This sounds like the main rectifier diode/bridge is shorted. If you can rpovide the make and model, I may be able to give you more details.

Thanks,

On the small Fender 15G/15R amps, if the power amplifier IC is bad it will immediately blow the fuse when powered. To check the the IC you have to remove it from the chassis and measure the resistance between two of its three legs. You need to find a schematic for your amp online and measure at the test points with a meter as a starting point.

Blowing 50 amp fuse under hood in 2002 crown vic


To blow a fifty amp fuse would take a major short circuit, referred to as a 'dead short' this means that a wire with 12 volts positive (+) is in direct contact with an Earth (-). If you follow the path of the power you will find where this is happening. sometimes you may need to temporarily disconnect some contacts

No sound


You would NOT use a stereo cable to plug in your guitar.

The stereo cable would carry the battery voltage back to the amp and MAYBE cause the fuse to blow.

You use a MONO instrument cable for your guitar.

The ring connection is use to complete the circuit to turn on the battery in most guitars.

Replace the fuse ONCE and get the proper instrument cable (NOT consumer audio cable) for your guitar.

If fuse blows again, take amp to shop for service.

Blowing of fuses


The reason your blowing fuses is the amp needs at the least a 150 amp fuse on the wire that runs to your bat. There are fuse blocks that you can put 4 40amp fuse and theres the high dollor ones that you can put all the way to 200amp. When you trun up your amp its drawing to much current for the little 40 amp fuse that you have and will blow it everytime. I recomend Running a 4 gage wire to bat and ground with same. Get you a 150 or above amp fuse from a car audio shop somewhere. anyway sounds like from what you decribed, theres nothing wrong with your amp just the wires and fuse are not big enouf to handle the current that your amp pulls.

There could be a short in the rectifier diodes or in the transformer itself. Can you take some measurements inside the unit?

Let me know.

Does it blow the fuse if you disconnect the RCA cables and disconnect the speaker wires from the speaker terminals of the amp?

Does it only blow the fuse after the head unit is switched on (only after remote voltage is applied to the amp)?

Ashdown Perfect 10 Bass Combo keep blowng 2 man fuses


What main fuses? Fuses in the car electrical system? If so, your amp is too powerful to run through the cars electrical system, you should get a heavy guage wore ran straight from the battery, with its own dedicated fuse placed in-line, ad close to the battery as possible. Wait, is this a bass guitar combo??? Open it up, if there's wax coming from the power supply, thats prolly the culprit. Check for any obviously blown resistors or any short circuits. But most likely, its not gonna be user-servicable.
