Thanks for everyone's input especially Jay, bit of a confession to make - in the end I winged it as the new multi meter instructions were super complicated, lol still in it's box..but the good news is nothing has happened, battery remains charged despite lots of small journeys.

If it's okay, i might dig it out and stick a pic up here for basics.
