Replying to: cannondalege (May 26, 2009 7:51 am) What Year is your Z? I found that hot from battery is red, white smaller wire, Ibelieve leading to the alternator, is white (about 10 gauge). In my Z it loops about the battery and down to the alternater. When I examined this single wire (harness) and the insulation was cracked and I solve my battery drain problem. Maybe your probem is just that?

Replying to: cordliz (May 21, 2009 1:07 pm) Hope Majix solved the problem for you? In the first few and maybe years after of manufactured Z's there is a tip sensor in gas tank. This sensor will cut all power to the Z and there is a sensor that will cut all power if the car occurs in a crashwhen fuel could leak to avoid fire. This light seems that it isn't related, but if after you turn your Z off the injector cooling fan runs, the gas light stay on it might not be the fault. Just FYI I'd thought I could help! Finally could you mail me back on the conditioner problem, Did it just take a recharge or What to fix?
#17 of 24 Re: checking trouble codes [rocs1] by pauld5 May 26, 2009 (12:13 pm)
Replying to: rocs1 (May 21, 2009 2:06 pm) I believe that the vehicle has a diagnostic cord and if this is the case some part supply chain in my area rent the meter for troubleshooting. $150.00 Returnable deposit and $6.00 a day rental. Follow the sales peron's advice, and I have read that the conector is below or around the hood release area by the steering wheel. Check that the device will couple, and the trouble code will be in the book along with renting the device? If not check out the right kicker panel (much more work) passenger seat and if you have a ECU similar to the pictures that are for prior years? Turn the screw at the top of the ECU engine off counter, clockwise, turn ingition on (without starting), with ig on turn the screw all the way clockwise and read the lights (number of blinks) It should give you a number but, if it just gives you 23 and 31 over and over check the ECU. The screw should have complete stops CC and CW, if not find another ECU and scab the reostat (replace).

Replying to: cordliz (May 21, 2009 8:00 pm) Are you sure the letter aren't CAS (Crash assisted safety) device? Do you have air bags? I'm Serious, There isn't anything that would tell us how to verify charge on a coolant system, "That I know of!"
#19 of 24 Starter Relay by cannondalege Jun 03, 2009 (6:43 am)
Oh well, the dealer took me to the showers again. 4 hours of labor to diagnose a faulty starter relay. It's amazing that they can get away with things like that! The ignition system wiring diagram doesn't look like it would take more than a couple of hours to check everything. Had I known it would be 4 hours, I would have tried myself. But I thought I'd get some value from their "expertise". Wrong again!

Replying to: cannondalege (May 26, 2009 7:51 am) What was the problem? Did you figure anything out on the problem? Charging System, Battery Terminals, Fail Safe Mode, or? When I had Emission part problems the running lights didn't work, clicking in the engine compartment after the key was off, and brake lights stay on after turning the key off! Now I think I have a problem the sensor light on the dash lit, so I am back to the diognostic sheet for troubleshooting. I am changing out the leads to the battery.

Replying to: z32chic (Aug 05, 2009 11:35 am) to the left of the steering column is a dash brightness adjustment switch. See if that works, if not, then the harness might be loose. Replies to this message: z32chic (Aug 07, 2009 6:28 pm)

Replying to: pauld5 (Aug 05, 2009 3:36 pm) harness might be loose....... where would that be....... behind the steering column?? Maybe I just might look around to see if anything is loose.   thanks pauld5 for the reply
#24 of 24 86 300ZX Reverse Light Problem by ost86300zx Nov 27, 2009 (9:10 am)
My reverse lights stay on all of the time. Could it be a switch on the tranny or a switch on the foot pedals, eletrical. Any suggestions would be helpful. The car is a 5 speed manual. OST
