) then, adjust dis­
trib u to r c o n ta c t poin t gap to .019” (new p oints) or
.016” (used po in ts). Breaker arm rubbing block
m ust be on high point o f lobe during adjustm ent.
N O T E : If contact points have been in service, they
should be cleaned w ith a point file before adjusting
w ith a feeler gauge.
• Check d istrib u to r poin t spring tension (co n ta ct
poin t pressure) w ith a spring gauge h o o k ed to
breaker lever a t the c o n tac t and pull e x e rted at 90
degrees to the b reaker lever. The p o ints should be
closed (cam follow er betw een lobes) and the
reading tak en ju st as th e points separate. If n o t
w ithin lim its, replace.
Excessive poin t pressure will cause excessive
wear on the p o in ts, cam and rubbing block. Weak
point pressure perm its bouncing o r clattering, re­
sulting in arcing and burning o f the points and an
ignition miss at high speed.

1. M easure th e specific gravity o f the electrolyte in each cell
(Fig. 7). I f it is below 1.230 (co rrected to 80° F.)
recharge w ith a slow rate charger, or if desired, further
check b attery .

2. C onnect a voltm eter across the b a tte ry term inals and
m easure the term inal voltage o f the b a tte ry during
cranking (disconnect the coil prim ary lead at the negative
term inal during this check to prevent engine from firing).
I f the term inal voltage is less than 9.0 volts at room
te m p eratu re, approxim ately 80° ± 20° F., th e battery
should be fu rth e r checked. See S ection
6
Y for further
tests.
3. Inspect for signs o f corrosion on b a tte ry , cables and
surrounding area, loose or b roken carriers, cracked or
bulged cases, dirt and acid, electrolyte leakage and low
electrolyte level. Fill cells to proper level w ith colorless,
odorless, drinking water.
The to p o f the b a tte ry should be clean and the
b attery hold-dow n b olts properly tightened. Particular
care should be taken to see th a t the to p o f th e b a tte ry is
kept clean o f acid film and dirt. When cleaning batteries,
wash first w ith a dilute am m onia or soda solution to
