2005 Banshee – My key switch has 3 positions OFF – ON (just engine, brake lights, Turn signals, Speedo) ALL ON (Headlight, Running Lights)
Problem – when I turn to 1st click ON 2-3 seconds later brake lights come on (blink 3 times stay on solid) just like when pull right hand or foot pedal
Trouble shooting:
– Disconnected both brake switches checked if working correct – YES
– Called Cadent Technologies makes Smart Flash module was told to cut out box send to them and they could test but didn’t think it was their box They said “somehow” 12v was getting to Red wire on their module (I did not believe them) So before I completely removed the Smart Flash I cut the red wire expecting brake lights would still come on THEY DID NOT Cadent tech was right
– So I test the RED wire coming out of the frame from the switches and I am getting 9.36 Volts as soon as I turn key to 1st click and 2nd click (ALL ON) when I push foot pedal OR Right hand lever for front brakes I get 12.87 V same as at Battery
– ALSO the red light above the tag also comes on but gets brighter when I press or pull the brake pedal/leverQUESTION: How is 9.36 volts getting into the brake wire system?

EditorCheck your brake switch wire in the handlebars and the hot wire going to the hydraulic brake switch. Sounds like you’ve got a wire that’s grounded somewhere. Have you tested the hydraulic switch to see if it’s bad? Also, check all your turn signal sockets for corrosion or burned/melted spots. Sometimes they overheat and short out causing the running light circuit to back feed into the brake circuit. Kinda hard to diagnose without having the bike in front of me.

EditorIs the bike all stock as it was when it left the factory or have the lights been upgraded or switched to LED’s or has the harness been spliced into anywhere? Has there been an alarm added? Also, has there been any recent repairs done to the bike?

AdministratorAll is stock when I got it had only been used in Bike Shows for 3 years had 83 miles on it
All I added was a Battery Tender when I purchased it
I did have starter issues 3 years ago and that was the starter relay had rotted in the wire box
Nothing has been done lately, (last 3 years) this started this last season with only intermittent times
It’s the 9.36v and then full 12.87v when pedal/handle engaged that puzzles me. It apparently only takes a small amount of voltage to the smart flash unit to let it know you want brake lights on
I have disconnected all the wires from both switches and checked them and they work perfect
I would think if it shorted to the frame it would blow a fuse
This would mean a hot wire has rubbed against the brake wires somewhere and is bleeding power into the brake wires
I believe if anything was grounding out fuses would blow at least when I hit the lever or foot pedal and it made full power 12.87v
I have been careful not to let anyone touch this bike because of the issues others have had with mechanics
It is something a little electric tape or heat shrink will fix but finding the problem is the problem
All the wiring is like a girl in tight jeans looks like it was melted and poured in no slack in the wires at allloop-single-reply.php

True. 🙂

AdministratorFOUND IT
Switch in the right hand front brake lever is bad! Kaput! pressing and releasing creates different voltages at the SmartFlash module RED wire every time I press and release after several press and release it will even go to 0 volts (off)
Now where do I find a replacement for this little $2.00 bastard?

EditorAny HD shop can order it for you from the Drag Specialties 2014 Fat Book. Should be around page 876.

AdministratorNice find. The little gremlins are the worst. (and if you have someone else find it the most expensive.)

AdministratorYes, I spent 7-8 hours, a real mechanic with experience could have found sooner but we don’t have any of those in Atlanta,,, and when I checked this switch with tester I worked, because when I determined it really was the problem every 4 or 5 press and release it would work fine
I shot a little WD40 around the button and now it is working perfect every time, but I have ordered a new one because had to take throttle completely apart to get to this switch
The great thing is with whatever problems I have had with this Bike You still don’t have enough money to get me to part with it.loop-single-reply.php
