CURRENT LIMITER CHECK
1. If Both DC GEN annunciators are illuminated –
Individually press each volt/loadmeter switch and
observe voltage. If generator voltage is not seen
on voltmeter, that current limiter has burned open.
2. If one DC GEN annunciator is illuminated – Press
both volt/loadmeter switches and observe voltage.
If generator voltage is not seen on the affected
side, one or more current limiters have burned
open. If battery voltage is not seen on the
affected side, the current limiter for that side has
burned open.
