'03 LT Sidestand Switch

Is there an up-switch contact to let the bike know the side kickstand is up? On several occasions, I have to tap it with my heel to start the bike. I can't find any contact when the stand is up

Yes. It's on the pivot pin of the stand. It is probably gunked up (technical term). If you get down under the bike you should be able to clean it well.

Or, you can do what I did and remove it all together. You'll have to inset a jumper in the connector under the left sidepanel to make the bike think it is up, but that's easy.

The switch is on the pivot point for the stand. It is circular with a PN 61 31 2 305 950 SWITCH, KICKSTAND - L=820MM $162.09

If you are having to kick it, it sounds like it needs to be replaced. I don't think it can be disassembled and cleaned.

Re: '03 LT Sidestand Switch

Hi , if you choose to eliminate the safety switch on your side stand, remember, it is there for a reason. I had a friend that had an aftermarket side stand on a Gold wing. With no safety switch on the stand he rode away with the stand down. That ride ended him up in the ditch,... a quadriplegic ...Not Good...

These switches have 3 wires in order to give a status for BOTH the UP or the DOWN position.
BMW has use the same switches on many models for many years with minor differences in color of a single wire.

With ignition OFF and the switch connector opened, you can test both UP and DOWN function for any intermittent problems using a simple OhmMeter function. Connector is located on left side (see attached photo number 1).

For the switch logic (continuity in various positions), see attached photo number 2:
Pin #1: WHITE wire (stand UP signal)
Pin #2: RED wire (stand DOWN signal)
Pin #3: BROWN wire (common ground)

There should be continuity between Brown and White wires (Pin 1 and 3) ONLY when side-stand is UP.
There should be continuity between Brown and Red wires (Pin 2 and 3) ONLY when side-stand is DOWN
.
OTHER NOTES:
(1) Female side of connector shown above is the side-stand side. The main wire harness side uses very delicate pins (male side of connector).

(2) When the side-stand connector is left unplugged (or a wire shorted), the starter interlock will remain active and the engine temperature light will stay OFF after ignition is tuned ON. In addition, the fuel-pump will not prime but the starter will still crank. Obviously the engine cannot be started in this state.

(3) From the main wire harness side, jump the Brown wire (Ground) and the White wire (Side-stand Up signal) to bypass the Side-Stand switch and allow the starter relay to start the bike.

(4) Starter safety interlock system uses 3 switches: Side-stand, Neutral, Clutch lever. In addition, if you have the optional Alarm/Immobilizer FOB, the starter safety interlock is also activated in certain conditions

You could see who's parting out a similar bike and get a used but functional replacement.

Early on I thought i had an issue with my side stand so I went ahead and bought one so i have it in my parts stash. Paid full price so no deal from me as I plan on keeping the bike for some time.

Re: '03 LT Sidestand Switch

Personally, I would advise to NOT eliminate the sidestand switch. My own technique for shutting the bike off in the garage, at the gas station, everywhere, is to put the sidestand down, verifying that the bike should not take a nap. I hate it when that happens.

+1 Glide up to the pump in first gear. Kick the stand down (kill the engine) and take up the slack before she goes on the stand. Safest way to do it.

Re: '03 LT Sidestand Switch

I have to agree, that the engine cutoff switch is there for a reason and thank you to those who offered their suggestions. Points well received,
I did remove the switch, cleaned it up a bit and lubed it with some silicon spray. As soon as the weather warms up I'll give it a try. If it still occurs, I'll replace. I guess the bike after 100,006 miles I got the use out of it.
