My brake light and battery light stay lit on my 1988 Pickup, 22r. In addition I was having problems with my choke, it took a good ten minutes driving to get it to turn off. I replaced the alternator, and my choke problem is fixed. Now my brake and battery light turns off initially then comes back on while driving, and cuts off and on. Any ideas?

Pls get a multi-meter, then read this for what to test and what to expect from a normally-functioning charging system for the 22R-E:
