The boss in local battery centre says it's ok to connect neg charger

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.

Doesnt explain why all car user manuals dont say that.
