how is that 20 sec delay better than just waiting for the spring-loaded key to go back to "ON" from "START" ?
If the house batteries are very low, it may be nice to have the engine settle back for a bit after a cold start before it's hit with that large charging load. But I don't know if it's actually any "better" or just my perception.
But if for some reason the chassis were placing a heavy load on the charging system and it dropped below 13.6, the charge relay would shed the house batteries to focus on the chassis. I can see value in that scenario, even though it is unlikely.
