Fusible Link and the Starter Motor

[patrickt]

1) Your starter motor will draw about 200 amps while cranking. BUT, it will have an initial draw of several hundred amps (my old style Ford FE starter motor has an initial inflow of over 900 amps).

2) If you were to place a fusible link(s) in your system, it would be between the source of potentially very high current (meaning your alternator or your battery) and the likely source of a serious fault to ground.

3) You do not need a fusible link on your system. I do not have a fusible link on my system. I have glass fuses on the eight basic circuits, a higher amp auto reset circuit breaker on the the positive cable after the starter solenoid; and a manual reset 15 amp circuit breaker on the headlight switch feed off the ignition switch.

4) You never place a fusible link on the starter motor.

Hope that helps.
