Dodgey bighorn electrics, fuel light

[mortar]

So iv just brought a bighorn and have noticed my fuel light flickers on and off at about the same rate as you would expect from indicators. Its intermittent and has no reference to the amount of gas in the tank it started doing it from about 3/4 full and is still doing it on and off down to just under 1/4 of a tank.

If anyones had this happen let me no how you fixed it

Also while were on dodgey electrics my intermittent wipers only work sumtimes and when the do they have a mind of there own as to how fast they come on and off
