Test 1 - Starting And Cranking Voltage; Test 2 - Starter Current Draw - Craftsman 161.210400 Owner's Manual

Test Number 1--Startin_ and Crank ing_Vg.!tage,
I. Place function switch in the VOLTS position. Engine must be disabled
to prevent Starting for this test. On ELECTRONIC IGNITION, disconnect
battery cable at coil or unplug pickup coil connector at distributor
or ground HT secondary lead on any external coil system. ,
2. Close starter amp shunt (See page 6, Figure 6) before operating starter.
3. Have an assistant turn the ignition switch to the START position and
operate starter for 15 seconds. Observe battery voltage reading
with engine cranking, (Figure 8).
4. A battery in good, fully charged condition should read a steady 9 volts
or more.
5. If the battery voltage reads below g volts, recharge battery to full
charge condition.
6. Excessive fluctuating voltage reading (over i volt) can be caused
by a starter in poor condition due to worn bearings, dirty commutator,
a defective battery or corroded starter cables, Clean, tight connec-
tions are a must throughout the starter system.

I. Place center slide switch to the right hand starter amps position.
Operate starter and note starter current on the 400 Amp scale, (Figure 10),
Compare to specifications. IMPORTANT--Always return switch to center
position for other tests when amps reading is compieted{AZ_o _¢e F_gu_e 15J.
2. If battery-starter test is normal (a steady reading over 9 volts),
proceed to Test Number 4_Cha_gingS_stemVg]tage and Current.
