Question about Connex 3300 240-channels Mobile Cb Radio Mosfet Powered
Was hooking up power to radio and noticed a spark when hooking up the ground wire the hot was already hooked up. shows complete circuit with ohm meter between the ground and hot
There is something shorted in the power supply. See if you can get a schematic from their website. Most likely parts to check are the voltage regulators, protection diodes and capacitors. A shorted diode will go to ground too.

The Connex radio is a division of Cobra, and no offense, but Cobras are one of the cheapest radios around. The problem with your Connex is a simple receiver malfunction. The receiver probably worked great until it was put into storage for a long time, you can replace the receiver, or you can fiddle around with the receive gain until you hear something. But you may just want to send it to a radio store and have it looked at, to be honest with you, Connex is a terrible radio, they sound good, but they're terrible radios. Go with Galaxy or Uniden radios, you won't be disappointed.

to cut down on noise i would hook it directly to the battery. make sure there is a fuse in the power cord first.
Please rate this solution thanks

I'm not sure if this will solve anything...but here it goes.
1st..Make sure you antenna connections are tight. it sound like it is arcing.
2nd.. make sure you SWR is very low. 1.5 or lower. (very important)
3rd.. make sure the rf power at your radio is turned down to low..over powering (over driving) your amp will fry your finals. (just as important)
If it's not any of these..then I'm not sure.
I have always used an Road King RK56. Not the knock off but the real deal. I would sometimes shock my lips on the metal grille , when I keyed up with my linear on high. I could also power flourescent lights when I got under them..lol and that was with a 250w box and a galaxy 99!
