2007 Quest Battery Draining
This is an intermittent problem; occasionally the battery will drain to the point of no starting when the van is turned off and key removed. Jump starting fixes everything. Battery and alternator check good, have not attempted to pull any codes (yet). Today, I started the van, ran it for a few minutes then turned it off. Packed the van opened and shut the doors a few times, all normal. Couple hours later would not start, just clicking relays. I actually noticed the clicking before I got into the van (KEY OUT). Opened the hood and the IPDM cover, initially thought it was the ECM relay clicking, pulled the relay, clicking stopped there but other relays clicking, including one under the dash by the fuses. Again, this is all with the key out and the vehicle off. Jump started, all normal, ran fine all day, cannot duplicate. Is there any way to troubleshoot the individual relays? I thought this may also be ignition switch related since key was out, but again tough to diagnose when it gets jumpedf and is normal for days. next will be to hook an ammeter to figure out if there is a huge drain with the vehicle off, but again, seems to work for a long while just fine, then something drains the heck out of the battery.
