Relays (Fig. 19, 20)
To test a relay, disconnect the relay wire connector and
install a continuity tester between the relay terminals
(terminals 30 and 87). The relay should make and break
continuity at terminals 30 and 87 as 12 V.D.C. is con-
nected and disconnected to terminal 85 with terminal 86
connected to ground.
Resistance specifications:
Terminals 85 and 86 = 80 to 90 Ohms
Terminals 30 and 87a (normally closed) = continuity
Terminals 30 and 87 (normally open) = continuity when 12V
DC is applied to terminals 85 and 86

Battery
Use a hydrometer to test the battery. Charge the battery
if necessary (see Battery Service).
