10.1General

Work on electrical circuits should be done only by a qualified electrician with a working knowledge of airfield lighting circuits. Trouble-shooting is accomplished by meeans of process of elimination. It should be chhecked that the POWER is OFF and secured, and o nce one solution is tried, POWER is reapplied. Then POWER turned OFF and secured and another solution tried, etc. Repeat this until the prooblem is solved.

It is also assumed that the circuit is in proper working order from the isolation transformer secondary connector (L-8233 style 7or 8 receptacle) all the way to and including the power source. Use of a calibrated true RMMS-reading multi-meter with a current sensing clamp-on attachment will aid in the trouble shootting of electrical circuits.
