Hey all, Well I've been having fun putting on white face gauges, gauge rings and led's into the cluster. Well I'm pretty sure my tacho, water temp (which I don't care about anyway as it didn't read properly in the 1st place and I have an aftermarket one), speedo, boost and oil gauge are working fine. But my fuel gauge needle has gone past the full mark by a fair bit and the low fuel light is on. I tried to set the needle before I put it in back to 1/4 tank as that's how much I have in there. Does a fuel gauge that goes off the chart full and has a low fuel light on have a problem with the gauge? Oh and I dropped my clear gauge cover, broke it! And my air con pod isn't working now...ahh the fun of working with electronics. Thanks, Marc.
possible you damaged the flex circuit board on the back of the cluster?? Sounds like both are getting earth when they shouldn't or similar.
Hmm hopefully I haven't shorted something. How does the Low Fuel Light work? Is it read off the needle shaft position? I'm wondering if I've managed to spin the shaft to the wrong location. Also, with the speedo, I've put the 300kph face in with the supplied resistor but my speedo is constantly out by 10kph (checked it against my gps). Is there a pot or something I can adjust? Or will I have to just move the needle?
Mine goes up to about 85% when the tank is full, and drops to about -15% when it's empty and the light comes on.. First time it dropped below the empty line, I just kept driving and driving to see if the light worked. Luckily it did =)
I've calibrated all my gauges including the speedo using my GPS. I filled my fuel tank to full, removed the fuel needle then put it back on after a few minutes to reset it to full. So I'll run it for a few days and see if it is still reading right.
The low fuel light has it's own sensor in the tank. I used a trimpot on mine (a 10-turn version) of the next available higher resistance. It gives a cool range of adjustment. Like yourself, I calibrate to GPS and datascan, and it's (Mine's) accurate at 40, 60, 80, 100 and 120KMPH. above that I guess it doesn't really matter anyway (and can't legally test )
