"My Tahoe was eating a battery every week. Two shops said 'replace the battery.' Ground Works found a stuck trailer brake controller pulling 1.2A overnight. Fixed in two hours."
Drains, shorts, dead circuits.
Mobile electrical diagnosis and repair across Hampton Roads. Parasitic drains, flickering lights, dead modules traced and fixed.
Electrical work is where most shops give up or guess. We bring a scope, a multimeter, a labeled fuse-pulling routine, and the patience to chase a signal from the battery to the ground point and back. Parts thrown at problems is how shops cost you $1,500 finding what we find in 90 minutes.
Parasitic drain. Something is staying awake when the car should be asleep. We hunt the circuit pulling the current.
Headlights dim with RPM, interior lights pulse, gauges dance. Usually an alternator, ground, or voltage regulator issue.
ABS, traction, airbag, CEL all on at once. That's not three problems, that's one bad ground or low voltage everything is sharing.
Tach jumps, fuel needle drops to empty and back, temp gauge cycles. Instrument cluster or its power supply is failing.
HVAC blower runs on 4 only, or specific speeds dead. Burnt resistor pack, almost always. 30-minute fix.
Installed years ago, now causing random horn chirps, locks cycling, intermittent no-starts. Bad install catching up.
Listen to the symptom, scan for codes (modern cars have codes for circuits, not just engines), check the wiring diagram for what's on the suspect circuit.
Multimeter at the sensor, at the fuse, at the ground point, at the ECM connector. Voltage drop tests reveal corrosion or breaks the scope alone won't catch.
Trace the wire physically: wiggle test under live load, check connectors for green crust, pull harness tape where rodent damage is suspected.
Solder + heat shrink for splice repairs. OEM connectors when one is bad. Clean and re-torque grounds. We fix what's broken. We don't throw a sensor at it and hope.

"Three dash lights, no shop could connect the dots. They found a corroded chassis ground behind the headlight, cleaned it, retorqued it, all three lights went out."
"Aftermarket alarm from 2009 was causing random no-starts. They ripped out the bad install, fixed the spliced wires properly, and the car has started every single time since."
It's time, not parts. A parasitic drain hunt can take 2-3 hours just to isolate the bad circuit. Then another hour to find the actual component on it.
We bill flat-rate by the hour for diagnosis, then quote the repair separately. Most jobs cost less than people fear. We'd rather find it fast than drag it out.
Yes. Solder joints, heat shrink, OEM-spec connectors. We repair the harness. We don't use Scotchloks, wire nuts, or electrical tape as a final repair.
If a harness section is too damaged to splice (rodent damage, heat-melted insulation), we can replace just that section with OEM or quality replacement harness.
Ammeter inline at the negative battery terminal, then pull fuses one at a time until the current draw drops to spec (under 50mA on most cars). The fuse that drops the draw is on the bad circuit.
Then we look at the wiring diagram for what's on that circuit and trace it to the actual stuck component. Tedious but reliable, and it doesn't involve replacing the battery or alternator on a hunch.
Very common. Bad installs leave half-stripped wires bundled with electrical tape, parasitic loads on circuits that shouldn't have any, and grounds tapped into the wrong places.
Parasitic drains, intermittent starts, random horn chirps, door locks cycling on their own: a huge percentage of these trace back to an aftermarket install from 5-15 years ago.
Usually yes. Most diagnosis happens at the fuse box, ground points, and connectors in the engine bay. Pulling dash trim is a last resort, and we tell you before we get there.
If the dash has to come apart (cluster fault, behind-dash harness damage), we explain the time required and quote before disassembly.
Fill this out and we'll call you back, usually within the hour during business hours. No bots, no call center, no obligation.
Electrical diagnosis at your driveway. Parasitic drains, flickering lights, weird codes. We find them, not guess at them.
