I have a foot switch for the K-250-4. It works the effects fine but I do not have any lights working. I have continuity from the center of the connection on the bulb to ground. I am not getting any voltage reading on that #2 pin. I even took a reading from inside the switch also when it was connected to the amp. I could not get a reading from red to ground. What kind of voltage should I be getting? AC or DC and what voltage? I have 2 of these amps with the same issue with no voltage to that xlr jack it seams? Seams strange. To get that xlr jack out you have to remove the reverb tank. Not a biggie but if I don't have to I would prefer not to. Any ideas?????
I found the problem. Red wire was disconnected from the connector and soldered elsewhere. Removed it and soldered it to the right pin and it is working just fine now. It is alive
