<p>Apparatus for transferring power from the battery (256) of a service vehicle to the battery (258) of a second vehicle, wherein the final connection between the batteries is made from a remote location via a radio transmitter (80) and a receiver (270) which is mounted in the casing (22) of the apparatus to actuate a solenoid (72) in response to a signal from the transmitter (80). The circuit between the solenoid (72) and the receiver (270) includes a transistor (280) to control current through the solenoid coil (268) and the base of the transistor (280) is connected to the battery (258) of the second vehicle. Cables (28, 30) used to attach the apparatus to the second vehicle battery (258) are wound on a spool (26) having an interrupted ratchet (88) on one end thereof, the ratchet (88) engaging a ratchet lock (90) that pivots in one direction to hold the reel (24) when the reel (24) is turned in one direction to pay out the battery cables (28,30) and the ratchet lock (90) pivoting in the other direction within a ratchet wheel interruption to permit free rotation of the reel (24) in the opposite direction for retrieval of the cables (28, 30) on the reel (24).</p> |
