Removing the fuse box under the hood to check for wire shortages
How can I remove the fuse box under the hood without damaging any wires? my problem is the radiator fan will not turn on after reaching the appropiate temperature. Ive checked the fuses, replaced the coolant temp sensor and ran a wire from battery straight to fan motor. so im guessing i have a short from the fuse box to the fan motor. i just dont want to cause any damage lifting up the fuse box. is there a trick or technique i could try? also is there enough wire to flip the box over?

I'm not familiar with the car or location of relays. But if all circuits are live under the hood and dead inside I would trace the main wiring harness to where it enters the firewall and disconect it and check for corrosion,broken or heat damaged wires and terminals.
50amp only clue and you dont have the book, the FSM.
nor access to alldata.com?
if you did youd, not be asking right?
my guess is that fuse is in the mains box under hood..
and is a real fuse and not a circuit breaker found elsewhere....????
old car, and can be anything this old.
sounds like fuse #33 in the main box blew. and feeds the white wire main.
USA car? ABS opted? A/C opted. sure.
top cause, shorted alternator, so take off that big wire from alternator
and see if fuse blows now. (do so with battery neg lug removed
the remove alt big wire and tape it all up, so it can touch metal.
then put back battery Neg lug, and last the fuse.
the whtte feed goes vast places and runs whole sections of
the cab fuse boxes and power windows.
if the Alt is good.
then you must start dropping all white wire loads.
if it still blows, the harness is shorted.
I personally just uses a temporary circuit breaker in place of the
50 amp to find the short and an ampclamp DC ammeter.
login to alldata.com and follow the big white wire.
Check fuse. Usually located under the Steering wheel or under the hood. You will have to use the other side of the cover to determine which fuse controls the horn and see if the metal link is broken. If both are not blown its probably a short in the wire. If it randomly just happened then its a good first guess without knowing any further details.
Usually I check all my fuses any time I am looking for a specific one. Sometimes a random fuse can be the cause, and not the actual Horn fuse that is blown.
For many years, most cars' fuse panels (orfuse boxes) were located under the driver-side dashboard. This began to changefor two reasons: Copper wire costs increased, and more wire was needed with theadvent of advanced automotive electronics. Automaker began to use two or morefuse panels as a cost-saving measure. All the fuses that corresponded tocomponents under the hood were located under the hood instead of inside thevehicle, while other fuses remained inside the cabin. Follow this steps on howto remove the fuses.
1. Raiseyour 1998 Mazda's hood. On the right side, near the battery, is a covered,black box. Unsnap the box's clips and raise the lid. The fuses are arranged inrows for easy service. Regardless of the year or model, Mazda uses thisarrangement. Replace any fuses that are defective. You might have to pull themto see whether they're blown, or you might be able to tell without pulling eachfuse. If the curved metal piece within the opaque molded plastic is broken, thefuse is bad.
2. Unsnapthe lid to the black box on the left side of the vehicle--under the hood,mid-way up the left fender well. This box is the relay panel; it may havededicated fuses inside. Check any fuses there and inspect the relays for burnspots or signs of overheating.
3. Openthe driver's door. Under the dashboard on the left kick panel is a cover.Remove the cover and, with a flashlight, inspect the fuses that are installedthere. Replace any fuses that are defective.
It entirely depends on the year and model. Most older trucks had the fuses all together under the dash near the steering column. Newer trucks seem to favor a spot under the hood. Some seem to have some under the dash near the feet and another under the hood. Without knowing the year and model though it is impossible to tell you for sure. check those spots out real quick and if you still cant find it post back with the year and model
