Review: Worth every penny - Excellent product,made me look very clever.
Review: Brilliant piece of kit - Fitted it to my van. Has been working great. Instructions are very clear. finding a hole or making a hole to run the cable to the car battery was a bit tricky but it depends on the model. Some models have easily Accessible pre drilled holes. My kangoo was a bit of a nightmare. I had to remove my car battery and air filter to gain enough access to drill a hole. Once this was done it was very easy. Ran cable into cab under the passenger door seal and into the back where my deep cycle battery is located. so much easier than taking it out every couple of weeks to recharge. once fitted just drive around and the battery is charged. Very happy.

## Questions & Answers

**Q: Can this be fitted in a Fiat ducato 1988**
A: Can’t see why it couldn’t I fitted to a 2006 caddy had to get extra wire as it wasn’t quite long enough so make sure before you order you map your run and check if you need this one or the 5m one

**Q: Why is my relay clicking on and off when im driving now**
A: If you have a smart charging alternator it will not charge all the time so relay would cut in and out

**Q: Is this kit compatible for none smart alternator vehicles also..**
A: It should be as I fitted this on our 1998 campervan

**Q: I have this item but it doesn't seem to switch off and isolate batteries after the ignition is switched off. what could the issue be here?**
A: We've fitted ours today.  The instructions say that sometimes if takes a few minutes to work when the ignition is switched off.  Have you tried giving It a couple of minutes?
