my mate just got his S6 rx7 in the country... he had to jump start it as the battery was crap..

now there are 2 Greddy electrical (water and oil pressure) guages that dont work anymore..

also a pivot temperature controler (for fans) not working either.

anyone know if they have an internal fuse or are they usually fused somehwere else?

sooo many wires running all through the car (dunno why they alwasy do it that way) but just checking for any hints on it.

mainly the pivot unit as it cotrols the thermo fan so it cant be driven until thats fixed

i think the only way to get to the bottom of it is to go through tracing the wires back to where they are getting their power from. as far as i know none of those modules have any internal replaceable fuse. Whoever connected them should have used a fuseable power supply. In fact probably the quickest way to figure it out is to just check all the fuses out on the fuse panel. the fact that something blows does suggest some other problem though, possibly too many things drawing current fron the one source. man i hate electrical problems! good luck :)

Is that the black series 6 rx7, f*kn nice machine he has ... take it to an auto elec. Dont even risk backyard electrics if you dont know exactly what your doing. Not safe to you or the car.

All the best

As long as you dont open the bonnet, all the electric system is only 12V so dont be afraid to have a poke around.

As LO R33 said, get a multimeter and have a look. If they have power, you have probably fried them as the were hooked up to a non-fused source (like straight from the battery)

If they dont have power, the odds are a fuse has gone. I'd be checking the cigarette lighter fuse first, as most people run heaps of stuff off it as its easy to get to and has positive, earth and illumination (what most gauges need).

thanks for the hints there guys ....

but this is funny ... it was actually all drawing power from the ECU - crazy japs :)

but it was only a coincidence that when he jump started it a connector that was running the 3 units disconnected behind the head deck .. oh well its sorted now ..

hey Coupe .. the car is red. and race import only so its fine to be doing a back yard ish job as it is still to be stripped out etc.

this is it .. small pic though

wow drawing power from the ecu... i usually connect things to the cig lighter circuit as im a bit paranoid about things like that.

yeah i cant see why they would take the power from there .. but they did .. and the issue was sorted .. just a loose connection from the ign switch in the fuse box to the remotes for all three units

      Yet another RB Neo misfiring thread after reading all the others.

      Good tips, will get on those tomorrow. When doing the maintenance I did move a few of those connectors around, and things that are old tend to not like moving around. (Like me).

      Don't try it. It will be shit. Better chance of damaging the engine than gaining any knowledge about the old one. Maybe, but unlikely, especially if the O2 sensor is working. You can use NissDataScan to look at the stock ECU.   Cleaning the AFM is seldom necessary and seldom helps. The R35 coil & loom conversion should eliminate dud coils or plugs. But as you still have misses - look to the plug where the coil loom connects to the engine loom, and the CAS plug. Need quality connections there. Also look to injector plugs. And the AFM plug while you're at it. Also look to whether your injectors are clean and flowing evenly. Get them out and onto a testbench.

      Good to know, I feel like I am in for a rollercoaster ride that looks like a sine wave.

      Hey folks. I've been lurking and browsing the forum for a while, since I got into my head that I wanted a skyline. Having purchased an overpriced completely stock GTT, (only "mods" it has is HKS pod filter and catback) now that it became legal in the US, it was all glorious and sututu noises here and there. But then I wanted to do things right and went to do basic maintenance. After all the fluids, filters done, I did the spark plugs, that's when the problems started.. First the car started spluttering at around 4.5k RPM. Which I gapped down the new plugs and that solved the sputter there, but the car now always misfires at idle with pops when lifting off and shifting 2nd to 3rd. Similar to the issues in this recent thread. I've been banging my head against the wall, reading the threads here and trying suggestions for a couple months now, so decided to start this one to explain exactly what I tried and what is going on. The symptoms of the issue: Idle and low revs misfiring intermittently. You can hear the exhaust tone change and the shakes on the shifter knob. It happens frequently, but doesn't seem to have a rhythm to it. Pops when backing off throttle. It pops and or burbles almost feels like it spits fire when it pops. (Happens mostly in 3rd gear at around 2k RPM). When under load and after 6k RPM, it also pops when shifting from 2nd to 3rd. There's a ticking noise at around 2k RPM in 2nd gear going downhill, seems unrelated though but I am out of educated and downright dumb guesses. Not noticeable lack of power when putting the car into load. The attempted diagnosis and solutions: Unplugging coils when the car is running This did nothing to change the idling and tone shift for every cylinder. Checking the exhaust headers with thermometer They all are within what I'd say it is margin of error of the laser thermometer New spark plugs Tossed two new sets, copper, iridium and using the old ones, still misfiring, even re gapped to 0.8mm, still same thing. MAF cleaned with the "specific" spray cleaner No changes in the issues what so ever. Brand new loom and r35 coil conversion (was going to add the r35 coils anyway) car runs arguably better, still misfires, but seems like does less frequently. Placebo? Code 21 now being thrown, thanks nissan gods. Removed the CAS to check the shaft for play or anything. CAS seems all fine, nothing that indicates any issue, visually speaking. Things to attempted next: Ordered a new MAF (chinesium from Amazon, to be able to return regardless of result). Fuel with proper gas, maybe it is this California water that they sell as gas that is to blame? Plugin the link ECU and check the info using the built in base map. Go back to BMW and eat my rob bearing breakfast without milky oil mixture.   Do any of you have experienced anything like this or have any suggestion?
