OK wire off!

Ok drained all the horible stuff up from the bottom of the tank.

Carbs have said horible stuff in them and need a clean.

Horible stuff dislodged

Opperators needs to invest in a buzzer from the light supply wire to the
opperators side door switch.

If battery is drained to under 30% of it's capacity it never recovers
supprisingly littel of it's capacity, %70 at best. Ok I can't remember the
exact figures but.... If added to bad battery in the first place you will
have no power. Opperator did try to recharge battery?

In short ;-) no! The power to the fule gadge comes from the regulator then
from the ignition.
If the temp is working then it's a problem with the gadge it's self(having
stripped one I doubt it) the sender, or most likely the wiring!
Look to see if there is voltage from the coloured wire of the sender to body
earth. If so it's the sender or the wireing to the earth, check resistance
of black wire of sender to body earth, 0 ohm good for wire, infinity ohm bad
for wire! If it's the sender your on your own I don't know about doing them
althouh there thoes that do! If there is no voltage at the sender coloured
wire then you need to investigate the wireing loom(eek) pull the center dash
pannel to expose the back of the fule gadge. With power on short the non
supply wire (look in wiring diagram) to earth, the gadge should go full
scail. If not and swapping the common coloured connections of fule and temp
dosent work suspect gadge else wireing!

Yes more than likely the float stuck open flooding the car. I am afraid to
say you may need to strip your carb for a good clean!
>Other causes?
Some one is out to get you!
