h the old
electrolyte, which has been saved, provided no impurity has entered
the electrolyte. After filling, allow the battery to stand for 12
hours and then charge, using 6 amperes for KXG-7 size and 12 amperes
for the KXG-13 size. Charge at this rate until all cells start gassing
freely or temperature rises to 110 deg. F. Then reduce the charging rate
one-half, and continue at this rate until the specific gravity is at a
maximum, five consecutive hourly readings showing no rise in gravity.
At least 40 hours will be required for this charge. To obtain these
low rates with the Delco-Light plant, lights or other
current-consuming devices must be turned on while charging.

General Complaints from Users and How to Handle Them.

1. Pilot balls do not come up.

This condition may be caused by

(a) Battery discharged.
(b) Weak electrolyte caused by spillage in shipment.
(c) Defective ball.

Question the user to determine whether the ball will not come up if
the pilot cell is bubbling freely. Weak electrolyte or a defective
ball will require a service trip to determine the one which is
responsible for the ball not rising. (See page 470.)

2. Lights dim-must charge daily.

This condition may be caused by

(a) Discharged battery.
(b) Loose dirty connections in battery or line.
(c) Low cells in battery.

The user should be questioned to determine whether the battery is
being charged sufficiently. In case the user is positive the battery
is charged, the next probable trouble would be that there were some
loose or dirty connections in either plant or battery. Have the user
check for loose connections. Should it be necessary to make an
inspection trip, instruct the user to give battery an equalizing
charge so the battery will be fully charged when the inspection is
made.

Low cells can be checked by asking the user if all of the cells bubble
freely when equalizing charge is given. In case user claims several
cells fail to bubble, an inspection trip would be necessary to
determine the trouble. (See page 470.)

3. Cells bubbling when on discharge.

This complaint would indicate a reversed cell. (See page 483.)

4. Cells overflowing on charge.

This would mean that the cells were filled too high above water lines.

5. Engine cranks slowly but does not fire.

This would indicate over-discharged battery. Explain to user how to
start plant under this condition.

6. Plant will not crank.

This might be cause
