Wait for instructions before cranking engine.
After a few seconds the test result will appear.
Compare draw reading with
manufactures specifications
If manufacturer’s specifications are not available the chart below can be
used as a general guideline. The amounts are in Amps.
NOTE:
For Truck, bus, and
other heavy-duty engines and
starters, refer to manufacturer’s
specifications.
If still out of specifications:
High
Amp reading may indicate engine is out
of time or a faulty starter. Some possible causes are shorted windings,
bent armature, broken housing or bad bearings. Repair or replace
starter as needed.
If the results are out of specification do the following:
<
Inspect the connectors for excessive voltage drop.
<
Repair or replace any defective cables or connectors.
<
Retest the system.
STARTER DRAW AND DIESEL ENGINES
There are a few points to consider in testing a starter on a diesel
engine. The BVA-350 is designed to recognize any significant amount
of draw; this includes glow plugs in small diesel engines. In heavy-duty
applications consider computer and accessory draw.
<
Make sure you start the engine quickly. The engine should be warm.
<
Turn the ignition on and allow the glow plugs to heat up and click off
before you run the Starter Draw Test.
<
Repeat the test in different ways and compare results.
