Is It The Battery Or The Charging System? Wollaston van jumpstart
Not sure if it is the battery or the alternator in Wollaston? We test both under load before recommending anything. Mobile van jumpstart across DY8.
A simple rule of thumb: a battery fault stops you starting, a charging fault stops you continuing. If the car jumps easily then dies a few miles later, the alternator is the prime suspect.
Van won't turn over in Wollaston? Nine times out of ten it isn't the starter — it's a tired leisure or main battery that can't hold cranking amps on a cold morning. We come out with a heavy-duty booster rated for diesel commercials.
Around Wollaston the common jobs are morning no-starts on the yard, lunch-break dead batteries at customer sites, and end-of-day flatlines after tail-lift or refrigeration use.

How the two faults present
Around Wollaston this comes up most with higher-mileage vehicles and with cars that have been repeatedly jumped by well-meaning neighbours.
Locally that means the streets between Wollaston and Stourbridge, with access via A491 and A458 and a practical radius reaching Stourbridge (~1 mi) and Wollaston (~1 mi).
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.
- Alternator output tested at idle and at 2000 rpm before we leave, so we know the recharge will actually work
- On a van jumpstart the equipment is matched to the vehicle — cranking current, terminal layout and battery location all change the approach.

Charging faults found nearby
Recent job nearby: a vehicle in Wollaston 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 Stourbridge with an intermittent battery light. Ripple test showed a failed diode; the battery itself tested perfectly.

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 Wollaston and the DY8 area for this?
Yes. Wollaston is inside our routine coverage from Oldbury via A491, roughly 1 miles from Stourbridge. We cover it alongside Stourbridge and the surrounding streets.
Q.My van cranks slowly then dies — is that the battery?
Usually yes, but sometimes it's the starter drawing too much current or a bad earth. We test all three on the driveway before recommending a replacement.
Q.Do I need to register a new van battery to the ECU?
On Sprinters, Crafters, T6 Transporters and newer Custom Transits — yes. We carry the OBD tool and code it as part of the fit.
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.
