STARTING TEST cont.
There are a few points to consider in testing a starting system on a diesel
engine. The BVA-460 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 Starting Test.
If the results are out of specification do the following:
If manufacturer's specifications are not available the chart below can be
used as a general guideline. The amounts are in Amps.
• Inspect the connectors for excessive voltage drop.
• Repair or replace any defective cables or connectors.
• Retest the system.
If still out of specifications:
High
Amp reading may indicate
engine's ignition system is out of time or a faulty starter. Some
possible causes are shorted windings, bent armature, broken
housing or bad bearings.
