Normally-opsn tYPe:
1. Check for continuity between the terminals
. There should be continuity between the No. 1 and
No. 2 terminals when power and ground are con-
nected to the No. 3 and No 4terminals.
o There should be no continuity between the No 1
and No.2 terminals when power is disconnected'

Power Distribution Schematics
Power Distribution schematics show how power is supplied from the positive battery terminal to
various circuits in the car. Refer to the Power Distribution section to get a more detailed picture
of how power is supplied to the circuit you're working on.
From Battery to lgnition Switch, Fuses, and Relays
Individual circuit schematics begin with a fuse. The first half of Power Distribution, however,
shows the wiring "upstream" between the battery and the fuses.
