you need to inspect all AC WIRING, to find the SHORT, thats causing the fuse to blow ! donot put another fuse in until you locate the shorted condition, ( bad connection, frayed wire, bare wire touching metal along this circuit, you might have a bad switch, your ac has two switches under hood, one @ high pressure side and one @ low pressure side. and your main control switch, check all wires & connections
check the mains chord, also check the power in the wall socket to which the projector is connected. if all these ok then,may be its power supply side have some problem. its an smps power supply. just check its input fuse on the smps. if it fond faulty the do not replace it suddenly. check is there is any thing faulty on the smps board. because the fuse will blow off only if there is any problem in smps. check it first before inserting fuse.
check the wire because if the fuse keep blowing there's a wire somewhere on the car that has contact with the frame so everytime you put your car on reverse the 12V wire shortcut on the frame so the fuse blow check all your positive wire and your bulb as well
The reason your blowing fuses is the amp needs at the least a 150 amp fuse on the wire that runs to your bat. There are fuse blocks that you can put 4 40amp fuse and theres the high dollor ones that you can put all the way to 200amp. When you trun up your amp its drawing to much current for the little 40 amp fuse that you have and will blow it everytime. I recomend Running a 4 gage wire to bat and ground with same. Get you a 150 or above amp fuse from a car audio shop somewhere. anyway sounds like from what you decribed, theres nothing wrong with your amp just the wires and fuse are not big enouf to handle the current that your amp pulls.
HI Check that you use another power outlet,see that the power cord pins are clean,and not burnt or use a new cord,the connection at the projector makes a GOOD connection with the new cord. You will need a multimeter to check if there is voltage at the inside of the projector cord connection.You will have to remove the internal fuse before you check the the voltage inside.If all looks good then you will have a fault on the circuit board-shorted component on power supply side or further in on the circuit(need an electronic tech for this).Hope this helps--Jay SAFTEY FIRST ALL TIMES--NOT SURE DO NOT DO IT
