Best Practices, Tips, & Techniques

Poor electrical connections cause most of the electrical charging system problems. As a result, A&Ps, FBOs, mechanics and owners chase this problem creating unnecessary expenditure & frustration.

  • Poor electrical connection problems include but are not limited to flickering panel meters, lights, and fluctuating bus voltages.
  • Always check for and replace open, frayed, or broken wires
  • Clean thoroughly or replace corroded, dirty, or oxidized connections terminals, contact, or poorly soldered wire junction.
  • Check for voltage-drops across the Field, Alternator Switch, Alternator Circuit Breaker, and Alternator Controller Unit (ACU). High voltage-drops mean excessive junction resistance.
  • kamagra uk, kamagra 100 kamagra uk
  • Check for an open stator wire or open diode in the Alternator when the Alternator only carries about half its rated output.
  • A Ground shorted Alternator field will damage most Voltage Regulators.
  • Do not connector an ACU, Voltage Regulator to a ground shorted Alternator.
