GENTEXT/REMARKS/1. PURPOSE. THE PURPOSE OF THIS MAM IS TO NOTIFY ALL OPERATING FORCES OF REQUIREMENT TO DISCONNECT GENERATOR SET PSC WHEN GENERATOR IS STORED INDOORS OR IS COVERED IN ORDER TO PREVENT DEAD BATTERY. 2. BACKGROUND. REFS A THRU E ABOVE PROVIDE INSTRUCTIONS FOR INSTALLING PULSE SOLAR CHARGERS (PSC) ON USMC FLEET OF TACTICAL GENERATOR SETS TO PROLONG BATTERY LIFE. THE PSC IS DESIGNED TO MAINTAIN THE STATE OF CHARGE

(SOC) OF THE BATTERY; IT WILL NOT CHARGE A DEAD BATTERY. THE PULSE RECEPTACLE UNIT (PRU) ON THE PSC WILL PULSE THE BATTERY CONTINUOUSLY BY PULLING ENERGY FROM THE BATTERY. THIS PARASITIC DRAIN IS EASILY OFFSET BY THE CHARGE OUTPUT OF THE SOLAR PANEL WHEN THE GENERATOR IS OPERATED OR STORED IN SUNLIGHT. 3. ISSUE. SOME USING UNITS RECENTLY REPORTED DEAD BATTERIES ON GENERATORS WITH PSC INSTALLED THAT HAVE BEEN COVERED WITH A TARP TO PREVENT CORROSION. 4. ACTION. UNITS WITH PSC INSTALLED ON GENERATORS SHOULD ALWAYS DISCONNECT THE PSC WHEN THE GENERATOR IS SHADED FROM THE SUN, STORED INDOORS, OR COVERED WITH A TARP. LIMITED OR NO EXPOSURE TO THE SUN PREVENTS THE SOLAR PANEL FROM OFFSETTING THE PRU POWER DRAIN ON THE BATTERY AND DEEP DISCHARGE OF THE BATTERY WILL OCCUR, RESULTING IN A DEAD BATTERY. ADDITIONALLY, ACTIVE UNITS THAT NEED PSCMAY REQUEST THEM FROM MARCORLOGCOM POC'S LISTED BELOW OR BY ORDERING THEM: TACTICAL QUIET GENERATORS USE 24 VOLT PSC, NSN 6130-01-487-0035; THE MAGNUM MMG25 GENERATOR USES 12V PSC, NSN 6130-01-546-8432. RESERVE UNITS HAVE THE OPTION OF INSTALLING THE PSC WITH PUSH-TO-TEST ON TQGS, AVAILABLE FROM MARFORRES G-4 POC LISTED BELOW. 5. REQUEST WIDEST DISSEMINATION. 6. POC AT MARCORLOGCOM: MS.
