masonmike - I'm sorry to hear about the issue. Looking at the fuse block schematic, it looks like the Aux powerlet and the radio share the same fuse (#21). Have you checked that fuse? At 15amps, I'd suspect it would go before the big 100amp mains.

I'll look at the schematic in my service manual tomorrow. To be more correct...Fuse #21 will supply 12VDC to to the Accessory "Relay". When you turn the Key to ON or ACC the relay is closed allowing 12VDC to the radio, the ACC Terminals via fuse #6, AND anything else Honda considers accessory. (I'm not saying there is any other "accessory", I just don't know.)
The part in the OP's description that worries me is the clock not working. 12VDC must be available all the time to keep the clock working. The voltage won't come from the accessory relay and won't be switched on and off with the key.
I would start by checking each installed fuse in the Fuse box. sometimes fuses fail but you can't see it visually. If you don't have a cheap $10 multimeter, buy one at an Autoparts store.
1. Turn the Key to ON.
2. Set the multimeter to 12V or higher "DC" not AC. You should see a "V" on the dial somewhere with "DC" or straight lines and not a tilde "~" wavy line. Each meter is different.
3. To test the multimeter, You should ALWAYS get 12VDC if you touch EITHER side of a good fuse with the RED lead and touch the bottom (-) terminal of the ACC Terminal with the Black lead.
4. Touch both multimeter lead tip to the exposed metal on EACH side of EACH fuse. It doesn't matter which side is touched with which Red/Black lead.
5. If you get NO reading the fuse is good...Or "shorted" and not dropping voltage. If it's open/blown you will see 12VDC (Red/Black correct) or -12VDC (Red/Black reversed). Again your just looking for any voltage reading.

SeaSteve - I agree with systematically testing all fuses as you've recommended.
You're absolutely correct regarding fuse 6 feeding that ACC relay, which then feeds ACC term via fuse 6. I suspected fuse 21, since OP also noted that he lost his audio system, and the ACC relay fed by fuse 21 feeds both. My copy of the manual is from a Full Wing, but I attached the page I think you're referring to below, sir.
Now that you mention that OP also lost his clock, and that it's constant (non-switched) 12v, I'm beginning to suspect fuse 22. According to the fuse map in my copy of the manual (2nd screen cap below) that is the constant 12v supply to the clock. I agree, though, that checking all fuses is a good next step.
Kind Regards.

Thanks for all your interest and the many suggestions guys. We have electrical engineers on this forum, good to know. Surprised by all the attention this thread was getting, I decided to take the suggestion and carefully double check the fuse box. By the way, the fuse box diagram sent does't resemble mine in the least. I have at least 8 empty spaces. That being said, when initially checking out the problem, I must have put the fuse for the clock back in the wrong spot. Behold!!! Now the clock works, as well as the radio! Yet, the radio has it's own separate fuse, which was perfectly fine. Another mystery? Problem solved! It was probably the reset by disconnecting the battery, that initially resolved the problem. Those damn gremlins! I'm sorry the solution wasn't more technical. Yes, I feel like an dummy, but a very happy dummy. Thanks again for all your interest.

Good job, and thanks for the follow up! Which fuse was that that controlled the clock? TIAOriginally Posted by masonmike

I'd have to get back to you on the number. I recall 3rd from the bottom on the right side column. Could have been #29. I still find it odd that the radio, intercom and USB port would not function at all without the clock fuse in place. As well the clock would keep time only while the bike was running. Whenever I turned off the ignition, the clock would reset back to 1:00. I find it odd that the clock and radio would share their function on two separate circuits. I'm sure there is a logical reason why Honda has done this. Again guys, thanks for your interest, very much appreciated.

Glad you got it fixed and it wasn't a bigger and expensive problem. (DOH!I completely forgot to look at my service manual yesterday.) You've learned electronics rule number one: It's usually the last thing somebody messed with!
Probably the fuse box shape and SOME of the fuses are the same. Obviously different models have different electrical circuits and fuses but the layout is usually close. The "clock" fuse will be constantly powered so the clock keeps time when the key is off. Probably, that same 12VDC is needed to keep the radio stations memory the AUX USB selection, and individual audio settings stored. Must also be something beyond those needs to operate the radio. The ACC/Audio fuse is keyed through the ACC relay.

Just for future reference: Here is a diagram from my manual for a 2013 F6B. Maybe this is like yours? Fuse #29 is labeled "CLOCK FUSE". I should have simply looked at the label vs the schematics.

Thanks 98 Valk, yes that is my fuse box and yes I agree, the label is far easier to read than the schematics. Still I managed to put the fuse for the clock in the wrong spot... UGH!!!Just for future reference: Here is a diagram from my manual for a 2013 F6B. Maybe this is like yours? Fuse #29 is labeled "CLOCK FUSE". I should have simply looked at the label vs the schematics.

I can only say, that will be less likely to happen again.

BOY, Thank God I've never done something as stupid as that! (wink,wink) Be there, do that but I didn't have to post it on a public forum when I did.
