Marine electrical issues we’re called for most often

Battery drain / batteries dying unexpectedly

Charging issues (not charging, under/over charging symptoms)

Charging issues (not charging, under/over charging symptoms)

 Our technicians inspect the battery system, charging components, and connected electronics to identify common causes such as parasitic draws, faulty connections, aging batteries, or install-related wiring issues. By narrowing down the source of the drain, we help restore reliable power and prevent repeat failures. 

Charging issues (not charging, under/over charging symptoms)

Charging issues (not charging, under/over charging symptoms)

Charging issues (not charging, under/over charging symptoms)

 Our technicians inspect the charging system components, including the alternator or stator, voltage regulator, wiring, and connections, to identify the source of the problem. We look for issues such as faulty regulators, poor connections, damaged wiring, or incorrect system setup that can cause improper charging behavior. 

Intermittent power loss to accessories or helm

Charging issues (not charging, under/over charging symptoms)

Intermittent power loss to accessories or helm

 Our technicians inspect common failure points such as battery connections, main power feeds, fuse blocks, breakers, switches, grounding points, and helm wiring. We look for loose terminals, corrosion, heat damage, or intermittent faults that disrupt consistent power delivery. 

Blown fuses / tripping breakers

Pumps not running (bilge/ live well/ washdown) due to electrical faults

Intermittent power loss to accessories or helm

 Our technicians inspect affected circuits, wiring, fuse panels, breakers, and connected accessories to determine the cause of the fault. We look for issues such as improper wiring, excessive current draw, damaged insulation, or failing components that trigger protective devices. 

Corrosion-related connection issues

Pumps not running (bilge/ live well/ washdown) due to electrical faults

Pumps not running (bilge/ live well/ washdown) due to electrical faults

 Our technicians inspect exposed and high-risk electrical connection points including battery terminals, grounding points, fuse blocks, switches, and wiring connections. We identify corrosion buildup, compromised terminals, damaged wiring, and moisture intrusion that can disrupt electrical continuity and system performance. 

Pumps not running (bilge/ live well/ washdown) due to electrical faults

Pumps not running (bilge/ live well/ washdown) due to electrical faults

Pumps not running (bilge/ live well/ washdown) due to electrical faults

 Our technicians inspect the electrical side of the pump system, including power supply, switches, fuses, breakers, wiring, grounds, and connections. We determine whether the issue is caused by wiring faults, corroded connections, failed switches, blown fuses, or other electrical problems rather than a failed pump itself. 

“Ghost” issues (works sometimes, fails under load)

“Ghost” issues (works sometimes, fails under load)

“Ghost” issues (works sometimes, fails under load)

 Our technicians inspect common and less-obvious failure points, testing power delivery, connections, and system behavior under operating conditions. By evaluating how systems perform when demand increases, we can identify weaknesses that cause electronics or accessories to fail unpredictably.
