8. If battery voltage in step 5 above did not increase to
14.5 VDC and starter/generator tested correctly in step
7 above, test voltage regulator:
A. Set multimeter to VDC. Connect red (+) multime-
ter probe to the starter/generator terminal DF (Fig.
27). Connect black ( − ) multimeter probe to a known
good ground.
B. Start and run the engine at mid − range RPM.
C. The measured voltage should be approximately
2 VDC when the battery is charging and from 6 to 8
VDC when the battery is fully charged. This voltage
may rise to 14 VDC when the accelerator pedal is re-
leased and the engine is coasting to a stop.
D. If measured voltage is incorrect, stop engine and
replace voltage regulator. Retest charging circuit af-
ter replacing voltage regulator (Step 5 above).
9. When testing is complete, stop engine and remove
multimeter leads.
10.Install seat base assembly to vehicle.
11. Install rear frame panel cover to vehicle. Lower and
secure the cargo bed.
