Perry Casson said, "....my first battery was a bit low and even though the
engine would turn over and the plugs would fire the injectors were not
getting triggered."

What happens to your engine, i.e., the injectors that "were not getting
fired", if and/or when you have an alternator failure and the battery starts
to droop?

Sounds a bit like a problem just waiting to become a disaster, to me.
