INSTALLATIONS BY ALTERNATOR SERIES
6-SERIES ALTERNATORS
Six Series models are among the most frequently installed Balmar alternators. Designed to replace a wide range of
OEM alternators on most common marine gasoline or diesel engines, Alternators in the 6-Series family feature iso -
lated ground terminals (see grounding information on Page 3), Smart Ready
®
internal regulation, and a low-voltage,
low current D+ output that can be used to supply a dash lamp signal. 6-Series alternators feature three mounting
styles:
• 60-Series models, which feature a saddle mount with a 3.15" space between front and rear mounting feet.
• 621-Series models, which feature a single-foot (spindle) mount. These alternators include a 1" mounting foot
for Motorola-style engine applications, and a bushed 1" spacer, which allows the 621-Series to be installed on
engines requiring a 2" (Delco-style) single foot mount.
• 604-Series models, which feature a J-180, saddle mount with a 4" space between the front and rear mounting
feet.

1. (B+) Positive Output Terminal - Must be connected via properly-sized cable to the battery or batteries being
charged. Cable size is determined by alternator output and length of cable run. See Page 3 for wiring size chart.
2. Negative Terminal (Ground) - Must be connected to system ground via properly sized cable. Cable size is de -
termined by alternator output and length of cable run. See Page 3 for wiring size chart. Ensure that the ground
cable is adequately supported to supply strain relief .
3. (D+) Output - Provides a ground signal used in some systems to drive an Indicator or dash lamp.
4. Internal Regulator Voltage Sense Wire (RED) - Provides sensing voltage when the internal regulator is used.
This can be left on the B+ stud when not being used.
5. Dash Lamp Wire (BLUE - 60-Series only) - Included in the Yanmar-type T-plug. Typically not used.
6. Internal Regulator Excite Wire (BROWN) - Provides switched source of voltage to the alternator’s internal
regulator. Only connected when the internal regulator is being used. See diagram on Page 9.
7. External Field Wire (BLUE) - Connects to external voltage regulator via wiring harness.
8. Stator Output Wire (WHITE) - Provides an unrectified source of AC voltage which can be used as a signal for
an electric tachometer. The 6-Series alternator is a 12-pole alternator, meaning that the AC/Stator output will
provide 12 pulses per alternator revolution. In 24-volt systems, the Stator Wire will connect to the ORANGE wire
in the regulator wiring harness.
9. Alterntor Temp Sensor (Not shown) - The (Optional) MC-TS-A is typically mounted on the small stud on the
rear, side of the case, at approx the 10 o’clock position in the above drawings.
An unsupported cable may damage the positive or negative terminals, resulting in damage to alternator, regulator and wiring.
Ensure that cables are adequately supported to supply strain relief.
