The boss in local battery centre says it's ok to connect neg charger
lead to neg terminal on battery.
However, car's user manual suggests connecting to somewhere on the
chassis. This can be a pain, getting a good connection. Any thoughts
TIA.
I don't see the reason for using the chassis unless testing the earth,
but you don't need a charger for that!
I persume the idea is to reduce current if anything shorts, thus
avoiding fire.
With a battery charger? Don't think even the very cheapest I've ever seen
was devoid of some form of protection against shorts.
That of course offers no protection against the leads wearing through and shorting.
NT
my old style battery charger has an overload thermal manual reset
switch, modern ones just shut down electronically (if the leads short
together)
I dread to think what the 600 amp Crypton jump start charger could do,
but the average DIYer does not have one.
