Re: Bypassing alarm system

Yes there are two sets of jumpers you need to do.

1. To get the bike running again you need to jumper the following pins on the 12 pin connector. Pin 3 (black/white/yellow) to pin 11 (black/yellow); this is the starter button signal to the starter relay.

2. Then jumper pin 10 (green/violet, switched power) to both pin 2 (Green, flasher module) and pin 6 (blue/violet, engine electronics relay). Now the bike will start and run normally and your flashers will work.

Go ahead and unplug the three pin connector to remove power from the alarm as often the internal battery shorts out and blows the fuse for alarm, horn, and brake lights.

Note these are the colors in the harness on the bike side not the alarm side.

Merry Christmas, all, while awaiting the arrival of my coolant hoses I am doing some odds and ends and decided disabling my alarm might be prudent even though I have it defaulting to not being on. Bike lives either in my garage or a shed behind a 12' iron gate system and I have two caliper locks with alarms for traveling so not sure the risk for of it getting stolen is worth the risk of an alarm malfunction. Plus I only have one fob and one drop could put me out of business, lol.

John I note these are for a 2005 on this thread but are they compatible later or earlier? Mine is 2003. Thanks for any advice. I might add I saw nothing under alarm or security in the Clymer.

An alternative is to just cut the insulation away on each of the jumpered wires and install a DPDT switch remotely so you "baypass" with the flip of the switch if you want to retain alarm function but bypass when it fails.

John I found corroboration, mostly, of your instructions for the 2005 likely working for my 2003 although the original poster had a 2002, lol.

In one you mention jump pin 10 to pin 6 AND pin 2 and then bike will start normally and "flashers will work".
In the other you just say pin 6 and then the bike will start and run normally. Is the last one for a normally working bike and the first one for flasher issues? Sorry for the confusion I have been trying to eke this out on my own.

Re: Bypassing alarm system

Don't add pin 2 to the 10/6 jumper. Your flashers will work without that. They made a change in 05 as to how they powered the flasher module. So just jump 10 and 6.
