R34 GTT Fuse Query

Hi All!

I'm replacing my battery in my R34 GTT and decided I would check to see if there was any excess drain on my battery whilst it was off.

Noticed a pull of about 630mAh. Now from what I've read most cars should only be pulling up to a maximum of 50mah.

I've identified the culprit to be one of the 60A Main Fuses as see attached.

I've been searching the internet to find out what is used by this 60A Main fuse but I have been unsuccessful so far..

If anyone has any information onto what parts of the car uses this circuit that would be great!

 

.... Whilst we're at it, does anyone know what the standard amp pull is whilst the ignition is switched on? (with no accessories connected) I suspect the main issue is that some of the battery cells (as to why I am replacing it) are dead but the battery drains completely after 5-10 minutes whilst on ignition and needs a jump start.

Attempted to download the manual but couldn't find the wiring diagram.

But furthermore I agree as I've connected the amp/subwoofer back onto the positive terminal and noticed that the drain is back down to 50mAh which is O.K

I also noticed that by doing this when I have switched the ignition on it has lowered usage from 6Ah to 1.2Ah. So I suspect the Amp/Sub cable somehow creates a better circuit which in turn is pulling less amps.

For now I'm happy with my 50mAh drain and 1.2Ah when it is on Aux/Ignition. I wasn't prepared to test parasitic drain on aux/ignition when the amp/sub was on as I suspect this will blow my fuse in the multimeter (10amp fuse)

Hi,

Good news.

FYI, current is measured in just Amps (or milliAmps).  An Amp-hour is a measure of battery capacity, being the product of a current and a length of time.  You just need to talk about Amps.

And for measuring big currents, you need a clamp meter.  Gets the meter out of the circuit and infers the current by electromagnetism.  Worth the cost at Jaycar.

      Shoota's R33 GT-R RB30/26

      Hi guys, long time no post as per usual! It's been a busy year so far, the biggest thing being a new job.  After 28 years in the automotive industry I decided it was time for a change.  I was losing faith in the industry and where it's heading.  Now in a completely different industry (electrical) working for a company that manufacture water pump contollers.  Not as sexy as cars but it's an interesting,  challenging industry. I now don't work Saturdays which is a bonus!  It's still 50-55 hours a week but having Saturdays ack after 28 years of working them is awesome!   No news on the GT-R but i did decide to add some more JDM goodness into my life....           1990 300 ZX.  She's not perfect but for a 35 year old car she ain't bad!  Just going to tidy it up a bit and enjoy it.  It's currently auto but will start stockpiling everything for a manual swap. It WILL distract me even further from the GT-R but im hoping not for too long! It somewhat proves a 6'8" freak can fit in a 300 ZX.  Sort of...  I drove it home from the previous owners house in Melbourne via Black Spur and Merton Gap (2 awesome bits of Victorian twisty road) and it was amazing!  Handles so well!!!   I don't think it would be worthy of a full build page but I'll post up some of the upgrades here if anyone is interested?  Cheers guys!

      End game is to: - Remove all the slop from old worn parts - Adjust setup so that the wheels actually fit and the car is drivable (currently it is not because of the extreme rubbing on the guards).   Progress over the last couple of days, removed the rear hubs! Next steps: - Buy bushings - Replace bushings/bearings on hub - Reinstall

      A few random issues have popped up since my last update. My WMI pressure sensor failed within about 10 minutes of it seeing liquid. It was a 20$ China special, so I'm not surprised. My name brand replacement should arrive today.  My power steering assist also decided to crap out last weekend. The usual, works for about 60 seconds after starting the car then I lose it. I dusted off my old copy of NDS and connected to the HICAS ECU. Code 4 for assist solenoid.... I tested the solenoid and it's fine.  I knew the day where my HICAS ecu would crap out would come, and I welcome it. It was the last HICAS part on the car that is now in the bin. I've ordered an SSR and I will control the power steering solenoid with my Haltech ecu. It will be nice to have proper speed referenced assist again after all these years.
