In case the bulbs do not light when the AC line switch is closed and the snap switch on the charger is in the "On" position, look for blown fuses in the AC line circuit. If the fuses are O.K. and there is AC power available at the panel, the trouble may be due to dirty contacts in the bulb sockets or they may be loose in their sockets. The socket contacts should be kept clean and the bulbs should be kept securely screwed into their sockets at all times. If this is not done the solder may melt out of the center socket-contact and cause trouble.

If the bulbs light but the ammeters do not show current with all switches in their proper positions for charging, check the fuses in the Tungar unit. These are accessible by opening the left-hand side door.

Use only 15 ampere fuses when making a replacement.

If the regulating switches are hard to turn, it is a good plan to lubricate the contacts and switch rider with a small amount of vaseline. This will also prevent the switch contacts from corroding.

The operation of the Tungar shown in Figure 45 is the same as the one just described. The panel of this Tungar has two extra snap-switches, which are not used in the operation of the charger.

The Rectigon charger shown in Figure 46 is similar to the Tungar just described except in the arrangement of the equipment. It also has two switches not used in the operation of the panel. One position of each of these switches is marked for "1 to 8 Batteries". They should always be kept in this position.

A spare Tungar bulb should always be kept on hand, and should be tested for at least one complete charge before being placed in reserve.
