Bill Dennes Posted March 31, 2007 Share Posted March 31, 2007 When starting my '02 R1150RT the first time each day, it's important that it catch on the first try. If it does not start on the first try, the starter will not crank the engine anymore - instead it spins but does not kick the bendix out to engage the flywheel. The bike's voltage goes low pretty quickly, too from 12.6 or so down into the 11s. I'm chasing my tail around these possibilities: The starter is drawing too much current and sucking the battery down. The battery is not getting fully charged by the alternator. The battery is hurting. Note that I found a loose battery ground after having put 15k miles or so on this battery. It's a Westco with a black case, so cannot look for sulfation. My always-on clock/voltmeter is sucking the battery down overnight. The bike (and starter) has 89k miles. I've torn down the starter and lubed it several times. The voltmeter says 13.9 when the bike is running, and 12.6 after it's sat overnight. The bike starts happily and at once when it's really warmed up. BUT if I start the bike from cold and ride it a very short distance (say 1.5 miles) and then shut it off, it's almost certain that it will not crank again without a LOT of coaxing. Just spins the starter. One more thing, it'll start if it's jumped, but the car's engine must be running. When the jumpers are first connected, the car's engine RPM are dragged WAY down as the voltage on the bike comes up over 13. The car revs back up in a few seconds. Ideas? Can I buy a meter that clips over the starter's big lead like a timing light clip does? Can The Dealer run a test with their mega-tester and help me? Could the GS-911 help here? I'd prefer to spend money on tools instead of on labor. TIA! Link to comment
