6.2 – Normal Function Test Procedure
This section deals with “normal function” test proce dures. It includes
all steps necessary to ensure that the TI45014D Battery Charger/Con-
ditioner is operating within spe cified para meters prior to use. A digital
multimeter (an example is shown in Figure 6.2.1) capable of measuring
dc voltage and resis tance will be required to perform some of the tests.
These functional test procedures should become routine.
Check Unit for Evidence of Damage
Check for dents, punctures, case distortion or misalignment, and cracked or loose connec tors. If any
damage is evident, contact the Tesla™ Customer Service.

Severe injury or death from electrical shock can occur.
Ensure that both the ac input cable and dc output cable
are disconnected before performing any tests.
WARNING
Checking Unit Internal Resistance (Testing for Shorts)
It is essential to test for shorts to detect any problems with the unit. To do so, you will need to set your mul-
timeter to measure Ω or “resistance.” You can test to see if both the ac input and dc output terminals are
isolated from the case and line ground in the following steps.
Step 1
Place the negative probe (black) of the multimeter on the ac plug ground pin and the positive
probe (red) on one of the screws of the ac input (figure 6.2.2)
> The multimeter should read nearly 0 Ω.
Step 2
Move the positive probe to one of the two ac plug blades.
> The multimeter should now read greater than 1 MΩ.
Step 3
Move the positive probe to the other ac plug blade.
> The multimeter should again read greater than 1 MΩ.
Step 4
Next, move the positive probe to the dc output cable black alligator clamp.
> The multimeter should read greater than 1 MΩ.
Step 5
Finally, move the positive probe to the dc output cable red alligator clamp.
> The multi meter should read greater than 1 MΩ.
If the following multimeter measurements correspond to the above steps, the unit has no internal shorts.
