| Subject: | Understanding generator / alternator disconnect requirement |
The wiring diagram in the Rotax 914 installation manual shows the R,B+,L and C
wires from the integrated generator's regulator-rectifier are all disconnected,
via relay 58 when the master is turned off. 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.
