BREAKOUT BOX: EFI
5.7
GENERAL
f2377x8x
The BREAKOUT BOX (Part No. HD-43876) splices into the
main harness. Used in conjunction with a DVOM, it allows cir-
cuit diagnosis of wiring harness and connections without hav-
ing to probe with sharp objects.
NOTE
See wiring diagrams for ECM terminal functions.
INSTALLATION
1.
Remove right saddlebag and side cover. See Figure 5-
10.
2.
Depress latch and remove connector [78B] to release
EFI harness from ECM.
3.
Install connectors on Breakout Box to ECM and EFI har-

REMOVAL
1.
Separate connectors to remove Breakout Box between
ECM and EFI harness.
2.
Install connector [78B] to connect EFI harness to ECM.
3.
Install right side cover and saddlebag.

WIGGLE TEST
5.8
GENERAL
hd39978
The wiggle test indicates the presence of intermittents in a
wiring harness.
PROCEDURE
1.
See Figure 5-12. Connect DVOM (Part No. HD-39978) to
wiring harness between the suspect connections. When
diagnosing ECM connections, use a BREAKOUT BOX
(Part No. HD-43876) to simplify the procedure. See Sec-
tion 5.7 BREAKOUT BOX: EFI.
Figure 5-12. Fluke 78 Multimeter (DVOM)
(Part No. HD-39978)
2.
Set DVOM to read voltage changes.
3.
Start motorcycle engine and run at idle.
4.
Shake or wiggle harness to detect intermittents. If inter-
mittents are present, radical voltage changes will register
on the DVOM.

1DANGER
Propane is an extremely flammable liquid and vapor.
Vapor may cause flash fire. Keep away from heat, sparks
and flame. Keep container closed. Use only with ade-
quate ventilation. Failure to follow this alert can result in
death or serious injury.
1WARNING
Read all directions and warnings on propane bottle. Fail-
ure to follow all directions and warnings on bottle could
result in death or serious injury.

1DANGER
Propane is an extremely flammable liquid and vapor.
Vapor may cause flash fire. Keep away from heat, sparks
and flame. Keep container closed. Use only with ade-
quate ventilation.
Figure 5-15. Checking for Leaks
NOTE
Do not direct propane stream toward front of engine. If pro-
pane enters air cleaner, a false reading will be obtained.
4.
See Figure 5-15. Aim nozzle toward possible sources of
leak such as fuel injectors and intake tract.
5.
See Figure 5-14. Push valve (4) to release propane.
Tone of engine will change when propane enters source
of leak.

DIAGNOSTICS
Diagnostic Notes
The reference numbers below correlate with the circled num-
bers on the Test 5.10 flow charts.

1.
Check for trouble codes. See RETRIEVING DIAGNOS-
TIC TROUBLE CODES under Section
5.4 CHECKING
FOR DIAGNOSTIC TROUBLE CODES: EFI.

2.
Check the condition of the battery. Perform a voltage test
and recharge if below 12.60V. Check battery connections
and perform load test. Replace the battery if necessary.
See BATTERY in the Touring Service Manual.
3.
Connect BREAKOUT BOX (Part No. HD-43876). See
Section 5.7 BREAKOUT BOX: EFI.
4.
Remove spark plug cable from spark plug.
a. Visually check condition of plug.
b. See Figure 5-16. Attach cable to SPARK TESTER
(Part No. HD-26792). Clip tester to cylinder head
bolt.
c. While cranking engine, look for spark. Repeat pro-
cedure on other spark plug cables.
Figure 5-17. Ignition Coil Circuit Test
NOTE
Engine will not spark with both spark plugs removed. When
checking for spark, use SPARK TESTER (Part No. HD-
26792) with both plugs installed.

Diagnostic Trouble Codes U1300, U1301 or

See Figure 5-22. The typical serial data voltage range is 0
volts (inactive) to 7 volts (active). Due to the short pulse, volt-
ages will be much lower on a DVOM. In analog mode, a
DVOM reading serial data will show continuous voltage when
active, typically 0.6-0.8 volts. The range for acceptable opera-
tions is greater than 0 and less than 7.0 volts.

Problems in the fuel system or IAC system may also create
this symptom.
