N O T E
This procedure may be performed with either a digital or analog multimeter.
Step 5. Check condenser as follows:
a. Turn engine over so that breaker points (para. 4-30, figure 4-21) are in open position.
b. Connect positive lead of multimeter to condenser terminal lead.
c. Set multimeter to highest resistance setting and zero meter.
d. Connect second lead of multimeter to ground while observing meter.
If meter shows a deflection, then goes to infinity, then go to next step.
If no deflection occurs, or does not go to infinity after deflection, replace condenser
(para. 4-31).
If meter doesnt return to infinity, remove connection between points and condenser and
retest. If deflection occurs, replace points (para. 4-29).
