There appears to be an electrical problem with my fuses. Four 20A under hood fuses always fail to light the test light while the rest of the under hood fuses light the positive red light. I pulled and inspected the 4 fuses and did not see any reason why they would not work. Then, replaced all 4 fuses with new 20A fuses, they all 4 do the same thing, don't light up the test light. When I tested the interior fuses, none of them light up, including the 7.5A start signal fuse. I have been trying to diagnose a no crank start failure, including the fuses. When I test the positive starter solenoid post, it lights up the positive test light, indicating that the positive circuit from the battery to the starter solenoid is receiving current and the starter motor may be failing to receive current or the motor has failed. I will do more tests with the starter, but why do the all the interior fuses, especially the starter signal fuse and the 4 new fuses fail the light test?
