Simple Battery Mod

Did a simple battery mod the other day. I use the gran finale all year round but there are times when she won't get a run for a few weeks. Early cars use a metal support frame to hold the battery in place, later cars use this plastic cover. Anyway, I was getting a bit fed up of taking the cover off and un-bolting the earth strap or forgetting to disconnect the earth and having a weak battery. I bought this battery switch off ebay for about 6 quid, and as shown cut out a section of plastic. Now it's quick and simple stop battery drain.
