New battery = loud alarm= no fob= HELP!

O.K. Good friend's 01 LT has developed an annoying (and had he found a hammer, near fatal) flaw. He can't shut the alarm off. OOPS!! The last time we planned on riding his battery was weak so he declined. He purchased a new battery (as I had months ago) and he dutifully installed it. But unlike mine, his bike's alarm started and wouldn't stop. For some reason I had zero problems and my alarm never went off on my LTC. He has called Lonestar in Austin and although friendly as usual they were not a lot of help at closing time Saturday and suggested he trailer it down on Tuesday. All fine and dandy but-we want to ride.

Rest of the story . Both he and I purchased our bikes used, mine is an 00. Neither of us received a key fob or pin with our bikes. I have looked through using the search function and Hall of Wisdom and I can't figure out what to tell him. I found one reference to bypassing the alarm completely, and one to paying $400 for an entire new alarm. Oh joy!

Anybody want to take a stab at it? I'd appreciate it a bunch and so would he. Thanks guys.

The alarm fuse is Number 3. Unfortunately, that's also for your horn and brake light! You may need to remove the tour trunk and disconnect the alarm system. Sounds a lot worse than it is. Getting to it is only a 10 minute job, the second time. 30 minutes, the first.

(Ignore my note regarding the radio fuse.)

Post No Instructions

I have alarm fob but do not have the instruction manual on how to operate it. The bike is a 03. Can anyone give brief instructions on how it operates.
I think it is turned off now hasn't went off. Got the bike used and no manuals with it.

My LT is an '03 so this should apply. Use reasonable caution. The fob you have may not be for your machine but if it turns the alarm on, it should also turn it off. You'll know if it dosen't do anything, you might want to start with a fresh battery in the fob.
There are 3 levels the alarm can be programed to, mine is the mid level and this applies, should yours be a lower or higher levels, well.......
With the bike parked and up on the center stand, depress the left button. The 4 way flasher should flash a couple of times and in about 30 seconds the little red LED on the right by the headlight adjust knob will flash, once every 10 seconds or so. Alarm is now armed. Should the bike be moved the alarm will sound (horn blows) and the 4 ways will flash for about 30 seconds and then reset, if it gets moved again, it'll do it again. The imobilized is also activated. This means you can't start it, even with the key if the alarm is armed.
To disarm (turn off) the alarm just depress the button on the fob and you should be good to go. The red LED wil stop flashing to indicate the alarm is off.
If you park the bike for an extended period of time (couple of weeks or more) with the alarm activated, it will be a good idea to have a trickle charger on to maintain the battery charge. It does use a small amount of battery to run it, enough to kill the battery in a couple of weeks, sooner if your battery is marginal.
I'm going to look for my manual for the alarm system and see about making you a copy. This is a sophisticated system and theres a lot more to it than what I can reasonably present here. No joy if the alarm system keeps you from starting it to get home.

If my friend hasn't found the big hammer yet, will the fuse "fix" or the "disconnect" the alarm "fix" render it rideable? i.e. will it allow it to start? because as the alarm was going off it was immobilized also. (Probably should have said that, huh?)

Any idea on why mine didn't react this way? Could the previous owner of my bike (who added many gadgets) have disabled the alarm/immobilizer function as was suggested in at least one post I found while searching? Or is the system different? Or should I play the lotto because I am a lucky SOB mine didn't react as his did?
