Changing the output Jack on 1985 Peavey Dyna Bass

To wire a Dean Edge bass guitar with four pots (potentiometers) and a battery, you will need to follow the wiring diagram for the specific model of your bass guitar. Here is a general overview of the wiring process:

1. Start by connecting the ground wires to the pots and the battery. The ground wires should be connected to the ground terminal on each pot and the negative terminal on the battery.
2. Next, connect the power wires to the pots and the battery. The power wires should be connected to the positive terminal on the battery and to the power terminal on each pot.
3. Connect the pickup wires to the pots and the output jack. The pickup wires should be connected to the pickup terminals on the pots and to the input terminals on the output jack.
4. Connect the control wires to the pots and the output jack. The control wires should be connected to the control terminals on the pots and to the output terminals on the output jack.
5. Test the wiring to make sure everything is working properly. If there are any issues with the wiring, you may need to double-check your connections or consult the wiring diagram for your specific bass guitar model.

It is recommended that you follow the wiring diagram provided by Dean or consult a qualified technician if you are not comfortable wiring the bass guitar yourself. Improper wiring can damage the guitar and potentially pose a safety hazard.

Broken cable inside, possibly at the output jack?
Or a failed potentiometer (volume or tone)
Pull the back plate off, and have a look at the wiring, Trace it with an ohmmeter to check for continuity at each step.

First - Check the connections on the speaker itself - when speakers don't work. it's usually the wires from the power amp section to the speaker. If those are OK, try replacing or bypassing the headphone jack - you may have a short in the output jack. Good Luck

there is a switch in the jack socket that lets it know jack is in use. when the stop working it usually means you need to change the jack, you cannot bend the part back with out breaking it so just best to change it. you can get a replacement jack from ebay, or any electrical supply shop that does small components.

You'll need needle nose pliers, small phillips head screwdriver, soldering iron, electronics-grade solder, socket screwdriver or 1/4" wrench, black electrical tape. Purchase necessary replacement jack. Remove plastic electronics cover plate, located on the back of the body, behind control knobs. This will expose the electronics cavity. Locate existing jack and its wire connections inside the exposed cavity. Remove any electrical tape covering the jack connections. Using a hot soldering iron, touch each of the two soldered input jack connections, one at a time, just until the soldered connection melts. Then, disconnect the associated wires (taking note of which wire connects where!). Once disconnected, loosen and remove the nut on the outer part of the jack that holds it onto the guitar body. Remove the old jack. Insert the new jack (with the nut removed) into the existing hole, from inside the electronics cavity and tighten it in place, on the outside of the guitar body, with the nut. Re-attach the wires to the new jack, by using needle nose pliers to wrap them tightly around the correct posts. Touch the hot soldering iron to each post and apply a small amount of solder to the post as it's being heated. Once the molten solder runs over the connection and looks shiny, remove the tip of the soldering gun. This process takes only 2 to 3 seconds. Let the connections cool for a few seconds. To insulate, wrap connections with black electrical tape. Replace cover plate.

If it is the socket on the bass, it should only be 2 wires, on the 2 ears of the socket. He must have soldered it to the wrong place. The wire from the pickup switch(if more than 1) or the volume(if only 1) should go to the part of the socket that touches the tip on the guitar cord when plugged in. The other is ground and connects to the backs of controls and switches throughout the instrument, even to the bridge and tailpiece.

Make sure you have two wires soldered to the output jack on the bass. having a wire lose is not purposely put like that, for no sound from the bass then that wire is either from the pickups and connects to the pots on the bass or on the output jack. I would suggest taking it to an authorized dean dealer to inspect the wiring.

Pretty straightforward and cheap to do. You will need a replacement jack to fit the bass and some shieled audio cable and a soldering iron and some tools. Remove the rear cover plate screws and then the plate to expose the controls and wiring. If you can take a photo and email it to me I can show you what needs doing to get you up and running. email Karl ay [email protected]

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.

VIsit Peavey's website at http://www.peavey.com contact their customer support and you can order a wiring diagram on how these pickups should be wired. I've always been able to get any diagram I've needed for any of their products, some times you have to pay for them but sometimes they can be downloaded for free.
