My 06 Venture has had a fuel supply problem ever since I purchased it new. I replaced the fuel pump this past week, ( 3rd pump in 9 years) and rode the bike to work. It's 13 miles each way to work. Bike ran fine. Coming home, it was raining slightly. The bike was still running good fuel wise, but I did notice when pulling up behind a car at an intersection that the headlight was "strobing" for lack of a better word. I noticed the turn signal was flashing very rapidly, in time with the headlight strobing. Made my turn and continued on. The next thing I notice is the radio is not playing and the display is flashing off and on. Tried to turn the radio off as it acted like it was shorting out. Could not get it to turn off for about 1 minute. Finally it went off. 1/2 mile from home at a stop light the engine started to falter and died. When I tried to start it all I got was tick tick tick; the battery was too dead to start it. Towed it home and checked out the wiring. Thought possibly rain had gotten into the fairing and was grounding something out. Didn't find anything going to ground. Charged the battery and it holds a charge with no load on it. Used a jump box at first to start the engine. Voltage on jump box read 13 volts at start up. Turned the box off and the voltage dropped to 12.5, then with the engine running the voltage was dropping steadily as the engine ran. Engine ran about 2 minutes and was down to 10.6 volts when I turned it off. The battery is about 4 years old. I am wondering if I knocked something loose during the fuel pump replacement. Have also been reading posts on batteries, stators and regulator/ rectifiers. I'm lost at this point. Any advice and help will be greatly appreciated.
