Hi John,
I've also got an '02 190P on the Chev chassis (I think there are probably at least 1 or 2 others
on here as well) and not to frighten you, but I've had my share of head scratchers over the last 2
years since we purchased it, so if you have any questions, fire away. If I've had the same issue,
I'll be glad to help. There are many good sources of info on here, digital and human, as well as a
great keyword search facility up in the top right corner of most pages.
btw, markopolo and Ron are correct about the battery locations and methods of access. You won't
be able to get at either house battery from inside your van, if yours is a Chevy Express 3500 base.
When you're ready to winterize (or just need a quick reference guide for something) here's a decent
website to check. (If you can't find the answer on here
)
