"Danger Danger Will Robinson"!

Probably not as dangerous as being 'Lost in Space' but with this lockdown we aren't using our cars so much. If it's been left for a week or so turn it over and let it run for a while.
Otherwise you come out to use it and 'Whirrrr, Whirrr, Dead'! Happened with my MX-5 today but thanks to my magic little 'StreetWize' box it started immediately and I let it run for 20 minutes to charge up.
That little box packs a huge punch for starting a dead car.
Make sure you put the streetwize box on charge though for next time!
