Hi, I'm new here. I have a 2000 Sportsman 500 HO that I bought used last year. I'd really like to get it back into top shape. It has a little over 3900 miles and 386 hours, which I thought were really low when I bought it.


Anyway, I have to get the battery tested for a no start condition for now cause that pull start sucks. In fooling with it, I found a loose vac hose that comes out from the bottom of the carb with a little red, round plastic (it says VAC on it) thing that has the vac line out of it then it just dangles. I looked for about an hour last night and coundn't find any open ports that it might connect to. Anyone have any ideas?

 

thats a one check valve for the "VENT" line, one end goes to the carb and other goes to nothing. just open.ones hooked the carb right? hope this helps. btw did you test the volts to the battery to see if the charging system is working? maybe why the batteries dead. just a thought.

 

yeah, one end is connected to the carb. I haven't checked to see if the system is charging. I'll connect the battery real quick and test it. I should just have to start it and see what volts it's getting with it running, right?
