Battery Draining / Bigger amp Alternator
Posted 15 September 2003 - 11:12 AM
My alternator may be on the fritz as my battery is discharging overnight or after several hours being parked.
I reset the ground to the body thinking that may be the problem, and I unhooked the 8 guage power wire going to the back for amps and such. I am hoping it is something easy that causes the discharge.
Does anybody have any ideas on what to look at next?
Could the voltage regulator in the alt not be working right, or a short in the alt draining the battery? The hatch will run no problem after I jump it and it will start a few times after it is fully charged.
If I need a new alt, I remember talk of using one from an xt6 or something. It supposedly is like 125 amp vs. our 85 in the ea-81. Someone care to verify those values? Also, someone care to comment on wether it is just a straight drop in, or does it need some modification (new belt etc)?
Any help would be appreciated.

Put an ammeter in series with your battery with ignition off; current draw should be close to zero (in the low milli-amp area). If it is 1/2 amp or more, start disconnecting fuses one at time and see where the current draw drops to near zero--that'll be the area where you need to look to solve the discharging problem. If you find that there is no apparent current draw with the ignition off, you may have a battery that just will not hold a charge; unusual, but it happens.

i would check out or replace the battery to start with.
if the alt is reading 14 volts then its good.
take your ride to autozone, they have charging system diagnostics for free. if anything is bad, they will tell you, in hopes that they can sell you a replacement!

Hi. I was just nosing around looking for replies to my post and I found your message. Doesn't apply to my 95 Legacy but I LOVE the Eisenhoweer quote -- is it real??
someone found a 110 amp alternator from a datsun or chevy luv or something, didn't they?
