[s-cars] Current draw/dead battery "a short story"

[Mark Strangways]

Glad it seems to be coming to a close.. (your battery drain, and not the 
thread).
I may be getting in touch with you for some "known good" parts, should you 
wish to part with any.

My afterrun pump drama is yet to come I am sure. Luckily we have discussed 
this and I have a much better place to start looking.

Mark
