Alternator Or Battery? On-Site Testing in Bedworth
Battery light on, or a car that dies after a jump in Bedworth? 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 Bedworth — priority response, single monthly invoice, no per-job admin, no chasing drivers for card payments.
Account customers get priority slots ahead of retail callouts, so a fleet job on your yard in Bedworth won't sit behind three domestic driveway jobs.
Charging faults found nearby
Recent job nearby: a vehicle in Bedworth 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 Coventry with an intermittent battery light. Ripple test showed a failed diode; the battery itself tested perfectly.
The readings that separate them
- Belt condition and tension are inspected, since a glazed belt slipping under load mimics a failing alternator.
- Ripple voltage is checked for failed diodes in the rectifier pack, which can charge adequately but destroy a battery over months.
- Bulk battery pricing — replacement AGM/EFB batteries at trade rates, not retail
- Every fleet jumpstart finishes with a charging-system reading, so the same fault does not reappear next week.
How the two faults present
Around Bedworth this comes up most with higher-mileage vehicles and with cars that have been repeatedly jumped by well-meaning neighbours.
Locally that means Bedworth itself plus the neighbourhoods that feed into it, with access via M6 J3 and A444 and a practical radius reaching Nuneaton (~4 mi) and Exhall (~1 mi).
Alternator vs battery questions
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 Bedworth and the CV12 area for this?
Yes. Bedworth is inside our routine coverage from Oldbury via M6 J3, roughly 5 miles from Coventry. We also cover the surrounding neighbourhoods on the same run.
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.How do we open a business account?
One phone call and a fleet list. First job on account can go the same day; formal terms confirmed by email overnight.
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.
