1989 f70 rocky, 2.8D
right then the fuel drain and charge warning lights have come on, and wont go off!
they came on a couple of days ago, then went off after couple of mins driving! now they come on and stay on!
I defo dont have a fuel drain, thats for certain, and the battery must be charging cos i drove the truck 20odd miles in the dark with main beam going!
i am going to make sure the alternator is doing everything is should and also test the voltage regulator!
but is there a fault or problem that anyone else has encountered that would explain this problem, or am i going to ahve to start at the igntion switch and trace the wiring problem back from there?
