Tohatsu MFS 30 [270/319] Inspection of rectifier
8-24
Electrical System
25/30 2006
Alternator (Charge Coil) Resistance : Reference Value (at 20°C)
Between Yellow (Y) and Yellow (Y) (three types)
0.29 to 0.43
7.Battery Charging System
1) Inspection of Alternator
1. Disconnect alternator coupler (3 pin).
2. Measure alternator resistance. Replace if other than
specified value.

1 Alternator (3 Pin) (Charge Coil)
2 Alternator (6 Pin) (Exciter Coil, ECU/Charge Coil)
This test can be made without removing parts.
2) Inspection of Rectifier
Check wire harness for disconnection of lead wire and
defective connection.
Check conductivity between each point by referring to the
following table. Value in ( ) is reference value.
Perform the measurement with all connections
disconnected to make the component a separated unit.

Note : 1 It is recommended to use "HIOKI HiTESTER MODEL 3030" for this measurement. Use of other instrument
model for the measurement can cause indication of abnormal value for normal condition, resulting in inaccurate
measurement.
2 Disconnect all connections, and measure as an independent unit.
3 Any movement of pointer indicates "ON" or "conductive" state.
4 "CON" means that the pointer moves once and then returned to the value shown in ( ) because of characteristic
of capacitor.
5
The value in ( ) is the condition applied when "1k" range is used. The measurement varies widely among types
of instrument, situations (such as inner power supply), or measurement ranges due to diodes used in the unit.
Measurement Conditions : Type of Circuit Tester : HIOKI3030
• Measurement Range : 1k
• Permissible Error of Resistance : ±20%
•: The resistance values may vary widely
among circuit testers because of their error
characteristics.
CON
This test can be made without removing parts.
"ON" means "conductive", and "OFF" means "non-conductive".
