Thanks guys,
It's a 2008 dyna and the service manual showes splicing both switches so I assume they knew something. I may try some contact cleaner first. Knock on wood it has been a great bike.
The switch part number is 71589-96B, so it's been around a long time (1996) and it's been revised at least twice as signified by that -B- in the part number. It's also obsolete since it doesn't come up as a current part number on the few dealer part sites I've tried it on.
I'd suggest testing the switch (power off, connect an ohm meter to the wires, and operate the switch several times, watching for continuity (zero resistance) in one position and infinite resistance in the other). If you had water in the switch a shot of contact cleaner could eliminate that (assuming you can get it actually into the switch), but that isn't going to keep it from happening again or fix a corroded contact. I'm not sure what Harley is telling customers who need a new switch, so you may want to ask your dealer, assuming they have a good parts guy who will take the time to find out versus just blow you off.
