How is battery current limiter work ?
I try to diagnostic the issue of delay when engine starts.
Basically I can see the positive terminal connect to the limiter then limiter connect to alternator + starter. Also a sensor is inside of the limiter.
I wonder if the limiter fails will lead to no battery charge and cannot start engine ?
It seem like both alternator and starter connect to battery via the limiter. However the alternator also has voltage regulator why it still need the limiter ?
90 is the limiter
420 is cable which connect to alternator and starter.

That looks like a high amperage fusible link. It is there to protect the vehicle from a battery short circuit that could start a fire. I have them on my boat between the batteries and the engine. Not sure it would have anything to do with delayed starting.
