Fuel gauge sender - bad earth, corrosion of screws
Posted: Mon Aug 16, 2010 9:27 pm
Hi,
I've been checking out my non-working fuel gauge and am pretty sure it is down to a bad earth (thanks to the fact sheet).
I get a full tank displayed when I short the two wires, and I've done around 150 miles on a full tank and get a resistance of 27 ohms between a cleaned up screw head and the green wire connector.
I therefore want to put in a new earth but have been unable to remove any of the 8 screws holding the sender unit to the fuel tank as they are all corroded. I've tried WD40 to free them, but with no joy.
What is the best way to try to remove these? Is it safe to drill off the heads and take the threads out with pliers ( if necessary lifting the sender unit out)? I assume no other part of the surface is connected to the fuel gauge sender earth.
Thanks,
Dave.
