I like to recharge the (lead/acid) battery in my 98 p38 4.6 while it is still in use. So, I need to find out whether my rover is designed with positive or negative ground. I have searched but found no literature about this. Anyone knows?

...and anyone has tried to recharge an Optima or any dry-AGM battery? Thanks.

Negative Ground. Always negative ground.

I haven't heard this question in 30 years.

Just recharge your Optima as you would any wet cell battery.
