11. Install the FL fuse (1) to the fuse and relay box (2).
12. Evaluate the compression tests:
^
Normal operation: If the cylinder compression pressure increases quickly and evenly to the compression standard [1,400 kPa (199 psi) at 250
RPM], the pistons, piston rings and the valves are operating normally.
^
Piston rings faulty: If the cylinder compression is low on the first stroke and tends to increase on the following strokes (but does not reach the
compression standard), the probable cause is that the piston rings are faulty. The addition of oil should improve the compression pressure
considerably.
^
Valves faulty: If the cylinder compression is low on the first stroke and does not increase on following strokes, the probable cause is that the
valves are faulty. The addition of oil does not significantly improve the compression pressure.
