Dtjax Posted January 15 Report Share Posted January 15 Hello. I am a new user to the forum here. Thanks, in advance for any help you can offer. Yesterday, I had a battery (DTAP on a V-mount) short out. In my small kit, it feeds power to mixer (F8), (2x) lectro 411a and (1x) 401. When I plugged in the DTAP plug it sparked a little... so I stopped and did not fully insert the plug. The result is confusing to me... The 411's both will no longer power up by the power supply. The 401 is fine as well as the mixer. The 411's work fine and will power up by internal batteries no problem. If they are powered up on internal batteries and you plug in the power supply cable, they power down. You can remove the cable and they come right back on. Does anyone know what is going on? I read something on dipole protection for reversed polarity and it mentioned that the units would go into protection until the situation was remedied... Is there a reset function, blown fuse or something else. I have tried various combinations of power supplies, both through BDS and direct and the result is the same. Again, both units are acting exactly the same and work fine (power up, transmit and receive) on internal batteries. Thanks again for any advice.
