How can I tell if my Fuse Box is running?
Check for constant ground to the relay. Identify the slot in the fuse box that terminal 85 plugs into. Set your multimeter to read voltage on the 20-volt scale. Plug the negative lead of your multimeter into the slot for terminal No. 85. Touch the positive lead to the positive battery terminal. You should see constant battery voltage.
