Antone got a manual for the Sterling Advanced 4 Step Alternator Regulator (Not the digital one) About 3 years old at a guess (IUoU+). Has a picture of the charging graph on the front case, about 100mm x 50mm, blue case cover with black heatsink and bottom. The website only has the latest manuals for download.
