Replying to: dave8697 (Mar 23, 2007 9:08 am) Thanks Dave, I'll try these things you've said and see how it works. The car just runs so good otherwise I hope it's an easy fix. How do I get to the throttle plate axle? Can that be done without taking anything apart? If not what needs to be done to get to it? Thanks again
#3298 of 4960 Rapid Parasitic Drain by piratedave Mar 24, 2007 (5:23 pm)
The battery in my 1995 Mitsubishi Montero drains very quickly - in just a few hours. The battery is new and alternator seems to be charging, OK. I have already tried pulling and replacing all fuses, relays and fusible links that I could find. I also tried disconnecting the alternator, starter and ignition switch but the volts would still drop rapidly when the + cable was re-attached. I have also tried chasing down shorts but haven't found anything obvious, yet. Any other ideas??

Replying to: piratedave (Mar 24, 2007 5:23 pm) with a voltmeter across the battery, or amp-meter in-line, as you pull and replace each fuse, have you recorded what voltage bumps, or current draw changes have occured for each circuit? because the one that causes the most significant bump is probably the circuit at fault. do you have multiple fuse / relay centers? for example, in my accord, there is one in the engine compartment, but then there are also two on each side of the lower dash. do you have any power windows, sunroof or seats? those would be my first suspect. another thing is possible here. that is your fuse / relay center is sitting in a moist environment and somehow shorting a hot circuit to ground.

Replying to: user777 (Mar 25, 2007 3:32 am) One word of caution while trying to find a draw on newer vehicles. Understand that some modules on newer vehicles are "stay alive" modules and will show a draw for quite some time after the vehicle has been shut off before they will shut down. Vehicles with things like cascade lighting, remotes, alarms and such will often have modules that are still "thinking" for upwards of an hour after the vehicle is shut down.

Replying to: 0patience (Mar 25, 2007 10:35 am) this is very true, but they most likely aren't significant current draws, certainly not ones that force a battery quickly down. maybe i'm missing your point.

Replying to: rocki7 (Mar 05, 2007 8:25 am) I've got a 97 S-10 with the same problem.

Replying to: user777 (Mar 25, 2007 3:32 am) Thanks. I tried pulling every fuse, again, just to make sure I didn't miss something and still didn't find the bad circuit. I have ordered a wiring diagram so I can make sure I'm not missing a relay somewhere - I already found some behind the dash. I also think it might be in the alternator cable - pulling the fusible link on that circuit stops the drain. Replies to this message: burdawg (Mar 26, 2007 8:05 pm) user777 (Mar 27, 2007 9:04 am)

Replying to: piratedave (Mar 26, 2007 5:08 pm) If you can disconnect the alternator and stop the drain, I would suspect the integral regulator in the alternator is shorted. Replies to this message: user777 (Mar 27, 2007 9:04 am)

Replying to: dave8697 (Mar 23, 2007 9:21 am) Problem solved. The idle has totally smoothed out since the bolt tightening on the vacuum fitting plate and the MAF sensor brushing with CRC. Checked mileage today on 296 mile tank and it was 28.5 for combined city and hwy. That is definitely back to normal and as good as 68,000 miles ago when I first got the car.
