12.4.11.6 Check
Check of the ignition switch for presence of starter solenoid surge supresor diode (diode
assembly) and its installation, if missing.
General:
Check the ignition switch for presence of diode assembly located on starter relay, see Figure 12-49 and
12-52. If missing, install the diode assembly, P/N 16050-2 on starter relay in accordance with the
Figures. Particular external appearance of the relay can differ but the general method of installation
remains basically the same, i.e., the small ring terminal of the diode assembly (with red band near the
small terminal) is attached to the positive (starter switch) terminal of the solenoid coil of the starter relay
and the large ring terminal (with black cover on the diode lead at the terminal) is attached to ground.
For order of the diode assembly contact ACS Products Co.
Fig. 12-49.

28 Cruiser, as follows:
1. Cut off the part (small ring terminal) accordingly to Figure 12-49.
Fig 12-49.

TO THE IGNITION SWITCH DURING INSTALLATION OF THE DIODE
ASSEMBLY TO PREVENT THE ENGINE FROM FIRING IF THE
PROPELLER IS MOVED.
