Fuel gauge
Posted: Sun Nov 19, 2006 5:18 pm
When connecting my fuel gauge it always goes "bang" to full.
(tank is only 1/4 full) Green plus to B double terminal, green black to T single. ground to fixing bolt. Plus delivers 12.6 v from batterie. Green black resistance test against ground shows infinite resitance. Black ground works fine with instrument bulbs etc. B and T terminals changed over make the finger go "bang" to empty. Shouldn't be digital, should it?
My car has negative ground and worked this way before I took it apart...
How to bench test the instrument? Is the tank resistance device at high resistance on empty? Could a split green black line to the tank be the cause?
