No, but if there isn't an auxilliary relay in the circuit that powers the starter motor's solenoid (which itself engages both the drive gear and power direct from the battery to the starter motor proper), the solenoid is powered directly from the ignition switch, and that can overload the wiring if the starter is kept running for a significant time (say more than 20 seconds) and the start attempts get repeated with only short breaks in between. >The relay is directly on top of the starter, or in the starter or >whatever. The key only switches the relay on. The power to drive the >starter comes from the main positive lead coming directly off the >battery. It might be different in the 9000's but in the 900's the auxilliary relay wasn't a standard fitting in the early production years going on what I've observed in my own cars. Seems to have been a factory modification done later on.
