R32 Gtr Battery Issues

[The Baron]

Hello all,

my (newish <6 months) battery seems to be flat after just a week of non driving.

Any common culprits for battery drainage where I might start my enquiries??

Cheers

Battery in the alarm's siren getting old ?

obviously something is drawing down on the power. So yeah check all ancillary gear (interior lights etc..) and earthing straps.

I've experienced and heard a lot of people with R32 GTR's who cant leave their GTR sitting for a week or longer period of time. Some of the blame is the car alarm drawing down on the battery.

I did have the several small watch type batterys powering the m80 mongoose alarm drain after several years and had the siren part replaced.

(after ripping out the alarm and smashing it as it makes that orrible dull sound when going flat ....)

Buy a charger and put it on trickle charge whilst not driving it often.

Because if you just disconnect a battery lead terminal and if you have an alarm/imobiliser it will trigger the alarm !

The other thing I have found is that the spark plugs foul easily if it is idled for a while whilst stationary and then turned off, which makes it harder to start next time and drains the battery further while trying to crank over.

I like mine to start every time and on first turn of the key rather than 2-3 cranks. I drive it every other weekend so not often.

So replaced battery, alternator, starter, plugs', ignitor, fuel pump & filter

I understand that the OEM ECU detects the location of all cylinders on cranking. Some of the aftermarket ones look for the position of a particular piston (#1) being TDC so crank a few times on start-up

If your battery is tired this can be an issue.

Thanks for the feedback,

my money is on the alarm being the culprit ........

Will get it checked out, but in the meantime for <$80 buck I got myself a CTEK MX3.6 to charge the battery and then trickle charge it (my old battery charger was shite anyway......)

Boot light?

You can put a multimeter in amp mode in series with the battery (keys out of the ignition), then pull fuses to see what causes the drain measured on the multimeter to drop.

I just pull negative off the battery since the GTR is not a daily anymore.

boot light - cunning...... will check and try the multi meter as well

Thanks

It's also worth having the alternator's output checked.

They must really pump out the power and an old alternator will never quite make the full 14+volts.

GTR's need steady battery power and that means the alternator must be in top condition.

just be mindful of which scale you put your meter on. Some cheap meters which dont have fuses are only rated for so much.... or if they are fused, try not to blow them!

I'm having a similar probem, possibly due to the bottom "ring" of the battery terminal has cracked and not making good contact onto the battery post.

Called into my local Nissan dealer to suss out a new setup.

Sit down everyone -

$200

WTF?????

So I'm going to see if I can get someone to weld it shut.

Replace it with something better.
