Alternator Or Battery? On-Site Testing in Ettingshall
Not sure if it is the battery or the alternator in Ettingshall? We test both under load before recommending anything. Mobile emergency jumpstart across WV2.
The two faults feel identical from the driver's seat and cost very different amounts to fix. The distinguishing test takes about ninety seconds with the engine running, which is why nobody should be guessing.
Stuck at the roadside in Ettingshall at 2am with a dead battery? We run a genuine 24/7 mobile jumpstart service — same price, day or night, no unsociable-hours surcharge.
Emergency calls are logged, timestamped and priced up-front. What you pay at 4am is what you'd pay at 4pm — no exploitation.
Charging faults found nearby
Recent job nearby: a vehicle in Ettingshall jumped four times in a week. Charging voltage 12.7V at 2,000rpm with lights on — alternator, not battery, and the owner stopped throwing money at parts.
Recent job nearby: a car near Bilston with an intermittent battery light. Ripple test showed a failed diode; the battery itself tested perfectly.
The readings that separate them
- Engine-off resting voltage establishes the battery's state of charge before anything else is judged.
- Belt condition and tension are inspected, since a glazed belt slipping under load mimics a failing alternator.
- Lone-driver phone support: we stay on the line until you're safe or we're on-site
- 24/7 Emergency Jumpstart work here is judged against the vehicle's own specification rather than a generic pass mark.

Alternator vs battery questions
Q.The car started on jump leads and then died. What does that mean?
Classic charging fault. The engine ran on borrowed energy and stopped when the battery could no longer supply the ignition system.
Q.Can a bad alternator ruin a new battery?
Yes, in both directions. Undercharging sulphates the plates; overcharging boils off electrolyte. Both shorten life dramatically.
Q.Do you replace alternators too?
We diagnose them on-site and can replace batteries on the spot. Alternator replacement is a workshop job, and we will tell you exactly what needs doing so you are not paying for diagnosis twice.
Q.Do you cover Ettingshall and the WV2 area for this?
Yes. Ettingshall is inside our routine coverage from Oldbury via A463 Black Country Route, roughly 1 miles from Bilston. We cover it alongside Bilston and the surrounding streets.
Q.I'm on my own and don't feel safe — can you stay on the phone?
Yes — we do this all the time. We'll stay on the line until we arrive, and you can share your live location if that helps.
Q.Will you come out in bad weather?
Yes — snow, ice, heavy rain, we still go. Batteries fail more often in bad weather, not less.
Who needs this test
