97 Grand Caravan SE short to ground? Battery drains!
Just found this fourm, looks great and seems like a good group of folks!
Here is my problem...a couple of weeks ago we tried to start our 97 Grand Caravan SE, when I twisted the switch all I got was a click! Tried again and click...once more and it actually fired! So we took it over to the AutoZone so they could check the charging system! Sure enough the alternator was bad (failed the diode check!). After many hours a few scrapes and a sore back my wife (yes she is a great mechanic and patient too!) and I got the alternator swapped.
Took it back to AutoZone everything passed but the battery was a little low. Got it home put the Battery Tender on it over night and all seemed well! 'bout 10 days later the oldest kid said the van wouldn't start right away so put the Tender back on it that night so she could drive it work the next day. That night took it back to AutoZone in hopes something simple was wrong...nope all was well! No charging problems, no error codes!
So two days ago I jumped into it and it cranked OK but then no indicator lights, no fan, no radio, no window control...the list goes on! After I got home, switched it off...waited a few sconds switched on, started right up and all the controls worked as expected! Turned it back off, bounced the ignition switch and got back a 12 55 and that was it! Battery is not low and I am completey at a loss!
Does a 97 Caravan have a BCM? Would a failing BCM cause the battery to drain? And act crazy? I was thinking it was a failing ignition switch but could it be that easy? Any ideas? Thanks in advance for the help!
