went with JVC head unit, 4's in the door and 6.5's in the rear. What's interesting is the subwoofer I found to give it some much needed bass. This unit will fit in your wheel well with no mods needed. Packs a good punch and comes with an amp built in the box. Kicker 11HS8 Hideaway? compact powered subwoofer: 150 watts and an 8" sub at Crutchfield.com You can lay the spare tire pressboard cover over the wheel well, and with carpet on top its nice and flat. Easy to install, only drawback is you have to get rid of the spare tire. That's more weight anyway!
