Re: [MBZ] Red dash light for Battery is staying on

[Jim Cathey]

Now the light stays on while the key is on the off position and goes out

when key is the ready to start position.

It can't be the alternator, I'd say either the key switch
is shot (the electrical portion), or there's something
coupling battery power back into the ignition that oughtn't!
