STARTABILITY

TESTS

I

This is a top level test for problems with an engine that doesn’t start, or starts

but immediately stops, or is very hard to start. If the engine starts but

doesn’t

run well after starting, try the STARTABILITY tests first.

FOR THE ENGINE TO START, ALL OF THE BASIC SYSTEMS SHOWN BELOW

MUST BE WORKING.

THESE STARTABILITY TESTS WILL HELP YOU TO

VERIFY THE CONDITION OF EACH OF THESE SYSTEMS.
