My 06 Mach Z will be sitting there and about every two minutes or so the warning lights will come and a error code of 10-9 will appear on the milage screen? I've tested the battery and its fine, the sled is charging the battery while running. What does this mean? It will do it so much that it draws the battery down to where it won't start and I have to charge it back up. Just went out for a 150 mile ride and had no problems, but having to disconnect the battery after every ride is going to get a little old!!!!!!!!!
