Parasitic Drain Diagnosis
If your battery keeps going flat overnight or after a few days, there is usually an unwanted electrical load staying awake when the car should be asleep. Replacing batteries again and again rarely fixes the root cause.
Q. My battery is new but still goes flat, what now?
A. We test the charging system, then measure sleep current and identify the circuit/module causing the drain.
Q. Can you find drains faster than most garages?
A. Yes. We combine current draw testing with thermal imaging to visually pinpoint heat from an active circuit/module.
Q. Is this a quick job?
A. Sometimes, but many drains are intermittent. We work methodically and advise upfront if extended time is required.
Q. What causes parasitic drains?
A. Common causes include modules not sleeping, faulty switches, aftermarket accessories, water ingress, and wiring shorts.
Q. Do you provide a report for garages/fleets?
A. Yes. We can provide findings (circuit, module, evidence) to support repair decisions.
Note: Parasitic drain work is a specialist diagnostic service and is priced accordingly. If you’re calling from a garage, we can support diagnosis and hand back clear next steps.
