Folks,
Having suffered through early A1 "ground-gone-away" problems,
every A1 & A2 I've had since then have had a supplemental strap
installed. I found it easiest to use some #8 (or maybe it was #6)
stranded wire and run from the alternator bracket mounting, across
the back of the slam panel, and down to the negative post on the
battery. Just make sure that you flux & solder all the connectors
then use some shrink tubing to ensure nothing gets in to start
corrosion........Jack
Any particular place on the head best?
