No sound from Bass

Hello everyone

Yesterday my Schecter stiletto stealth 5 bass just stopped and i mean no sound coming . i did troubleshooting from changing battery to looking at wires to make sure nothing loose . which left me with only 2 things to suspect . either preamp died or the pickups .
when i hook up the bass to my audio interface and move the volume knob on and off i see the green signal in my audio interface but no sound coming . what you guys think the issue could be ? if its preamp , what should i replace it with ? its Master Volume/Blend/Active 2-Band

thanks

 

I tried my 4 string on the same audio interface and wire , no problem from audio interface or external wire

 

Yes i tried it on my blackstar amp no sound

 

technically its telling me there a signal from the guitar to the interface , however when i play the bass the green light does not come on which telling me the signal from the bass get cut or somehow off . that green light briefly comes on when i move the knob . either the preamp is dead or the pickups . wish i can troubleshoot this more . the only way for me to know is if i tried the preamp from my 4 strings and see if that makes a difference . the thing is i don't want to cust wires up in my 4 and end up with 2 basses down . unless somehow i can disconnect the wires from the preamp without cutting it

 

you mean connect the preamp from my 4 to my 5 ?

 

ok , connected to my interface . no battery

 

i noticed the battery is hot when i took out . should not be that hot .

 

i will try different battery , will leave it there for few minutes and see how hot it gets

 

if i leave the battery in without cable connected to the guitar . The battery is fine. Once i hook my cable in my battery get hot . Could be the connector ??

 

my only suspect at this point is the preamp itself . Unless there is something i'm overlooking

 

no sound with or without battery , i replaced the battery because to test if the battery heat due to bad battery or something else
