Security light
Ok guys, lets see if anyone has the answer to this problem. I have a 07 Deuce with the security system on it. Lately, the security light in my speedo has been coming on while I'm riding the bike. It stays on for a while, then will go off briefly, then come back on and stay on for a while. I've tried to trace the wiring to see if there are any breaks or problems with no luck. Any suggestions. Also, sometimes, especially after I've been riding, I have to pull the clutch in to start the bike when it's in neutral. This has all happened since I changed over the the drag bars from Harley. Any help with this would be greatly appreciated.

But seriously, check the service manual, they have wiring diagrams and testing procedures. Might help you track down the problem.

Only more questions...
As Keno said "any DTC's" present? When you say the "security lamp comes on, then goes out", do you mean it enters the "alarm set" mode {flashing}? You may be experiencing a momentary loss of bus signal (ex: U1300, 1301, 1016, 1064, 1255) which will not shut down the bike while you are riding since it does not recognize this as a security breach and will allow you normal operation even after stopping. Basically means the TSM & ECM are not communicating at times: perplexing since this should be showing up as an engine light vice the security lamp, though. At least should show up as a speedometer fault code and may help to narrow down the problem. Or... if lamp stays ON, then goes out, without flashing then comes back on? Could be an security lamp circuit fault to ground: I don't have all wire colors but the circuit/pin connections are as follows: FROM the TSM/HFSM @ pin #3 TO speedometer pin #2, ALSO to ECM @ pin #5 and to the J-1850 @ pin # 3. The security lamp wire color should be Lt. green/violet, so all may be same color. From the TSM/HFSM pin #10 to the clutch switch to ground {BLK/R wire} so should be a simple enough closed/open check of switch and wiring (not familiar with "newer" bikes: they have these?) since you mention a start-up problem only in neutral. If you do not have fault codes, I would treat it as a simple security lamp wiring/connection problem vice a TSM/security problem (light comes ON when the circuit is GROUNDED). Hope this helped some anyways...
