Hey guys, I have a 2007 Polaris Scrambler 500 4x4 and I don't think that the vauum is working properly. I thought it was the fuel pump, but it still didn't start after I replaced the fuel pump. I also replaced the carb before because it was broken. The 2 wires that go to the fuel pump I thought were not working properly, but when I did more research it said that they were, and they were connecting to the right spots, but when I took the main wire off from the fuel pump to the carb I realized that the fuel wasn't coming out a lot. I think that the vacuum isn't working properly on the quad, but I don't know how to fix it. I heard that the vacuum is made from the engine, but I don't know how to fix it. Another problem is the battery, it dies out really quickly even if I am not turning the quad on. As long as the battery is connected to the quad it dies quickly. It's a brand new battery which I know is good. What do I do to see if their's a short somewhere, how do I test if the quad is taking too much of the battery?
