The solar panel charging is controlled via the Intellitec Batetry Charge Controller (BCC), which is in the battery compartment. It is a black box on the rear wall on the right. You can get a service manual for the BCC on the Intellitec web site - yours is a Model 800 like mine. It explains the functions of the BCC, including solar, and shows schematics as well.
There is no solar charge LED in a Tradition. Wish there was - I've though about adding one some day.
