The Serial Port Test
This test verifies that the RS 232 port used for linking to commercial entertain-
ment systems is working. You must have the loop-back cable assembly, pn
040051-001 to perform this test.
1. Insert the loop-back cable assembly into the RS 232 port on the back
of the console.
2. Press [ LEVEL: ^ ], [ 6 ], [ 2 ], [ENTER]. The console will display “C.S.A.F.E.
TEST.” Press [ENTER] a second time.
3. The console will run a diagnostic test and then display either “PASS”
or “FAIL”. Replace the console if it fails this test.
The Alternator Test
Use this test to verify the alternator field routines of the console. You will need
to briefly exercise on the machine for this test.
1. Press [ LEVEL: ^ ], [ 6 ], [ 3 ], [ENTER] to start the test.
2. For “Field on” press [ LEVEL: ^]. Step on the machine for
approximately 10 to 15 seconds. If full resistance is achieved during
this time, your console has correct current flow. If no resistance is
achieved, either the console or the alternator is bad. See the
electrical troubleshooting portion of this manual to isolate and test
the alternator. Replace the console if the alternator is good.
3. For ‘Field off” press [ LEVEL: V]. Step on the machine for
approximately 10 to 15 seconds. You should not get resistance with
the field turned off. Press [CLEAR] to end the test.
