Connect one
TEST LEAD to the - terminal and the other TEST LEAD
(3)
to the high
tension tower. (If the coil is Delco-Remy 1115282.
connect one
TEST LEAD to the case and the other to the SECONDARY
terminal.)
Typical coil secondary resistance readings are as
follows:
Manufacturer/part no.

Coil Secondary-To-Case Resistance.
Proceed as follows:
(1)
Set OHMMETER RANGE switch to 0-100K.
(2)
Connect TEST LEADS together, and using the ZERO ADJ OHM AND SERIES
RES control, adjust meter reading to zero ohms.
Connect one TEST LEAD to the case and the other to the high tension

(paragraph c).
a.
Initial Procedures.
Proceed as follows:
(1) Set FUNCTION stitch to OFF.
(2) If test is being performed on a coil mounted in the vehicle, dis-
connect the primary leads from + and - coil terminals and disconnect
secondary lead from coil tower. (If the coil is Delco-Remy 1115282,
disconnect connectors marked "-" and SECONDARY and remove the lead
attached with screw in the center of the coil.)
(3) Connect BAT LEADS to batteryas follows: Red +12 V lead to +
terminal and black -12 V lead to - terminal.
(4)
Set COIL CURRENT control to extreme counterclockwise position.
b. Coil Voltage Test (Prestolite-Autolite 115047, Delco-Remy 1915992, and
P&D Mfg. VC2X). See figure 2-4 and proceed as follows:
