Default starting problem

my 86 has a duralast battery in it which is only 6 months old but if the car sits for more than like a week i have to jump it. why do you think this is. after i jump it then let it recharge it is fine as long as i drive it frequently.

there is some kind of draw. you need to find out what isn't shutting off (alarm light ?? hood light ??) you can just add a simple battery cut off switch, that'd cure it til you got tired of having to pop the hood every time. or you could somehow add a tricle charger through the cig lighter. any battery hooked to a cig lighter adapter would power all the 12 volt stuff... it would die b4 the battery died and would be much more PITA then a switch... but maybe you have an iverter in your garage or something... just a suggestion but a long shot

this happened to my freind, it ended up being a current draw form a badd circuit in the fuse box, you need to get yourself a multimeter and go to town lookin for that power draw

hook a dvom in series with neg battery terminal to post and set dvom to amps and measure current draw, 25-50 milliamps is safe at rest draw, if more pull fuses until draw is removed identifying circuit draw is on, back trace from there LUK

check for melted wires, i had the same problem with my car. its not a DD so it some times sits for months. turned out one of my down pipes melted a wire bare and the wire was constantly touching the pipe, causing electricity to drain

thanks. i had a feeling it might have to do with the plug underneath the driver's seat. i had an extra one so i decided to put that one on and see if that solved it. unfortunately i didn't realize i wouldn't be able to figure out where the wires go lol. does anyone know? there are 4 wires and 4 prongs on the plug, i just don't know which go where.

if its an empty plug, there can be no current draw on it, as its not plugged into anything.
