Cobra 18 help
I bought myself a new toy 8) Any way I noticed the power cord has 3 wires instead of 2,( just red and black) like my cobra 19. These are Red, orange and black, the instructions are not very clear on what is what, so if anyone knows, please let me know.

My guess is that the orange is a power sense so the unit shuts off when it notices the key has been turned off.
You should be able to use just the red and black. You can wire it up to any 12v power source but if you want the CB to turn off when you shut the key off you need to tap into a power source that shuts off also or just remember to turn the CB off. In any event, the red and black will get you on the air. |
On the 18 the orange is a constant power supply wire so the radio so it maintains its memory. It should be connected to a power supply that is always on.

What Uturn said.
If your CB posts are always hot, you can hook both the red and orange wires to the red post. If it is key on only, you will have to find an always on power source for the orange, or the radio will loose it's memory every time you turn the truck off. |
I have Cobra with Bell Sti radar detector. It was working very good when I was driving for EH Jb hunt. Police still see me and give me ticket. :sad: I hire attorney and she marry me and we are move to Hungary. AH,I love american woman. :D

Oh ok. Still confuses me, but oh well. :lol:
Well, Steve, I am gonna bite my tongue on this one, too. I am not about to ask what Volatile means. :| |

Because, like most of todays am/fm automotive radios it is basically an electronically tuned radio. |

Volatile memory means it can't remember without power. Non Volatile retains it's information even after the power is turned off. Like your cell phone has a ton of this type of memory in it. You customize your phone and it remembers all your settings. With a cell phone, you need to keep battery usage at a minimum. As a side note. All cell phones within the past few years are using power even when they are turned off. The GPS tracking ability is always enabled so if your on the lamb, turning off your phone does no good, they can still track you. This was one of the last projects I worked on before trucking. |
Ahh, ok.
Makes sense. |
:D Ah, those CB radio questions bring back memories of my first CB radio. It was a Sharp 23-channel rig that could reach 20-25 miles and it was stock out of the box and I had a tall-ass, bumper mount super trooper antenna. It was back in 1974 or 75 I think! Oh those good 'ol CB days! 8)
