By removing the fuse from #9 the amperage across the battery drops to 0.020 amps. Drop the fuse in and I can hear the siren try to sound but it just buzzes a bit and the sound goes away but the 0.180 Amp draw remains. For now, I just pulled the fuse, the car is garaged for the winter. Somebody posted step-by-step instructions to get to the siren and remove it. I'll do that next time we get 40+ degree Temps here in Connecticut.
Thanks to all for the input, the forum works!
