Briggs & Stratton 076000NG Service & Troubleshooting Manual page 27

trickle charge output, a fully charged battery
must be installed in order to turn the trickle
charge on.
1. Set SYSTEM switch to OFF.
2. Remove the 15 Amp fuse from the system
contol panel.
3. Inspect the fuse to see if blown.
• If fuse is good, proceed to Step 4.
• A blown fuse indicates a short in the
circuit. Repair any short and replace
fuse before proceeding to Step 4.
4. Disconnect the negative (-) battery cable.
5. Disconnect the positive (+) battery cable
from the starter motor.
6. Isolate Wire #13 (small wire) from the
positive (+) battery cable (Figure 8).Do not
allow Wire #13 to touch ground.
Figure 8
7. Reconnect negative (-) battery cable to
negative battery terminal.
8. Ensure UTILITY voltage is turned ON.
9. Reinstall 15 Amp control panel fuse.
10. Set the meter to measure DC voltage.
Connect positive (+) meter test lead to
Wire #13. Connect negative (-) meter test
lead to negative (-) battery terminal.
11. While observing the meter and keeping
the positive (+) meter test lead connected
to Wire #13, momentarily touch Wire #13
and meter test lead to the positive (+)
battery cable, then remove (Figure 9). This
will turn on the trickle charger long enough
to read the trickle charge output voltage
on the meter.
Figure 9
12. About 13.5 VDC should be measured
when the wire is removed from the post.
The trickle charge voltage will diminish
quickly.
• If no voltage is measured, proceed to
TEST 3 - Check 50 Amp Battery
Fuse.
• If voltage is measured, the trickle
charger is functioning. Reconnect all
wiring, return the unit to standby mode
and reset the exercise timer.
