97 crown vic air bag code 12,fuse 10 was blown replacd and it blows right away, 6 ohms to ground on non power side of fuse, where do i go from here?

In involved fuses #5 & #10 15 amp in main fuse panel

from Ford Service cd
Fault Code 12

Air Bag Deployment Circuit Drop in Battery Voltage

Circuit Description

Normal Operation

The diagnostic monitor measures the voltage at pin 13 of the diagnostic monitor connector. Voltage at pin 13 should be equal to battery voltage. If the voltage measured at pin 13 drops to less than 9 volts, the diagnostic monitor will flash out code 12.

Possible Causes

A drop in battery voltage at diagnostic monitor pin 13 can be caused by:

1.An open circuit that would prevent battery voltage from reaching diagnostic monitor pin 13.

If the instrument panel fuse and/or the power distribution fuse are blown, be sure to diagnose the system for possible causes 2 and 3 below.

2.A short to ground in Circuit 611 (W/O) or 612 (P/O) may result in a blown instrument panel fuse and/or power distribution fuse.

3.An internal short to ground within the safing sensor may result in a blown instrument panel fuse and/or power distribution fuse.

4.A problem in the charging system causing battery voltage to drop below 9 volts.

Its an ic within the power section of the player initially fuse kept blowing up shorted fuse and that part blew,it got 8 pin 4 on one side 4 on other. The player is philips DVP3026/94 Type.what is the ic...

If you wish to get more details, check this link. It has schematic diagrams of power section circuits, to some popular model audio/video devices. Hopes it might help you. Surf the site with patience.
Pull up previous posts by its left sidebar, or type in the brand name and model number to of your set, to its search box, and press 'Enter' or view it in Mosaic / Timeslide option.

Crest audio ca4 blowing fuse

There is two possibillities to fuse blown off due to hi current flowing through fuse more than 3amp.because power supply componant like rectifying diode, filter capacitor or regulator ic ,regulator transistor shall be short circuited.
if you are tech......just remove amp. supply.from main power supply...try with another fuse........if fuse ok, fault is amp side, or if fuse blow off ...power side problem just....maximum fault comming on varistor ,diode, filter capacitor, .........
if you are not tech......... give to local authorised tech.......

This is an indication that you have a short on the power supply section.

It can't be fixed by replacing the fuse alone. I've suspected that you have a short on the following parts :

1.Power Cord - even very low of chances but still to be check.This is due to frequent bending and pulling.

2.Rectifier diode

3.Main filter electrolytic capacitor

4.Voltage regulator I.C.

This is the common parts that might be shorted and made the fuse blew. #2-4 is quite technical and need an expert to do the job so I

It was 110v and plug in 220v -no power

There are several parts that are going to be check like the ff:
1. Glass fuse - Some unit replacing the fuse alone fix the problem.
2. Stepdown transformer - if it has then check for open/shorted winding.
3. Regulator I.C.
4. Fusible resistor.

All parts are on the power supply section.

1 & 2 can be DIY but 3 & 4 are needed to do by the techinician.
If you replaced the fuse and blew again then you have a shorted parts. However if it has no reaction then you might have an open parts.

Pls rate my help..

Every time I plug it up the fuse blows

This is a clear indication that you have a shorts on the low voltage power supply section.
Replacing the fuse alone can't fix the problem unless the shorted part(s) is isolated.
I've suspect that you have a shorted on the ff part(s):
1. Power cord.
2. Posistor
3. Rectifier diode
4. Capacitor
5. Voltage Regulator I.C.

All said parts are located on the power supply section.
It is quite technical if you are not an expert but quite fixable.
I've advice you to lood for a qualified technician to locate the shorted parts.

Pls rate my help...

Blowing fuses

Maybe the audio amplifiers IC are in short circuit or the alimentation board are damaged

System won't power up


Based on your description, we can limit the fault to the power supply board and in particular to possibly 3~4 components:
  • bridge diode;
  • filter capacitor (mains);
  • regulator;
  • filter capacitor (secondary).
blown fuse indicate a short in any of these.

As Jaime867 has suggested, in the absence of a readily available replacement board, component level might be the best alternative at the moment. Having posted the most likely culprits further narrows down your troubleshooting. Could you pls post back the part number of the smaller IC either 4 or 8 pins?

Alternately, pls check for the presence of a VDR, it would look like a coin (often green in color or something else) with 2 pins. They have been known to short out also and cause fuse to blow. One possible indicator is chipped or flaked of one side or a hairline crack on top. If it is chip, there would be a silvery color on the inside.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Hok up amp and all fuses blow on distribution block

somehow, DC car voltage has gotten to the speaker outputs of your amp! your fuses are saving your speakers from meltdown. your amp has melted down. toss it after checking with ohmeter as follows: disconnect amp completely. red wire from ohmmeter to +12Vin. black wire to SPK+. if ohms are anything below 1000 ohms, then toss it. An electrical short is equivalent to flooding your entire house with a leaky faucet. No telling what that rapid current will encounter along the amplifier section. you could get lucky and find all power MOSFETS have shorted and replace them. good luck.
