Just for ****s and jiggles I replaced the battery. 74 dollars of peace of mind.

In the end not sure what the magic ingredient was (probably a little of all three) but the truck starts better than it ever did.

Thanks everyone!

Hey there, I am having the same problem that you had.

FYI: it was raining for past 2 days, I was driving in the rain for a bit of both days. Next dry evening when it was warm and dry out, I had the S&M light turn on when I started up my 99 Disco2.

A/C has been broken for 3 years so I have not been using it. LR is winter car only.
Battery checked: 12.4 V (turned off)
Alternator checked: 14.4 V (turned on)
Checking all grounds pending:??????
Check XYZ switch planned:?????

Question on ground checking:
If I follow all the positive wires, every components connected to the positive, should have a ground????

Sorry for the dumb question but I want to waste less time as possible.

Any tips or advice on ground checking, I am hoping since it was raining out, the connection is corroded.

Thanks in advance!!!!!!
