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

      And if you want more power, more reliably, and cheaper, go get the Aussie RB... The 4L Barra and put that in instead.

      No cats will keep discolouring the rear bar. Sends white paint a weird yellow stain. Cut and polish normally gets it out, but you'll be doing that every fortnight I found.

      Both heads will be equally reliable or unreliable depending on what you do to them.  Stock the RB26 head will flow more. You have access to the stock intake ITB manifold on the RB26 cheaply which flows really well(1000hp+).   Arguably more aftermarket support for RB26, though in Aus we love our RB30 SOHC heads too.    The only downsides to the RB26 head is if you have a VL commodore and want to keep the SOHC look.  Where you may have an issue is drilling out the rb30 block for the bigger head studs but if you are building a big power motor you'd probably put bigger studs on the SOHC head too.  This is just about finding a good machine shop, sometimes easier said than done.  RB30 head worked can make big power just like a Rb26 head, so really it actually more comes down to what your preference is for your car.  People now even making billet versions of both.

      2630s work perfectly well. There is something to be said for just using the 30 head, as it saves all the pain of the conversion, still makes tons of power, still sounds cool, etc etc. 2630 will obviously make more power again, but the differences are not stupidly big. It really depends on whether you're racing for sheep stations or not. If it's dead serious, then it's a 26 head. If it's just for fun, it could go either way. But the 26 head and the effort to get it set up, etc etc, is part of the fun.

      I've been building a 26/30 for a few years now. I've had the head built with all the good stuff. I had a 32 gtr but blew it up and yes its all going into a vl but im looking for some advice from some RB nuts on pros and cons on putting a 26 head on a 30 bottom end is it worth it Works are as follows Head -Extensive porting 1mm oversized supertech valves Supertech double springs Supertech valve guides Supertech titanium retainers Tomei solid lifters Tomei 270 x 10.25 cams Head drain Bottom end series 2 rb30 block Cp ceramic coated pistons Eagle rods Romac balancer Oil restrictions  O ringed blah blah spent a fortune And will get a girdle because the 30s arent used to handling that much rpm Nitto billet oil pump Hypertune plenum 6boost mani Refurbed astra pump thats the cover for it in the boot I did have a precision 6262 but sold it because drag car life. Currently building the ass end full 4 link floater rear end with a 2 speed  But the dilemma i have is my mate rekens I should just stick with the 30 head for reliability. Has any one had any issues with mounting the 26 head ie compression blowing gaskets etc. Just looking for some advice from people who have gone down this route. Here's some photos. Blew the oil pump in the gtr and decided to rip the motor out at the time and do a full build only to find it had been a repairable write off so went down this path.
