940 L4-2.3L SOHC VIN 88 B230F (1992)
F8 Diode test
Select ohm x 10.
Diode resistance should be low in transit direction and high (infinite ohm) in blocking direction.
-
high resistance in both directions = open circuit
-
low resistance in both directions = short circuit
F9 Positive power diodes
Connect meter probes between B+ and diode terminals, one at a time (3 measurements). Swap probes and take 3 more measurements.
F10 Negative power diodes
Connect meter probes between D- and diode terminals, one at a time (3 measurements). Swap probes and take 3 more measurements.
F11 Exciter diodes
