Work away, so RS not touched for 5 weeks at a time...
Disconnect the negative from the battery every time I leave and during the summer had no probe starting when I returned...
Notice around October that had to jump start once or twice but then ran / started no problem

Yesterday had to jump start....went for a 10-15 mile drive ( nice weather ) ... back into the garage, switch off... try restarting.."click", nothing !!!!

Onto trickle charger.... 2mins later showing full charge.. ????

Radio, lights, auxiliaries seem ok...

Thanks for any input..
