Regulator

Hi has anyone had this problem with a 2008 Bonneville the eng mang light keeps throughing up p1108 promblam with volts volts were 13.5 to13.7/8 so got a scond hand regulator it was worse 13.5 to 13.6 so put the old one back disconect the head light i get constant 14volts so i can leave the bike for 2weeks starts no problem i have a new battery got rid of the pollution gear and by pased idear of telling the computer it cant start with the battery under 12vols so clear the code start the bike before i get out of the driveway the eng mag light is on does not affect the bike at all any idears or just don’t worry about thanks for any replies

 

EFI Bonneville Barometric preasure sensor trurns out after much reading and wasting money on a regulator it is voltage drop in this sensor honestly this eng mag light is more trouble than its worth

 

Pulled the plug on the sensor bit of contact cleaner ,blow out the little air pipe, back together. and no light on see how that goes
