dual battery dramas
Posted: Tue Mar 24, 2009 7:12 am
Got a dual battery set up in the GQ, nothing fancy, bit of cable between them with a manual switch. Everything is powered off the main battery, if I turn the switch off it osolates the second battery. I usually leave it on, just turn it off of I'm parked with the radio on.
Is this a bad set up or something? Had the car 18 months, the second battery died soon after I got it. Left it disconnected, replaced it after a while. Main battery died about 2 months ago. Drove the car on Saturday, started fine. Went to start it Sunday night and it's dead. Alternator is working fine. If i jump it, drive around for a while then turn it off it'll start right away, just doesn't want to hold charge over night.
