I've posted on this previously but today after visiting my mate and looking at his LT I have a little more information. Hoping for some advice/opinions. The bike is fitted with a lead acid battery, not a Gel type of AGM. To me this is incorrect as the alternator won't charge it to 14.2 volts, which is what lead acid batteries need in order to be fully charged. I checked his alternator charging voltage at 3000 engine RPM and got 13.6, same as my '05. This tells me he should have either a Gel or and AGM battery. These batteries have different discharge characteristics then lead acid, so I'm tipping this is part of his problem. Now, the real problem - with the engine running I can hear a whine under the seat as if 1 brake servo is running continuously. Pressing the rear brake pedal causes a distinct sevo sound above the other one, to be heard. That all sounds fine. Pulling in the front brake lever I hear nothing different other than the continuously running servo (if that's what it is). The outer red brake warning light (far left) on the dash is flashing rapidly (4 Hz ?), the inner red light is glowing steadily. This is all with the bike sitting in the workshop and engine running. Too wet to test ride today unfortunately. Apart from the battery issue, which he is adament that it isn't a problem, I'm keen to hear what others think about the brake system problem. A dealer has previously told him he needs a new brake control module.
