Here is a Diagram of the Charge Circuit for the Onan B48G.
Make sure that there is a good ground to the V/R and that there is zero ohms resistance between the V/R case and the negative ( - ) battery terminal.
Using a VOM or DVM and with the motor at WOT or 3600 RPM's, (A) you should have 28VAC or better on the two white (or AC) wires. (B) Between Chassis Ground and the Gray (or B+) wire, you should have 13.6VDC or better
