Car Keeps Needing Jumpstart

[R33GOD]

just recently my car isnt starting without the need of a jumpstart. (r33gtst) i went to bob jane and checked it out. battery is perfect, alternator is perfect.

came up as an error though as power drain or something like that.

this has got me puzzled.

what could it be?

Have you checked the battery terminals?

Loose earth cable?

Happened to me couple of days ago, resulting in new terminals.

These two things that springs to mind with situation like this.

Hope it helps

Cheers

i had this problem in my old vk... (P.O.S. btw)

turned out it was dirty battery terminals... the battery was leeking some shit out (whitish in colour) that was coating them and preventing it connecting...

wash in hot water see if fixes

also check all your belts for slipping

have you installed anything recently?

check to make sure everything is hooked up to accessories and not constant power.

starter motor might be rooted.

[sh@un]

you've got a short to earth somewhere

[paulr33]

go see an auto elec

Had same problem ,was starter motor had it rebuilt problem gone

Get a multimeter, set it to the 10AMP setting. Take a battery terminal off, set it to current, put the multimeter inline and check for any power draw with everything turned off. It should have a small amount or nothing at all.

Yep, what you want to do is like GTR-ben said, grab a multi meter and use the amps setting and do some testing.

Another good place to test is your fuse box, when the car is off, pull a fuse on a circuit and use the multi meter probes to bridge the gap and if the car is off you should get next to nothing. (Make sure the probes are in the AMPS terminals of the meter, because they are usually different to the volts terminals)

Common things that do cause current draw when the car is off are internal lights, alarms and shorts to earth.

So that should at least allow you to find which circuit is draining ur battery overnight.

Hope that helps dude.

couldnt find the problem. took the power cable off the stereo also.

last couple of days now if i switch the car off and try to start it just after 2 hours later it wont start. auto elec time

How old is the battery? Just because it checks out as ok doesn't mean it's accepting and holding charge. Check the battery voltage before you even crank the engine. Then check it while you crank the engine.

Is the alternator working properly, and the regulator. If the regulator (built into the alternator) is cactus, then it might be overcharging the battery. And batteries don't like being overcharged.

[W0rp3D]

Hmmm, that is odd, batteries dont normaly last 12 yrs, i have an odyssey that is only a few yrs old and had to replace that on the weekend, you should here it spin up now with a 1000cca dry cell.
