Morning guys
The Garmin, you can power through the USB connector, but it doesn't act the same as thru 12 V power. There are two cords. One with the traffic stuff and one without. You can always canibalize a cord and put on of the other ends that I reccomended. in fact, you should try to pick up a socket (the one with the lock) and a plug. The socket would have the waterproof cap. My list of devices might include:
This was the lead Im using however I cut this box out of the middle of it as Garmin said dora worked on 12v, so now it looks like this, although the socket has been moved to the other side to make room for my powerlet socket

Uses a ciggy charger 5v 1A supply lead
2. GPS - with/without traffic; th former is tough to deal with.
Al charger leads that have these pcb in ciggy socket seem to work on 12/24v, the 24v bit I dont need, so are they mainly to get steady voltage rather than spike suppressors
3. Cell phone - lots of charging issues depending on model. The only constant is change here.
iphone 3GS, again 5v 1A
4. Helmet headphone/mic system (Wireless/Wired?)
5. Short range communication receiver/transmitter
6. Audio/Radio
comes off direct 12v through this but radio will be powered seperately even though it plugs into this unit
so we basically have some 12v units, autocom, just mentioned,
oiler
Dora the expoler
Bluetooth module
then the camera & phone on 5v, as you can see even the oiler is electronic, so I had choice of a million connections to the battery or choose to put them somewhere out of the way, then the ciggy chargers are just too big & if there main function is so people can use them with 12/24v, I don't really need that part, however I would like the system to be interference free & protected.
Then the 5v side of things adaptable in case I ever change units, one power supply made right, using switchcraft sockets, if leads have to altered on the units then so be it
now to learn about AC
**broken link removed** just looking at sim CBB
This is going to be interesting, just noticed it is AC & DC, Ill knock sim up but then expect a million questions
**broken link removed**
Ok, Im restraining myself, sim up & running, I shall do the other bit first before asking

so your saying ther DC side of things, the waves runs 0.33v above the line like this, I'm still resisting bombarding you with questions until I've finished, apart from how are you measuring them, are you exporting data to get the graph like me or is there another way?

ok, first understanding:
DC & AC can run at the same time but Dc is on an elavated signal compared to running DC off a battery
questions from your sim:
