I assume headlight is on? If not, you blew your main fuse. Although you said you checked your fuses. Also, my PO did his own wiring chop job. Found he had hard wired the main fuse out of the system. Thank god I found that and fixed it. I am not super experienced with the wiring, but check for power at the disconnects before the starter, but after the switch. When you say indicator lights you mean your oil light right? Again, I'd go through the wirin with a fine tooth comb. Make sure all your connections are in order. That's a must before you chase down any wiring gremlins. I may not be super proficient with 550 wiring but I was an aviation electrician for 5 years. I know the fundamentals. Whoever had my bike before did a horrible job with wiring and I spent a good while just undoig the weird stuff he did. It helped me tremendously when I had some electrical issues. Anyways, sorry if I wasn't terribly helpful. Hopefully one of the SOHC veterans can chime in and help. Also, was the "pop" sound like an electrical short sound? Or was it mechanical? Just might help in troubleshooting.
