Diagnostic Tips:
Tools you need to effectively diagnose electrical performance issues:
•
•
•
•
Knowledge & understanding
An electrical performance problem
DVOM
Ammeter (current sensing device
What to check:
•
•
•
Is current flow higher or lower than expected?
Check the supply
Activate the circuit and do voltage drop tests
o
o
If the above tests check out, then suspect the load device itself.
Check the feed side
Check the ground side
•
These test procedures are non-invasive. You do not need to open a circuit for testing.
You can isolate out the high resistance problems with confidence!
