FM transmitter question?

Did you wire it to the cigarette lighter wiring or somewhere else? If you have it on the accessories/on wiring, so that it is off when the car is off, battery drain is not an issue.

I suspect that after a 2 week vacation with the car parked in the long term lot, you'll need jumper cables to get the car started and since car batteries don't handle deep discharge, you'll be getting one of those, too. Why don't you just connect it on the accessory side of the power? Do you need it to function without the key?

As far as 'safe', do you have a fuse in the +12 line so if something shorts out, you don't start a fire or damage the wiring harness?

Dumb, dumb response. That sort of day....... rewire your tx so it runs off the cig. lighter, as I (sort of) implied.

Cheers.

I just disconnected the ciggerect wire harness and connected it to my transmitter. both my cigar plugs are always on even when the key is out. So it wont drain or cause any harm if its on with out the engine on for say 14 hours somtimes? also how do you just connect it to the accesorie power, please guide me through. thanks!

Wire it to one of the interior lamps. Of course you'll have to drive around with the door open. This is fine for the summer though.

Look down on the fuse block. Lots of cars have a power terminal there. ("fused Ign" or something like that) It really depends on the year, make and model of the car to get detailed advice.

Sweet all done! drilled a hole in the center consul, and istalled a hot LED switch connected both the sirius and the transmitter to the switch then soldered them! looking very good!

You have got a fuse in the 12V feed haven't you ?

well im using the cigar lighter power wires,and those are already on a fuse line, right?

I wouldn't know.

But you *should* !

Cigar lighter socket can provide some serious current so I suspect its fuse might out-live a short and rather burn another potentially weak spot in your wiring. It would be smart to use a small fuse. Thin Cu wire can literally burn when shorted over 12V which can burn you severely or do some damage to the car.
