Re: Starter not cranking
Welcome to the forum.
If you have the new upgraded blue relay ( not standard on a 99) , it has a low voltage cut out that will prevent starter engagement with a low battery protecting the relay from fusing due to excessive current from the low voltage and slow turning starter which is pretty much a dead short. First thing I would do is check your battery is fully charged and provides over 11.5 preferably higher in the 12v + range with the key on not running. If it is lower than that, the bike will not crank. Replace the battery then, it is toast. If the battery remains over 12V and still does not crank, it is rare but the relay circuitry may be bad so you might have to replace it.
Some have put in the old style Ford fender relay to replace either type. Be careful where you mount something like that because the metal mounting bracket on those is often tied to one of the small posts for ground and single wire operation so it may matter which one you connect to for the actuating wire.
