Please help me.... I have a 2008 f150 fx2. i was putting in leds in my map lights when i saw a spark. and then the lights went out. i found the short in the map light area. but now i have no power to the lights or the radio or the dash cluster or gauges or the windows. i have checked every fuse twice, pulled every high amp fuse . i cant seem to find where i blew a fuse or the circuit., i have looked up and may say it could be the 30amp circuit breaker, but i did a check with the meter and it beeps out. that is in location 401 in the panel. Am i missing a fuse link somewhere? The truck will start and run, but i have no dash, but i have power to the ac ,wipers and to the 12 volt plugs for phone chargers, but i seem to lost the power to the red wire for the radio,

 

First off I changed the 30 amp circuit breaker and that did nothing. Then I replaced the relay and all was well.
