No electrical power output
BAD CONNECTION BETWEEN ALTERNATOR AND REGULATOR
Insufficient wire sizing, damaged wires and poor connections can result in increased resistance. This may lead to burned
contacts / failure. Check wire, both connectors and replace if necessary
ALTERNATOR FAILURE
Both (30A and 50A) alternators are 3 phase AC generators.
How to check the 3 phases :
- Disconnect the 3 pin connector on the alternator wiring
- Run the engine (usual safety conditions apply)
- Carefully measure the voltage between wire 1 and 2 ; 1 and 3 ; 2 and 3 at different rpm
settings
- All values should be approximately the same at each setting:-
RPM
30A alternator
50A alternator
1000
+/- 23 v
+/- 17 v
2000
+/- 50 v
+/- 34,5 v
2900
+/- 65 v
+/- 52 v
Replace the alternator if not all 3 values are +/- equal
Regulator: no power output or voltage drop
23.05v AC
