Dear Friends .... Have an older 2000 Ford Coachman Catalina - 5.4 Triton Engine. Last year 2018 winterized it and began contemplating a Spring trip this year 2019.


Started it up today and the Charging System light came on an stayed on?

If you read the OP's posts carefully it seems he is NOT confused at all, he seems to clearly say that the CHASSIS started just fine, TWICE, but that the battery warning light came on after it started on it's own.

This would indicate that the CHASSIS battery is just fine, but that the COACH battery(s) are dead.

Once the relay or BIRD kicks in after start-up the dead coach battery connects and sets off the charge warning light because it can't tell what battery is low, just that the system is low.

Disconnect the coach battery or the charge relay and start the engine, I'll bet the light doesn't come on.

Even with everything off there are usually still a few small parasite draws on the battery.

After reading your posting .... This SC owes you and the others an update & to further clarify what happens. Initially when I go to turn/start & engage the key all indicator lights are on. After starting, the charging light stays on and does not go out. Hope this may help? Very much apologize for not clarify this initially.

If I can get out today I'll check this out further as you stated and see what we got? Thanks for the note, observations & suggestions.
