No probs Hoot, here ya go:
I've tried to clean it up as best i can, but hopefully you can see what i've done here. I've Frankensteined this thing from a few sources on this site...and made a few of my own changes...so hopefully it makes sense
Basically, the negative side of the battery is connected to the thrower light board/pack sound board and power socket through a SPDT (On-On) switch. The switch is either 'On' or 'Off/Charging'.
When it's ON the power can travel to the thrower board. However, the positive side of the battery goes: to the thrower - through the ACTIVATE switch - into the thrower board - and back to the sound board in the pack. This means that even when the master switch is ON the ACTIVATE switch controls the lights and power to the sound board.
When the switch is OFF the light and sound boards are effectively disconnected. The active connection is now through the charging port, so when it's plugged in i am ONLY charging the battery and the power isn't going anywhere else.
The VENT and INTENSIFY switches are wired up to the 'PowerUp' and 'Fire' connectors (respectively). This is another one of those reasons why i love the GBFans sound board. All you have to do here is connect a wire to a side of the switch in the thrower. I don't understand electronics enough to understand why, but it only works with a particular side of the switch. I had to cut the wire from the light board to the switch, attach my new wire from the sound board, and see if it works. If it doesn't just resolder it back the way it was and try again with the other wire from the switch.
I actually didn't decide to use the 'Song' switch, but that's just a simple connection from the board and through a switch (i was thinking of the spare thrower toggle).
By connecting the pack lights through the 'PACK' connectors means that they come on at the same time as the thrower lights.
Oh, and i'm using two 4 Ohm speakers. This just goes: SP- to 1st speaker negative, 1st speaker positive to second speaker negative, second speaker positive to SP+.
Hopefully this helps Hoot, just give me a shout if you want me to clarify anything
