Battery, coolant, and brake light simultaneously.

Hi all.

Father-in-law was driving the van recently and called me to say all the above lights turned on all at once. Right away I thought "you broke a belt", but nope.

Belts are good. Alternator output is good. Coolant is good. Brake fluid and pressure are all good.

I'm thinking something failed in the warning system itself, maybe just a blown fuse.

Looking for a little direction on where to start the trouble shooting. Appreciate the help.

1988 van.

Grab yourself a fresh coffee (maybe a whole pot), enter "christmas lights" in the search field and settle in for a couple of hours of fun reading.
