Hello all,

Just recently got my R33 back after a serious short circuit fried my PowerFC and CAS, caused assumedly by an earth from the motor being improperly placed on the alternator. So now I'm paranoid and want to go around and check all my earths but days of googling still has me stumped as to locations, so if any whizz out there could let me know where any/all earths are or should be on a series 2 R33 you will get the love and gratitude of a hairy dude on the internet

Thanks in advance!

The diagrams are good but visual pictures would help best. Can anybody please show pictures of where exactly the engine body earth cable is bolted to? Also it appears the alternator has one earth connected to it also, but where does the other end go to?

Sure. I'm an anybody. 

I've included some handy colour coded arrows to assist with your enquiry. 

Red = engine body earth cable 

Yellow = alternator ground wire. 

In the pictures you can see that the engine body earth cable and alternator ground wire both connect at the same point, they are stacked. The same way the wiring diagram shows that they are stacked. 

Now when looking at the pictures, don't be distracted by the fuel filter. It is fkn sexy, but focus on the arrows and the ground wire. Also the Kryptalon fuel lines are pretty sexy too, don't be distracted by that either. 

If you need any more pictures of my engine by, you can hit up my onlyfans account.

Buddy you're just the best!!! It took me awhile to see the arrows because I was focusing on those sexy fuel lines and filter setup 🤭
 

Also @GTSBoy I realize you're making a snide joke but in my case I am missing the ENTIRE section of that loom, so I don't have the alternator-starter-transmission harness to even trace wires. That's why I needed to see a visual indication of the OEM locations since I will be building that part of the loom from scratch and last thing I want is to start a fire.

So just to recap, it seems the grounds on a stock 25DET 33 are as follows:

1. Engine block (near dipstick) to chassis rail.
2. Alternator to chassis rail (same point as above)

3. 2x next to the coolant temp sensors at water outlet.

4. Passenger side strut tower to exhaust manifold
5. One earth cable at the back of the motor

6. One earth cable near left headlight

7. One earth cable near right headlight

 

It's much clearer now. Thanks guys!

      After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive

      R34 25GT Engine Light 21

      Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.

      I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.

      No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.

      Can you mount the ATTESA pump in other locations?

      Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
