Does anyone have a picture layout of the fuse box on a beretta z26 and which components they power. I got the repair manual and it doesn't have it in there. The fuse box cover is gone so its not there. I look on the internet and still find nothing about what fuses go to what components. I believe a have a short in something that is causing charging problems. But i can not find any where the fuse layout or diagram for this f****** car anywhere! I had a problem with this a few months ago and tested the alternator and it's good. It was a fuse problem then. This time ive tested the alternator by the manual instructions and it tested good. Everything points to a short somewhere. But still no charging and no clue what to try next.
Go to a wrecking yard and get a fuse box cover. You can also test your system yourself for a short or parasitic draw. First, shut off all the car's lights and accessories then close all the doors. With the battery in the car, first remove the negative battery terminal. Now, using a multimeter set to the DC volts scale put one probe on the negative terminal of the battery and the other probe to ground. Read the meter. If you read more than about a quarter of a volt, you have a draw somewhere. Troubleshoot the draw by having someone remove fuses one at a time until you see the meter voltage drop. When you see the voltage drop, you’ve found the circuit in which you have a power drain. Thoroughly examine that circuit, area by area, until you locate the reason for the voltage drop. Isolate and repair the problem. If this doesn't fix the problem, take extra care for a few days and see that all the lights are off before you walk away from the car for the evening. It could be something so simple as a door that hasn't closed fully, causing an interior light to remain on overnight or maybe a bad switch on an under hood or trunk light. Any of those are more than enough to do the job. I've done it myself, more than once. Usually, a full battery charge will take care of it. Even a jump start and running the car for an hour or so should build your battery up enough to get you going again as long as your alternator is doing its job.
