2008 Street Glide Start Relay Gremlin
I have a mystery problem on my 2008 Street Glide. Original issue was no power to the stereo. I traced it to a blown start relay in the fuse panel (NOT the main starter relay under the seat). Audio and accessory power are run through the normally closed side of that relay so they are powered down during starting. I will get no power to the stereo randomly on occasion after startup, but the normally open side of the relay is fine, bike will still start as normal. What could be causing the accessory side of that relay to blow? Everything else seems to function normally.
Thanks,
J

Have you checked for anything else powered through the relay in question still having power? Does the headlight cut out during start and is it powered after start? If something else is powered , the relay is not the problem. As a general principle, everything made by man will eventually fail, have you replaced the relay if that is what you believe the problem to be?

I know that replacing the relay restores power to the stereo and accessory switch circuits. This has happened multiple times, so I'm confident in my diagnosis. What I want to know is what's causing it, so I can solve the real problem and stop replacing blown relays.

Back in the day when I had my 08 I was blowing P&A fuses. I eventually found where the rear brake switch wiring had been zip tied with a loop hanging down. The hanging loop would rub when the suspension went up and down during riding. Your issue is a relay so that wouldn’t be relevant though.

Rounders,
Relay will be fine one day, and the next, I'll start the bike and the stereo will have no power. If I shut the bike off, it will start again no problem, but the accessory power will still be dead, so the relay is latching normally, but doesn't reconnect the normally closed side when it un-latches. Is there power from startup that could be feeding back into the circuit somehow?

You need to get a print, you may need to look through the circuit for something not right. As they say, intermittent is tough.
Is what is picking up the coil the issue? Something energizes coil and contacts close, if open when de energized
Try to look in socket see if clean. If you can catch it when not working get a meter out.

You said everything else works properly isnt there other stuff thats cut (aside from the radio) when starting.
How confident are you that its not just the radio remote on internal switch failing? It wouldnt be the first time Ive heard on of those radios having problems.
