Flasher Relay Buzzes, When on and when turn signal on Options

[hartpenn]

I'm restoring a 73 and finally vetting thru the electrical system before wiring her up for EV (electrical vehicle) mode. I've upgraded the fuse panel from JWest Engineering, it uses the SmartGlow big blade fuses, very nice. I've replaced the light switch and very carefully wired it back up. I also had to replace the steering column switch as it was cracked but very carefully wired it back up too.

Most wires are terminated correctly but some are not terminated at all but don't believe they contribute to this issue:
1 - Seat belt switch
2 - E-brake switch
3 - Brake switch
4 - Brake warning light switch

When I pull out the flasher switch, the flasher relay buzzes like crazy. It also buzzes when I turn on the turn signals. I initially thought the relay was bad, so I purchased a replacement and it does the same thing. I've even disconnected the flasher relay switch and hard-wired using jumpers and acheive the same results. One interesting note: when I jump 30 (non-switched power) to 49 (relay power A) and try to jump 33 (Gnd) to 49a (relay power B), it buzzes. 49 and 49a should just energize the relay, correct?

I thnk this smacks of a short somewhere, steering column switch maybe, cause its very tight in there for so many wires. I know I've made a lot of changes and thus very difficult to pin down but just thought I'd toss it out to the crowd. I've been stumped for days. Any suggestions would be highly appreciated.

Thanks,
Hart
