Charging System Quandry

[Electro12WH 50]

I have a K341 engine that purportedly came out of a Genset. It has no markings, no tags, no serial numbers. What I need to know is the rectifier to use. Can I use a multimeter to measure the amperage output and go from there? It has two wires coming from the stator, therefore it is most likely a 10 or 15 amp. system.

You would do yourself a big favor by downloading the service manual available as a free download. These manuals have wiring diagrams and identification information to help you with your task at hand.
