I have a 2005 R1200ST that the fuel tank is not venting. At the connector plug I'm getting 12.75v (batt) voltage checking from hot wire to neg terminal on batt but only 10.6v to neg return(gnd) wire when bike is running. I've tapped neg return wire(gnd) and run that to batt. Solenoid valve opens now but is this safe for engine computer? Beemer BOB email is robertsonbmw@gmail.com Thanks
