9.0 TROUBLESHOOTING
Perform all tests at a test stand speed of 360 RPM with a 4-cycle test memory. The following tests
assume an adequate 12-24 Vdc power source and properly installed magnetic and Hall-effect pickups.
9.1 POWER MODULE - The following tests are to be performed with a known good Logic Module.
PROBLEM TEST TEST INDICATION CORRECTIVE ACTION (Figs. 3,4)
No output Section 4.1 Low voltage * Replace bottom power board (2).
One output Section Missing discharge Replace top power board (3).
does not fire 4.2/6.2 on stand or scope
Only one output Section Only one spark gap Replace top power board (3).
fires or fires 4.2/6.2 is firing
consistently
No Multi-Strike Section 6.3 Outputs do not Measure voltage at pin 10 of Vss of
function have four firings, 4- the ribbon cable on top power board.
5 milliseconds apart If voltage is 5V. in Multi-Strike mode,
replace top power board. If voltage
is 4V. or less, replace bottom power
board.
* Logic Module display will read LOW OUTPUT VOL TS ON A (or B) SIDE
(reference section 10.6 of CPU-2000 01).
**
Logic Module display will read PRIMARY FAULT (reference section 10.6 of CPU-2000 01).
9.2 LOGIC MODULE - The following tests are to be performed with a known good Output Module. The
tests assume a fully functional test stand.

*** May indicate a defective display or logic board.
CORRECTIVE ACTION (see
Fig. 2)
Replace logic board (9).
Assure keypad is plugged in to
display board. Replace keypad (2).
***
Replace logic board (9).
9.3 LOGIC MODULE DIAGNOSTICS MESSAGES - If any of the following diagnostic messages appear
when testing the Logic Module then replace the logic board.
A. GT PICKUP FAULT MISSING PULSES
B. RS PICKUP FAULT MISSING PULSES
C. HE PICKUP FAULT MISSING // NO-SYNC
D. RING-GEAR FAULT xxx TEETH READ where xxx is not equal to the number of teeth on the test
stand.
E. BOTTOM BOARD µP CHECKSUM FAILED
F.
