Section I. INTRODUCTION

7-1. Scope. Electrical systems on most POL equipment are 24 volt negative ground, direct current

systems. Electrical storage for starting and standby circuits is provided by batteries. The batteries

are connected in a series-parallel configuration to provide 24vDC current. In most of the larger POL

equipment, there are many safety circuits to prevent accidential damage to the equipment through

mechanical failure. For example, if the oil pressure drops too low, a safety circuit will shut down

the equipment.
