Electrical troubleshoot

Am tackling getting 03' started after hiatus. Series of previous fixes, relays fuses, looking parasitical drain. Went into limp mode once, replaced alternator twice, new battery (12.7 +) . I just went out and hooked up fresh charged battery and cooling fan came on just like before. I didn't even bother starting, cause this is something wrong. If there is a link or trouble shoot guide here to get me started would be of great service. I'm only w mobile for another week, so couldn't really get search happening for this. What would make radiator fan come on without key in ignition, and what is the most common parasitical issue, and any good basic starting troubleshooting link. Thanks a lot.

Not sure why the shun here, but there is very helpful Volvo tech facebook page
Replacing the fan module might also be parasitical drain. Known bad issue for P2. Thanks everyone who chirped in.

Kraig,

You posted on the P3 forum not the P2 forum

Start a new post on the P2 forum.

Good Luck
