can a starter drain a battery?

[bigwaylon]

I've had an electrical problem since somebody rolled my TJ in July...

haven't spent much time tracking it down...but it's a slow drain somewhere...

I can crank it and drive it no problem...as long as I crank it every 3-5 days...

let it sit for a week or more, and I have to jump it off...

not sure what could've busted loose on a flop...only thing I know of that's broken is the XM antenna wire...and with the power off, I don't "think" it's still using power trying to locate the satellites, but I'm not sure...

went out today to do one of my routine cranks, and it just turned over and over and over...

didn't hear the fuel pump running, so I just swapped the fuses/relays for anything fuel related with non-fuel related (rear O2 sensor, horn, etc)...OK, I know that the rear O2 is actually fuel related, but I don't even have on anymore, and it wouldn't prevent a start...

just trying to rule things out...would a starter going bad be able to drain a battery over a couple days?

any other random ideas?

best thing to do, charge the battery fully, take a DVOM and set to DC amps, disconnect negitive cable and put leads of DVOM inline between cable and battery.

read the amp draw, should be less than half an amp ( leave it connected for a few minutes if the draw is higher, as the computer systems may take a bit to go into "sleep" mode)

if the reading is above an amp, pull fuses till the draw goes away

start with radio, then lights, ABS, SRS, might have to reinstall to doble check.

Dome light switch isn't on is it ?

dome light isn't on...

but, it does have a switch wired into it (one of those Quadretc switches my wife bought me for Christmas)...and that was pulled out of the fuse box when I looked today...but I don't "think" the light was on...

I think I understand your "pull fuses" process...so I'll work on that in the next couple weeks...

***not sure on a jeep***
On a GM Starter/solenoid is integrated. And a faulty solenoid and relay can drain battery.

Ive never really contemplated the why's just know that I have seen the battery drain/change starter/ problem fixed scenario
