At Kinmel Campers, we see plenty of electrical issues with campervans, especially when it comes to split charger installations. Recently, a customer brought in their VW T6 after struggling with a battery system that simply wasn’t charging properly. This is a common issue many van owners face, and it can make life on the road frustrating. After all, without a reliable split charger, your leisure battery won’t power the essentials — from lights and fridges to inverters and USB ports.
In this blog, we’ll walk you through the problem, what we found, and how we carried out a full VW T6 split charger installation to get this van back to being road-trip ready.
What is a Split Charger?
A split charger is an essential piece of kit in most campervans and motorhomes. It connects your vehicle’s starter battery to the leisure battery and allows both to be charged while driving. The clever part? It ensures the starter battery is always prioritised, meaning you’ll never be left stranded with a flat starter battery.
There are different types of split chargers, from basic voltage-sensitive relays (VSRs) to more advanced DC-to-DC chargers designed for modern vehicles like the VW T6 with smart alternators.
The Problem: Faulty Split Charger in the VW T6
Our customer reported that their VW T6 leisure battery was not charging when the engine was running. This can happen for a variety of reasons, but in this case, we quickly discovered the culprit: a faulty split charger.
On closer inspection:
- The old relay wasn’t cutting in or out at the correct voltages.
- Several fuses had blown due to the wiring fault.
- Some of the wiring connections were not up to standard, raising safety concerns.
A faulty split charger can be more than just inconvenient — it can also be unsafe. Poor wiring or damaged fuses can lead to overheating and even electrical fires if left unchecked.
The Solution: New VW T6 Split Charger Installation
At Kinmel Campers, we don’t just replace parts; we install systems properly and ensure everything is wired safely for long-term use. For this job, here’s what we did:
- Removed the faulty split charger and assessed the wiring setup.
- Replaced all blown fuses with the correct rated fuses for protection.
- Installed a new split charger unit suitable for the VW T6 electrical system.
- Checked all wiring, re-routed where necessary, and ensured neat, professional connections.
- Fully tested the system to confirm the leisure battery now charges correctly while driving.
By the end of the job, the customer had a safe, reliable split charger installation and peace of mind that their battery system would work exactly as intended.
Why a Proper Split Charger Installation Matters
A lot of van owners underestimate how important a correct split charger installation is. Modern vehicles like the VW T6 often have smart alternators that require DC-DC chargers rather than basic VSR systems. Choosing the wrong kit can lead to flat batteries, damaged wiring, or inefficient charging.
A well-installed split charger ensures:
- Your leisure battery charges safely while driving.
- Your starter battery is protected from being drained.
- Your electrical system runs efficiently, avoiding unnecessary wear and tear.
- Safety is prioritised with the correct fuses and wiring.
