Damn this never ends...

checked my E-fan and its all ok, when i turn on my car with a full battery then i put my battery and i hear my alternator belt Squeal under stress for 5 secs, then puff back to normal, meassured 14.X volts on the battery when car running, i turn off turn on ok all good

but overnight, dead battery, i know parasitic draw, bad battery, ok, but now How can i hunt down my parasitic draw? or dead battery (No they dont test them they just sell me another one...)

So how can i track down my issue? Hope to hear something... Thx!

Get you a multimeter. Set it to mA. Test your battery while the car is not running, and make sure to let it sit for about 10 mins after shutting it off. should be around 20-30mA when off. If you're getting a reading higher than that, leave your multimeter on the battery, and go to the fuse box. Start pulling fuses until the draw drops down to the ideal amperage. 9 times out of 10 its going to be a Radio related issue, so check that first. Begin to pull the fuses until you isolate the problem circuit, then fix accordingly.

Time to find a new supplier for your battery and other car parts. Any good place will test first. Even the places that charge 4 times regular price will test the battery first. They just lie and say the battery is gone when it only is in need of charging.

If they won't test your old battery don't buy a new one at that store.

"1989 240sx KA24E @ Dominican Republic "

That part specially "@ Dominican Republic" if i go to a store to "test it" ill just be another customer they`ll throw lame reasons and halfassed tests to make profit out of me, prolly in the end ill just end up buying a new one from them or just going home with a lie "The battery is good", why? their test is prolly just charging it a lil and testing a light bulb to see if it turns on XD Profit comes first!
