I brought my Skyline out as usual. I didn't drive it for three days after. I then tried starting it but nothing ...click click click(may have had lights on). So I jump started the bitch and took it for a spin around the block for about 20- 30 mins . I turn the engine off and then tried starting up again, n it did no probs.

Next morning I try starting it up and NOTHING :cheers: WHY OH WHY!!!? The thing is, I changed a new battery and re-con the alternator a couple of months back. Any suggestions?

1) speak better english.

2) if you have let a lead-acid battery stay in a discharged (flat) state for more than a few hours it has sulfated and will never hold a charge again.

Replace your battery. Three days of being flat means the battery is stuffed.

/thread

please get an omnimeter and measure the voltage directly from your battery terminals and post that first.

it does sound like a sulphated battery, but it could also be a corroded or degraded wire where they connect to the connectors onto the battery, since the factory don't solder the connections, they just clamp them.

get the battery shop to run some tests on your alternator and battery function.

If the battery is bad and you measure the voltage while the alternator is running and the voltage is up aqround 14V instead of 13.5V it indicates your battery needs replacing.

Battery conditioner will usually fix a reasonably new battery

If your car is not going flat after starting it a few times or your lights etc. dont dim as you increase the load on the circuit then its not your alternator i.e. regulator, brushes, windings etc. 14v is within the normal op range I thought?

There may be a current drain coming from somewhere else which will require you to look around the car with a multimeter to find the short. Not sure why you would measure voltage with an ohmeter (only measures resistance) unless you mean a multimeter which does the lot.

That click is the horn relay. If your horn isnt working it may be associated with that. Check to make sure the horn is actually plugged in and that the correct size fuse is being used. If its already plugged in, un plug it (tape the wires so dont touch car) and see if it happens again...

Thanks I was looking for the word "multimeter" could only think of "omnimeter" meaning meters everything: I was not reffering to "ohmmeter". Guess I could have used voltmeter.

HaZ3inSKY if you want help please get that reading direct from the battery terminals with the car switched off.

check for poor earth or an earth leak. Had one on my boat and used my 2week old battery as a sinker cause it would not hold charge after that

You pretty much got your answer @ post 2

Unless it was a deep-cycle battery it's probably cactus, could try getting a little more life out of it with some battery conditioner to de-sulphate the lead plates, but generally it will never be the same as a new one.

I had the same problem a while back when my sister borrowed my car for a day to work. When she came back, she didn't switch off the fog light. After 2-days i wanted to drive the car and when i put the key into the ignition barrel and turned, nothing happened. Not even a clicking sound. Saw the fog light switch still on so i decided to jumper the car with my mum's corolla. Took a while too. Crank it like 4times before it will start. Took it for a spin on the highway for an hour and the battery was fully charged. Reads 14v on my Blitz FATT.

Another note, my friend's car will never start after he parks it overnight. Reason is that the charging light comes on eveytime he switched the engine off hence battery power is draining when the car has no power. It was a faulty alternator in the end.

    • Thanks! Will get it looked at before winter 🥶 other than that she's a mint ride love it aye 
    • FWIW a lot of the local owners that do a big build tend to have cars that are perpetually broken. 
    • I just got this system but haven’t installed yet I got a Moroso sealed box (defect reasons) which will be set up same as their pic The quality is high grade, the correspondence I had with the owner (former head designer for Rockford Fosgate) was unbelievable, guiding me with what I needed. Even told me not to buy some things as it could be sorted in a different way at his loss. Just a bit of a bite with the exchange rate and don’t purchase gear in 1 hit that goes over $1,000 au, lol I forgot!  
    • Thanks mate for that reply. Very helpful.    it’s a 2022 400R so would most likely lose those features as you say.     I did a quick compare of a rv37 nav and heading for sale in Japan to q50 model. I’ll pop pics below. Seems  Japan spec head into top, nav unit second below it   below pic Q50 aud delivered     differences seem to be Aus delivered has a different plug top left hand side of head unit- not sure what and where it goes.   and nav unit Japanese tv37 had an extra plug put    Again I’m really not sure what each of these differences mean!       the actual plugs on a v37 and q50 screens look identical on both screens… pics below for comparing. (One screen was is a us delivered one) but should be same gps signals etc as Australia.    If it were as simple as swapping a nav unit from q50 aud delivered im interested -just want to figure out what the missing plug is for before spending big $ on a second hand part for it to not work, and I guess with the head unit, if the band expander does the job (I got a 20mHz so should get the range I’m after) so should narrow my issue down to nav unit only.  I’d love to know what the extra cable on rv37 does and if I eliminate that part what it’ll do to the setup,    and also, if I can figure out what that head unit plug difference is, what does that cable do and where does it got can it be altered or re-plugged?! Excuse my ignorance what is ACP/AA, what does that stand for? (Apple car play? Android air play)? so If I swapped head units to save using a band expander, I’d likely lose those better features to have an oem Unit operational. Better to use a band expander and retain AirPlay options and newer version of head unit     provably best to band expand it, and focus on the nav unit. th isn’t  a big deal/ would be cool to have it working  from what I can tel we use a PAL Signal and Japan uses a NTSC signal  I don’t know if there’s a co better or if the screen only reads NTSC, or if it’s the tv module that needs replacing… no big deal don’t need it but more of a curiosity thing on that!   Thanks for the info re tyre sensors, helpful and great to know.  I was reading the online manual off Japan website and it seemed to make it sound more confusing than it is  I guess a rim replacement would require the sensors to be moved to a new rim to carry that option over?!     Thanks for the info regarding diagnostic mode. I appreciate your help mate. Trying to brainstorm here to find a solution to get as much gadgets as I can working! I plan to get my local Nissan tech to have a look too who used to be at an Infiniti dealer back in the day to see if any thing they have or idea can find a soliton. But hoping anyone here has gone down the same route to make life easier!!   i guess identifying the cable/plug differences and what they do would be a great way of finding out if the units are transferable    thanks again 
    • No idea about the remote start part. If the V37 nav is anything like other Nissan JDM vehicles, you can't get the factory Japanese nav working in australia, a card from a different car almost certainly won't work, those cards are usually matched to the serial number of the DCU.  You could be possibly swap out the components from a AuDM Q50 to get it working, but if this is a new model (2021+) 400R, then you will lose the newer features like ACP/AA.  That said, if you have ACP/AA, just use google maps.. I assume a band expander would be required to get the local radio stations, but don't forget the Japanese FM band is narrower than ours, so you still might not be able to receive all Australian stations. I can't see any reason the tyre pressure sensors won't work here, there is the sensor unit inside the rim and the receiver nearby in the wheel well.  I have never had to change the batteries on my 2015 Q50, so I assume they last quite a while.  A straight battery change shouldn't need them to be re-registered as they are the same unit, that should only be required if you replace a sensor with a new one.   Word of warning, if you ever go into the 'secret' diagnostics mode on the main screen, DO NOT EVER do a 'reset' in this menu, it will erase all of your model specific data in the DCU and you will need a trip to a dealer to re-program it all, which would be particularly painful being an import.  This applies to the AuDM Q50 too.
