Beutler zte2s my a/c fuse blows several times throughout the summer. I use a 15amp TL fuse. What is causing the problem.

USA spec. car?
2007 Nissan Altima 2.5 answering only for 15amp fuses !!!!!
fuse blows. fuse name not told nor its location told at all
sad face sigh.
2.5L calif car or fed car not told and are DIFFERENT as is Export.
i will answer now (tossing dice) land on FED car schematics.
service manual answered
22 pages on PCM. schematics. ouch
fuse f42 and F43 is 15amp, and runs cpu in IPDM
fuse f32 is fuel pump see how tell fuse ID tells what is shorted?
all above are IPDM fuse box fuses, under hood
f43 is throttle control valve too. twb motor drive.
f42 runs ECM/PCM and lots of things.



F53 is fog lamps.
my wild guess F42 blows. and runs ecm relay to here.

to find the short one must disconnect all loads to fuse the blows

to find which device is shorted.
use only 15amp fuses, not larger ever. here.

blown fuses are an indication of an overload of the circuit ( failing electrical device --relay or module ) or a dead short in the wiring after the fuse. The problem may be in the ECM area. Run the fault codes to determine if electronic problem

What does the fuse power?

Make sure you have 24 volts @ the transformer inside the furnace....If you are reading 18V across the Red & Common, try reading across R & anything else ie G, Y, W. If you have 24 volts there, then trace your common wire & make sure it is not splice somewhere in between the tstat & the furnace. If you have any unused wires, hook up the different color wire & make sure you use the same wire for common @ the furnace.

look aver the harness sounds like there is a spot that rubbed away the coating and shorted out against metal

DOES YOUR BIKE HAVE CORRECT IGNITION COIL IF IT TOO HIGHLY RATED I.E A SPORTS COIL YOU WILL PUT EXCESSIVE CURRENT THROUGH FUSE CAUSING IT TO BLOW. IS THE FUSE HOLDER SECURED DOWN VIBRATION CAN MAKE FUSES BLOW LIKE BULB FILAMENTS {TRY A 15AMP FUSE] IF THAT BLOWS DEFINATE OVER RATED COIL

When a fuse blows you have 2 choices

Replace it once or just go to the wiring
diagrams & start diagnosing & testing,
until you find the cause of the electrical
system problem causing the high current

You need to know what is on that fused circuit

Unplug the overhead console. If the problem
goes away, you know the console needs to
be checked out. Or you work on the signal
problem WITH WIRING DIAGRAMS

You wouldn't go on a road trip without
a map,if you never been there before !!

hi
I think the problem is on when the key is turn to rotate and to engage the starter motor and it at this point that the cable curring the current on to the starter motor it then the fuse gets blown , in my opinion this cable is shortening across the chassis causing the fuse to blow, or when it get to the starter solenoid a faulty solenoid absorbs accessed electric current causing the fuse to blow

Your charging regulator has failed. The reverse voltage caused one or more diodes to fail shorted, and this short is blowing the fuse.

Thats the fuse for the ECU, engine control module, and is a 15amp for gas 2.0. i would locate the ECU which is under the center of the plenum in the engine compartment and disconnect the long plug. Check for green discoloration on the multipin connector. Sometimes moisture will get in there and short some of the pins together. Leave ECU unplugged and replace the fuse. If it still blows cause is between the fuse and the ECU.
