Testing for and Locating Tip Ground.

(a) Disconnect both leads from the feeder cable.

(b) Connect one lead of the test set to the ring side of the line toward the central office.

(c) Touch the other test set lead alternately and repeatedly to both of the open leads. A

relatively loud click will be heard each time the grounded lead is touched.

(d) Reconnect the leads as they were originally found.

(2) Repeat the procedure given in (1) (a) through (d) above at the following points:

(a) Where the leads connect with the distributing cable or line.

(b) Where the leads connect with the protector.

(c) Where the inside wire connects with the protector.

(d) Where the inside wire connects with the telephone set terminals.

(3) Continue fault locating by a process of elimination. Observe is the telephone is mounted

on a grounded surface. Note whether there is excessive dampness in the vicinity of the telephone or

whether some other unusual condition prevails. If either of these conditions has caused the fault,

remove the cause or remove the telephone to a suitable location. Determine the exact location of the

fault by opening up the leads that are connected electrically with the terminal L1 in the telephone set

and, with one test set lead connected to the ring conductor of the inside wire, touch each telephone set

lead as it is opened. A click will be heard in the faulty lead.

c. Testing for and Locating Tip Ground.

The term tip ground refers to an undesired electrical connection between the tip side of a

working line and ground. To test for and locate a tip ground, follow the same procedure as for a ring

ground (b) above.

d. Testing for and Locating Grounds on Tip and Ring.

(1) A tip and ring ground has the same characteristics as a short circuit, since the ring side of

the line is connected electrically to the tip side through the ground. Disconnect the faulty pair from the

feeder cable. Connect one test set lead to
