It's normal. I have the dealer service manual on CDROM and have read about the funky little systems our GTR's.

The relay(S) you are talking about switch the HICAS 4WD pressure pump on and off. It usually switches in for 1/4 sec every 30 sec or so. Think it tests the pump and solenoid valve and primes itself. (hicas pump is located on top of rear diff).

If you disconnect the relay the pump will not operate and the 4WD light will stay on in the dash until you reconnect it and start engine again.

Hope that helps.

Sean,

Can you post up the relevant section from the service manual?  

The relay in my boot is making an very loud clicking noise and causes the voltage meter to bump and lights to dim momentarily every five or so seconds.

I'll see what I can do. Does your 4wd light come on the dash. If it does theres a fault. My lights used to dim when it went of too but changing the batter fixed it cos it was stuffed on mine.

No, the 4WD warning light stays off unless I pull the wires out of the relay :rofl:

Cheers,

My lights and instruments didn"t dim once I changed the battery as well. So it could be that your bat could be on the way out or it doesn't have enough capacity?

Hi Sean,

The battery is only a couple of months old, so its doubtful. Its possible that a higher capacity battery wouldn't experience a dip in voltage, but its not really a major issue and only really noticeable at idle.

I have done some more research and it seems that this is not an uncommon "problem". Its just a noisy (but working) relay. If I have time, I might play around with better earthing the relay.

Lucien.

      I just got to work and skimmed through 61508 and 61511. I was surprised the CSA adopted both, but neither are enforced. To recap what I read, it states that in a perfect world, they should be segregated but they acknowledge that this is not industry standard and clearly mention that they allow mixing of safety and non-safety. 61511 also mentions software segregation like AB does in their safety PLC's.   Now if only I could go back to control, let alone safety over comms. In my current line of work, we're only allowed monitoring and basic control over comms. Everything critical must still be hard wired as much as possible.

      I've unfortunately never been as they're on the complete other side of the continent and another country that isn't currently letting us in as easily as they use to. I even heard their stop signs over there actually say "Stop" instead of "Arret". If I decided to trek the 48h drive, I wouldn't know when or where to stop haha. Whenever I order parts from UP Garage, I order from Japan as it's cheaper. Same with GKTech... oddly enough, it's cheaper shipped from Australia then it is the US.  UP Garage Japan operates their US leg though, unlike Tomei. If Tomei JPN had the power to close down Tomei USA, I'm sure it would be done in a day. They're two completely separate entities. Tomei JPN messed up somewhere originally agreeing to its creation and got sacked big time.

      I asked someone about this and he told me about the Audi 1.8T engine. But I think it would be difficult to swap

      I don't know that machine specifically, but I'd personally go for something with a little more kick than 130amp. Around up to 180 would be good. At the 6mm range, you're really pushing the machine hard and don't have a long period you can run for with out needing to give it a rest. Lots of MIG machines come with a regulator and hose. A lot will come with a starter roll of wire too, but it isn't too expensive to buy. I'd recommend NOT buying a massive roll too, as you don't want it sitting around FOREVER in the machine between uses and potentially going to shit. For thin sheet metal, get a roll of 0.6mm if you're doing over 3mm and above, switch over to 0.8mm wire. Even by 2mm you'd probably really want to switch. As for gas battle, it's all swap and go style now. You'll pay a bottle deposit, and then X amount to swap for a full one. I think it's like $200 or $300 for a D Size bottle upfront as "deposit", and like $110 to $150 per swap. My D size CO2/argon bottle lasts a fair bit of welding on the MIG. And I run an E size bottle on the TIG. For DIY MIG, stick with a D size bottle. If you really start to get into a LOT of welding and doing it really regularly, then upgrade. If you're like most DIY car guys, one D bottle will last you 2 or 3 years easily. I think I've been on my current bottle about 5 years. It is starting to get low, but I've been smashing it a lot more the last 6 months.

      SR20s came with cars like the Bluebird and Primera, but the RB20 never came. The ones in Turkey were either brought in specially or from abroad. That's why RBs aren't as common as SRs. And if a part breaks or I need to replace it when doing maintenance, it's harder to find parts for RBs.
