    No speedo, no fuel gauge, no temp gauge, no side lights

    After they failed, I changed the screw and nut for both ground points in the right side of the chassis. I also cleaned thoroughly the ground in the firewall and the one attached to the gearbox. I have checked out all the gauges connections behind the dashboard, everything looks ok. Last time it happens, I tried moving the nut of the starter and everything worked again, but it's not happenning now. Please somebody help me, I'm going for a 1.000 km dessert travel and I can't go without temp gauge (my Nanocom was stolen yesterday, I recovered it, but the thief take the cable, and I can't find it here in Colombia, so I don't have this option).

    I almost forgot. Additional to gauges and lights failure, engine feels kind of "rough", like potentiometer in bad shape, but as soon as everything works fine engine works just fine again. I also clean and move black and red ECU connectors with no results.

    I took every fuse out (both the ones in the firewall and the ones under passenger seat), and verified fuse and plug for corrosion. No damage in any of them...... also took out every relay with no result. How can I know if a relay is OK?

    Did you test the fuse's with a multimeter? I have visually looked at a fuse that I thought was good but in fact was blown.

    You should really only need to check the fuses that relate to powering the gauges.

    Checking the relay can be accomplished by supplying 12v to the relay (with an earth connected as well) there should be and audible click. You can also use the multimeter to check that the relay is actually switching the input to the output terminals.
