For the external alternator it shows the B+ as being connected directly to the battery, while the IG (and L) wires are disconnected when the master is turned off. The text notes that the integrated generator's regulator-rectifier must be disconnected to avoid running the battery down. The text does not mention any such requirement for the external alternator. Neither the text nor the diagram say whether or not relay 58 is supplied by Rotax with the engine. All this raises the following questions for this neophyte: 1. Is relay 58 included with the engine? 2. Does the external alternator need to be disconnected to avoid drawing down the battery? 3. What do the indicator lamps for each of the charging devices actually indicate? 4. Are the indicator lamps considered optional? 5. If installed, can the indicator lamps be LEDs? 6. Are the L and IG wires on the external alternator only for lighting the indicator lamp or do they serve some additional purpose? I know it's a lot of questions, but none of them seem to be answered in any of the Rotax documentation.
