Rob -
Couple suggestions for narrowing down the issue.
As rwven suggested, watch for the CB symbol on the status line at the bottom of the screen.
Verify what channel the CB is set to (losing standby power when fuse was pulled may change the channel).
Check the CC switch on the right to confirm the software hasn't reverted to the oem configuration.
Check the PTT switch on the left to confirm the CB does/doesn't chnage the CB symbol status.
Check the passenger PTT switch (push in on front button on right speaker pod).
The channel selected could be the issue: sometimes a strong signal will wash out the receiver & you'll hear the other person even when on different channels.
If CB symbol status changes from on to transmit mode when any PTT switch depressed, the CB should be working.
If none of the PTT switch checks changes the CB symbol status, I would consider doing a radio reset & try everything again. NOTE - the radio reset will delete all presets in the radio.
If all this fails, might be time for a visit to the dealer?
Sorry. Little slow in responding. Post #3 was up before I finished typing.

The CB symbol is visible on the bottom of the screen but does not light up when I press the FRONT PTT button. I had the CB set on Ch. 19 today but first discovered the problem when on a group ride and we were all tuned to Ch. 2, I could hear everyone but could not transmit. The CC is still active on the right side switch pack and is functional, I used it today and all the functions work, on/off, accelerate/slow. As to the passenger PTT, I checked this (great call) today and the CB symbol DID light up when I pressed it. I tried to talk and could hear the "back tone" ( I don't know the exact name) so it seems like the rear button is working. Now that rear (passenger) PTT button is only for the intercom, correct? The passenger couldn't push that button and talk on the CB, could they? And I still have no way of adjusting the squelch so I still don't know where that setting is.
I stopped by the dealer today and tried to pick his brain a little. He suggested updating the software to the latest version (I'm at 120.3.1 now) and seeing if that works. I think I'll try the system (radio) reset first and if that doesn't work I'll do a software update, I can always revert back to the 120.3. I'll try that tomorrow, THANK YOU and I'll let you all know how it goes.

Thanks Dave, the problem I have pulling that master fuse is that every time I do it the damn siren goes off, even when I pulled it yesterday I could only keep it out for a few seconds as the siren was blaring. I guess the siren has some kind of battery backup in it to prevent messing with the bikes power system. Even when I changed the battery after a few seconds of the battery being disconnected the siren went off. Maybe I can fully disconnect the plug to the siren and that MIGHT work although the siren might sense a power interrupt and go off. I'll try to mess with that tomorrow too...

The passenger PTT does operate the CB.
We were on a ride and our lead lost his CB - he could hear us- but we could not hear him. He relayed his messages by his wife (on the back)

I just checked my '14 FLHTK. Without any headset plugged in, the CB indicator will light up when either the rider or passenger PTT switch are pushed. I also turned on the Intercom (again without any headsets connected) and both the INT & CB indictors will light up when either PTT switch is pushed. With the Intercom ON and the CB OFF, the INT indicator will light up when either PTT switch is pushed. I have the original switches (not lighted) and I did NOT have the Cruise & PTT switched.

O.K., tomorrow I'm going out for a ride. I'll stop by the Expressway and try t transmit from the rear jack over the CB, plenty of truckers going by so someone should hear me. Do you know if you can adjust the squelch from the rear buttons, that would at least give me some idea where it is set at.

If I had to guess I'd guess that the canbus has lost the address for that switch somehow. Changing the battery shouldn't do that but it's the only suspect at this point. I took a look at the CB chapter in the BoomBox manual and there are no settings that affect the transmit functions that I could find..

I'm not absolutely sure of this, but I think you can push the passenger's PTT and talk from the rider's headset. You cannot adjust the squelch from the passenger controls so, depending on your present setting, you may not be able to hear CBs that aren't close by. If you are at a truck stop transmitting on Channel 19 you should have a trucker close enough to talk to as you could hear other CBs previously.

I just tried but I can't adjust the squelch with the passenger PTT switch. The passenger PTT switch is labeled Vol up & down & PTT. Moving the passenger PTT switch up/down changes the rear (passenger) headset volume according to the radio display.
I see I'm late again, didn't see rwven's post.

O.K., a strange (but welcome) solution to this strange problem. Took a ride this morning, nothing had changed. I plugged the headset into the front jack and pressed the rear PTT button and the CB button lights up so I'm thinking the CB is O.K. it must be some kind of software issue. I get home and try the system reset, I tried all 3 options and no change (other than losing my pre-set radio stations and some settings), still no response from the front PTT button. So as a last resort I updated the software to a newer version, I had a 121.4 ( I think) in the bag on a flash drive, I grabbed that. Updated the software and the PTT button started working, great. I couldn't talk to anyone, no one in the area I guess but the CB icon light up and the squelch worked. So I'm thinking if I lost something when I changed the battery it seems like I now got it back. So I now try to downgrade back to the 120.3.1 version (my preference), I go through the downgrade and the PTT button is not working, WTH?? So as a last resort I just downloaded the latest Boom software version (122.1.xxx?) and installed it and the CB seems to be working fine, I guess time will tell. I'll try this software version and hopefully it will be O.K., if not I'll mess with the system a little more and see if I can get back to the 120.3. A BIG thank you to all for your input and suggestions, it's really appreciated...have a great Memorial Day!
