hey guys,

I left my lights on last night and this morning my battery was completly flat.. When trying to jump start it the car just clicks like crazy? any ideas how i can get it purring again?

Is there some special way to charging a skylines battery? ><

Did you try and jump start it using the terminals in the engine bay? or straight onto the battery in the boot?

I've jumped mine straight off the battery in the boot before I found out what the terminals in the engine bay were. Worked alright.

That clicking sound might be your starter motor. Are you jump starting off another car or a standalone battery?

Positive on positive. Negative on negative.

Hahaha.

I am connecting to the battery in the boot? is that where i should be connecting?

I was using my neighbours 83 ford laser to jump start ha-ha :P

Car was completely dead when i came out.. put jump leads on and i got dash lights back but when i tryed to turn it over it was clicking like a machine gun ;)

shouldn't matter where jumping from, but the points in the engine bay near the fuse box are easy to access. Make sure you have good size cables and a good connection on the clamps (this makes a massive difference). Failing that, the ford laser battery is probably crap and does not have enough cranking amps for the skyline. Call your local RACQ (not sure wat its called in WA) or find a bigger car/battery and try try again.

Make sure the laser has its engine running as well. You can try leaving the two batteries connected for a few mintues, the two batteries will try to equalize their level of charge, and the bigger skyline battery may have enough umph to crank but its not recommend to leave them connected longer than required.

The clicking sound is the starter motor using more amps than the battery can output, it starts to throw the solenoid out and turn the motor then it overloads the battery and turns off do to lack of voltage (voltage drops when you crank).

If you pop the bonnet, there's a black box on left side of the engine bay with jap writing all over it. It has a diagram of how to jump start from that box. You've got to pop the lid off to get to the terminals.

Try jumping from that one.

I was thinking the ford laser battery might be shot too, but it shouldn't matter if the laser is running while he's jump starting. The volts/amps should be boosted by the alternator. Revving the laser while jump starting can help with this.

Okay cheers guys, i thought there might have been something more to it.. like since 100 cars ive jumped start first time i thought cause its an import and the battery is in the boot there might have been a different way of starting it.. so yeah i got a battery charger ill take the battery out tonight and charge it over night and hopefully that should fix it ;)

While the alternator will help, I suspect a ford laser may have an alternator of like 80amps max, starter motors can draw like 400+ amps for the split second they crank, if the skyline's bat is dead flat and the ford's isn't in great condition the voltage will drop too quickly across the connection for the skyline to start. but meh getting techincal now - chuck the charger on there and it should be fine

Hahaha too true. I stand corrected ;)

+1 for the charger.

      Mistakes were made, my R34 Story

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.

      Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.

      R33 Fuel Pump & Brakes after alarm swap

      By GTSBoy · Posted

      When I said "wiring diagram", I meant the car's wiring diagram. You need to understand how and when 12V appears on certain wires/terminals, when 0V is allowed to appear on certain wires/terminals (which is the difference between supply side switching, and earth side switching), for the way that the car is supposed to work without the immobiliser. Then you start looking for those voltages in the appropriate places at the appropriate times (ie, relay terminals, ECU terminals, fuel pump terminals, at different ignition switch positions, and at times such as "immediately after switching to ON" and "say, 5-10s after switching to ON". You will find that you are not getting what you need when and where you need it, and because you understand what you need and when, from working through the wiring diagram, you can then likely work out why you're not getting it. And that will lead you to the mess that has been made of the associated wires around the immobiliser. But seriously, there is no way that we will be able to find or lead you to the fault from here. You will have to do it at the car, because it will be something f**ked up, and there are a near infinite number of ways for it to be f**ked up. The wiring diagram will give you wire colours and pin numbers and so you can do continuity testing and voltage/time probing and start to work out what is right and what is wrong. I can only close my eyes and imagine a rat's nest of wiring under the dash. You can actually see and touch it.

      So I found this: https://www.efihardware.com/temperature-sensor-voltage-calculator I didn't know what the pullup resistor is. So I thought if I used my table of known values I could estimate it by putting a value into the pullup resistor, and this should line up with the voltages I had measured. Eventually I got this table out of it by using 210ohms as the pullup resistor. 180C 0.232V - Predicted 175C 0.254V - Predicted 170C 0.278V - Predicted 165C 0.305V - Predicted 160C 0.336V - Predicted 155C 0.369V - Predicted 150C 0.407V - Predicted 145C 0.448V - Predicted 140C 0.494V - Predicted 135C 0.545V - Predicted 130C 0.603V - Predicted 125C 0.668V - Predicted 120C 0.740V - Predicted 115C 0.817V - Predicted 110C 0.914V - Predicted 105C 1.023V - Predicted 100C 1.15V 90C 1.42V - Predicted 85C 1.59V 80C 1.74V 75C 1.94V 70C 2.10V 65C 2.33V 60C 2.56V 58C 2.68V 57C 2.70V 56C 2.74V 55C 2.78V 54C 2.80V 50C 2.98V 49C 3.06V 47C 3.18V 45C 3.23V 43C 3.36V 40C 3.51V 37C 3.67V 35C 3.75V 30C 4.00V As before, the formula in HPTuners is here: https://www.hptuners.com/documentation/files/VCM-Scanner/Content/vcm_scanner/defining_a_transform.htm?Highlight=defining a transform Specifically: In my case I used 50C and 150C, given the sensor is supposedly for that. Input 1 = 2.98V Output 1 = 50C Input 2 = 0.407V Output 2 = 150C (0.407-2.98) / (150-50) -2.573/100 = -0.02573 2.98/-0.02573 + 47.045 = 50 So the corresponding formula should be: (Input / -0.02573) + 47.045 = Output.   If someone can confirm my math it'd be great. Supposedly you can pick any two pairs of the data to make this formula.
