Well, my car was running great after changed de coil and spark plugs, then after a week it seems that the fuel pump has no enough presure, at wot my rpm go down, also you can se on the gauges that the volts always drop when i left the gas, also i have no power on the door locks, horn, dom lamp, so i clean the terminals on the battery, clean and reatached the ground points on the engine bay, then checked under my dash and this is what i found







i think this is a mess, if u look all the fuses are wrong amp, also the last two pics show wires atached to the fuses, tomorrow am planning change all fuses but i dont know if there is something that could go wrong changing them, what do u guys think? also, do you guys think the voltage drop and the loss of power/fuel presure is related to this mess?

another suggestion would be apreciated, thanks!

 

Nobody?

 

just make sure that the p.o. didn't wire something in line further down and put a bigger fuse to cover it. check voltage at the alt. to make sure it's around 14 volts when it's running. wrong fuse won't cause voltage drop, it'd just pop if the load pulls too much current.

 

Well i replaced the fuses and now i have all lights, horn and locks working, i checked the battery 12.4 engine off, 14.2 on alternator output and battery with engine on, also the wires red and brown of input on the alt has 12.2, everithing seems fine but the output of the alt is conected to a ground where another things like the headlighs and turn sinals connected to ground, the output supossed to go at the + battery, at tjis point i cant understand how its posible that the battery hasnt drained, how is charging if the alt is not wired properly???? I was gonna to connecter the alt oitput to a fuse and then to the + terminal on the battery, but i want to be sure that im not gonna hurt anything, what do u guy think?

 

you sure it's not the distribution stud? if it's filthy it might look like a grounding point. by all rights, you'd have sparks flying if it were hooked directly to ground. the main charge output on the alternator should have fusible links in line between the battery and alt. You would need a 150 amp slow blow fuse if you were to go that route. double check voltage off the battery studs to see if you get 14 volts while the car is on.
