AD/CESSNA 206/26 Ammeter Type and Position 9/78

Applicability: All models.

Requirement: 1. Inspect aircraft to ascertain if the ammeter has been modified in accordance with Rex Drawing RA-A-1109 or if a centre zero ammeter (charge/discharge type) is connected in the alternator line.

2. Reconnect centre zero ammeter (charge/discharge type) into the battery line in accordance with original Cessna wiring diagrams.

Note: This requirement can be quickly checked by switching on the battery master switch (alternator not running) and a load such as a landing light switch and noting the following:

if ammeter reads below zero in the discharge sector then it is connected in the battery line.

b. if the ammeter still reads zero when a load is applied it is quite possibly connected in the alternator line and needs to be reconnected into the battery line.

Compliance: Within the next 100 hours time in service after 30 September 1978.
