Well the fast ticking is your solenoid and generally when they do that it is low voltage.Clean your cables and terminals thouroghly.check your battery water level.test batt voltage while running or bench test alternator if you haven´t found the problem yet check the fuseable link between the alternator and battery.If it´s gone replace correctly after you find out why it´s smoked.Some people run a jump wire around them but if you have a short you have no failsafe.I have thought about a circuit breaker but the best answer is fix it right.My bet is on a dirty cable causing a bad connection.
