Default choke and battery light staying on

Hi I'm new here. just bought a 1981 c3. last week the choke light and batter light came on and stayed on. The engine was running high idle and hot. After searching a few forums I learned that it might be a bad alt. So I had it checked and it was not working. I replaced it and everything was in working order. Now today the same thing happend as I was pulling it into a shop bay to have wheels balanced. Started it up and choke/batter lights stayed on. They checked the alt and it was putting out 19 volt and checked the battery while car was running and only 12 there. Could use some help in this area please.

The choke heater fuse is in the fuse block- left of the steering column on the firewall. Here's a link to a wiring diagram:

I like to print them as big as I can, then align all the wires, tape together and track the system I'm working with a highlighter.

IIRC, the choke relay is under the hood to the right of the distributor. (memory- may not be correct)

Get a 12v testlight, and check the brown wire that plugs into the alternator for power with the key on.
