I am trying to trouble shoot a battery or electrical problem. Fully charged, I am measuring 13 volts on my battery, but it doesnÔÇÖt crank my engine. My BMW charger lights do not indicate any battery faults.
One trouble shooting tip that IÔÇÖve seen is to check the amps between the negative post and the ground wire with the positive side connected. This is suppose to be less than 2.0 milliamps and IÔÇÖm getting 2.8 to 3.0 milliamps. Should an extra milliamp be a problem? Even so, a fully charged battery should crank the engine right?
I replaced the battery 1 1/2 years ago with a BMW battery. This is an expensive battery, but the first one lasted 5 years and at the time I was figuring for that kind of life it was worth the extra $. I really donÔÇÖt know if its the battery or my electrical system.
Before the this issue, the only electrical component that is not working on my bike were the heated grips; otherwise everything on my ÔÇÖ04 R1150RT was working fine.
