Electrical Issues 2005 K1200LT - Help please

In a previous thread I talked about having horn, radion, and HCS issues. Well I took the bike in to the bike shop for new tires and have all fluids done. I also asked the shop to look into what was going on with the three items. Well the shop called me and said they have traced the horn, brakelight, and HCS back to the same 10 amp fuse - but when a new fuse is installed it immediately pops. He is going to begin tracing the problem but doesn't have any ideal where the problem might be - has anyone experienced this problem and know where the fault is?

Cheers to all!

A fuse opening on a multi-branch circuit is going to require some troubleshooting, without ts no way of knowing the reason for the excess current. Does the fuse open without the key on, or when you turn the key on?

Disconnect the power lines for everything on that circuit, install a new fuse, hook up the power for only one of the items, turn the key on, power on the item. If the fuse is still good, move on to the next item.

If the fuse blows with nothing connected then you have a wiring short to frame/ground "somewhere". If it blows when a specific item is powered on well then you found the culprit.

But begin by disconnecting anything associated with that fuse and selectively reconnect them unless the fuse blows even with nothing connected.

Also check for a wire/ground short with an ohmmeter directly at the fuse with everything disconnected to confirm for a wire short.

The repair shop just called and said the alarm is out($400 to replace), which is causing the brake light and horn not to work. And the motor is out on the HCS which entire assembly is $1100. I'll have them replace the alarm module but I seen a few post on here where folks replaced the motor themselves just have to find the post that told what motor to use as replacement.

This is an awesome forum....

I am not familar with alarms but it sounds like they are covering all bases and replacing everything, that way they are bound to fix it, at your expense good luck hope they are right.

Motors for the EHCS are usually available from Global Direct but they seem to be out (last time they were $51.00). This place shows them available: http://www.stockers.com/index.php?dt=HS-50N


Sometimes the only thing wrong with the motor is the screw that grounds one of the brushes has become corroded. Fairly easy fix. Just hold the output gear lightly in a vise and remove the motor cover. You will see the corroded screw.

I ordered from DB Electric $59 shipped so happy with that. Next is getting the alarm replaced, the repair shop said he may have located a used one for $100 buck, we'll see.

The next thing will be to get the radio repaired (emailed Baris) waiting on a reply.

I just bought the bike last week from a one owner, and got a deal and it only has 36K miles on it. I don't mind putting a few bucks in it but really want to save where I can.

I had the EXCACT same problem in 2009 two days before an alaska trip. Freaked me out, scared of being stranded and going that far without brake lights. The dealer bypasses the fuse and smoke everywhere. Then said alarm ruined anyway. After replacing alarm (1600.00 not 400.00 they were "kind" enough to cannabalize a stock bike for part) its been fine ever since.
