Hey, I just scored a cheap Leslie 16 cab (which is basicly the same as a Fender Vibratone). Like most Leslies you see for sale it doesn't have the footswitch. No problem, I got the schematic from the web: https://schematicheavencom.secure.powweb.com/fenderamps/vibratone_16adapt.pdf I want to switch between the fast/slow setting. According to the schematic you have to short pins 2 and 4 of 'P1', like 'SW2' would without the cap acros the pins. When I do this I hear a humming sound (I think from the relay) and the motor stops. My question is: Am I doing something wrong? Or is the relay broken? Thanks.
