SOURCE: 9v battery wires came loose. peavey 5 string bass

The negative battery terminal will go to a black wire and that will be soldered to one of the volume control cases. That makes the remaining wire easy. The negative terminal pole on the battery is the larger round one.

The preamp section has a problem. It could be anything in the preamp but is OFTEN the input jack itself. They take a lot of abuse.

Also the insert jack contacts that forward the preamp to the power amp if no external FX are used can go bad.

Additional things are circuit board cracks caused by rough handling and also controls that have had the knobs mashed in which can destroy the potentiometers they are connected to.

The amp is doing what is called "motorboating". This is usually caused when the voltages to sensitive preamp stages are inadequately filtered or regulated and the sudden load of the output stages cause a dip in the voltages sent to the preamps which in turn vary the input to the output stages starting the cycle over. This will require electronic troubleshooting and if your not skilled in that, then it is NOT a DIY fix. What you are seeing is NOT normal, there is a defect.

Try these schematics:

Please note that on the first schematic above, the power amp schematic is way down beyond the parts list and layout of the preamp section... keep scrolling. ALSO the powoer amp shows a real WIERD connection where the output transistors drive against ground and the center tap of the power supply transformer for the power amp portion then bounces around with the audio output... that is a wierd connection but it is possible.
