No power to generator fuel lift pump

Hello all. Any thoughts on this. We are on a Hylas 54 #50 (2007)

Generator stopped today as we were making water in Guadeloupe. Fischer Panda Mimi 8. Usually this is due to filters so we changed the generator fuel filter and generator Racor. But generator would not start. So we began to investigate further. The auxiliary generator fuel lift pump connections looked a little corroded so we removed and cleaned them. But then we found there is no incoming voltage to the pump when the generator power circuit is activated. I assume This should be 12 v as soon as the generator main power switch is turned on under the chart table and the Fischer Panda panel power switch is activated. But nothing. Even with fuel supply open and lid of racor cracked there is no fuel flow. There is no labeled fuse for the generator fuel lift pump on the DC panel behind the chart table, nor apparently any in line fuse that we can find. Batteries are at full charge.

Any thoughts appreciated.

Re: No power to generator fuel lift pump

Iíd guess that there is a relay, hopefully one of those automotive 30 amp square ones, as they are easily sourced.
However to just get by for awhile I see no harm in unplugging the pump and powering it directly, just plug in before you start and donít forget to unplug after shutdown
