Illustration 14.
Motorola/Prestolite 6T-1395, 6T-1396, 7T-2095 and 7T-2096 Alternators.(1, 4) R terminal is an AC tap from the Stator.(2) B+ terminal.(3) B- terminal.Bosch, Denso (brushless), and Delco-Remy alternators contain three main external terminals: positive output, negative output and "R" terminals. Output for battery charging and for electrical accessories is taken from the positive terminal. The negative terminal is connected to ground. On many machines, the Electronic Monitoring System (EMS) is connected to the "R" terminal.
In some instances, an external power source is required to restore the residual magnetic field in the alternator. An explanation is in Service Magazine, July 7, 1986, "Brushless Alternators May Not Charge In Certain Conditions". This is accomplished by using the "R" terminal on Denso (brushless) and Delco-Remy and the D+ terminal on the Bosch alternator. Also, the "R" terminal may be used as an auxiliary terminal; for example, to power a tachometer.
The Motorola/Prestolite alternators shown in Illustration 14 are used primarily in truck, industrial and marine engine applications.
