Alternator Or Battery? On-Site Testing in Quarry Bank
Battery light on, or a car that dies after a jump in Quarry Bank? That points to charging, not storage. On-site diagnosis and Fleet & Business Jumpstart.
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.
Business account jumpstart and battery replacement across Quarry Bank — priority response, single monthly invoice, no per-job admin, no chasing drivers for card payments.
Fleet vans die from parasitic drain more than anything — trackers, dashcams, tail-lifts, refrigeration. We identify the drain, not just recharge the battery.
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.
- On-site fleet audits available — we check the whole yard once a quarter and flag ageing batteries before they fail
- Every fleet jumpstart finishes with a charging-system reading, so the same fault does not reappear next week.
Charging faults found nearby
Recent job nearby: a vehicle in Quarry Bank 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 Cradley Heath with an intermittent battery light. Ripple test showed a failed diode; the battery itself tested perfectly.

Alternator vs battery questions
Q.Do you cover Quarry Bank and the DY5 area for this?
Yes. Quarry Bank is inside our routine coverage from Oldbury via A459, roughly 1 miles from Cradley Heath. We cover it alongside Cradley Heath and the surrounding streets.
Q.Do you do preventative fleet audits?
Yes — quarterly on-site checks: voltage, load test, alternator output, terminal condition on every vehicle. Reports emailed to your fleet manager.
Q.Can you supply and fit batteries at trade price?
Yes — Yuasa, Varta, Bosch and Exide at proper trade rates for account customers, fitted on your yard with OBD coding included.
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.

The short version
Storage fault or supply fault — the tests are different, the costs are different, and guessing is expensive. Every visit here includes the charging check. Either way you get the readings, the reasoning and a working vehicle before we leave.
