You will need a volt meter for this!
first remove the neg. clamp of your battery..
connect the pos.[red]of your volt meter to
the neg.camble and the [black] neg wire of the
volt meter to the neg. post of the battery.
if there is a draw it will show on your meter.
if thats the case start pulling your fuses one at the time until you find the circuit thats killing your battery

SOURCE: bypassed wire harness draining battery?

With the ignition switch in the off position, check each curcuit by pulling out each fuse 1 by 1. Use a digital multi meter to check for current drain by pulling the fuse and touching the contacts with an amp meter, if it shows current that is the curcuit you need to pay attention too

Trouble shoot


I believe that's a Speed Sensor issue.

Diag:
1. Ensure mainshaft and countershaft speed sensors are installed properly. Disconnect mainshaft speed sensor harness connector. Using a DVOM, measure resistance between sensor terminals.

2. If resistance is not 400-600 ohms, replace mainshaft speed sensor. If resistance is 400-600 ohms, disconnect 25-pin PCM harness connector "B". Check for continuity between ground and 25-pin PCM harness connector "B", terminals No. 15 (Red wire) and No. 14 (White wire).

3. If continuity is present, repair short to ground in Red or White wire between PCM and mainshaft speed sensor. If continuity is not present, reconnect mainshaft speed sensor harness connector. Measure resistance between 25-pin PCM harness connector "B", terminals No. 15 (Red wire) and No. 14 (White wire).

4. If resistance is not 400-600 ohms, go to next step. If resistance is 400-600 ohms, go to DTC
P0720 (FLASH CODE 9) . Check for loose PCM harness connectors. Replace PCM with a
known-good unit if necessary.

5. Disconnect mainshaft speed sensor harness connector. Check Red wire for continuity between 25-pin PCM harness connector "B", terminal No. 15 and mainshaft speed sensor harness connector. If continuity is present, go to next step. If continuity is not present, repair open in Red wire between 25-pin PCM harness connector and mainshaft speed sensor
harness connector.

6. Check White wire for continuity between 25-pin PCM harness connector "B", terminal No. 14 and mainshaft speed sensor harness connector. If continuity is present, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary. If continuity is not present, repair open in White wire between 25-pin PCM harness connector and mainshaft speed sensor harness connector.

I have a draw on the battery on my 85 Toyota pickup it kills a fully charged battery in about 2 hours... Ive put a volt tester between the disconnected positive battery cable and the positive battery post...


Go to You Tube Video & see how to do a parasitic CURRENT
drain test

What you have done so far with a test light & volt meter is basically
doing nothing

You need an amp meter & a wiring diagram,then pull fuses one
at a time, to get to the circuit that causes the drain,then use the
prints to test that circuit for voltage drops

Power door cable replacement 2005 dodge grand carvan passenger door.


Sound like you having an issue with the sliding door. This is a common issue on this model. It can possibly be the cable or wiring harness. Its most likely the wiring harness because it gets strained a lot from repetitive bending. The harness is about $300 including labor, depending what location your in. The cable I could not find a price on because it looks like its a dealer part only.

This problem could be diagnosed easily two ways.
1. Swap passenger side for driver side harnesses and see if it works.

2. Use multimeter to test continuity between the ends of the harness.

- Disconnect the battery. I proceeded to unplug the harness on the car side which is behind plastic panel attached to the pillar between the front seat area and back sear area.

- Unplugged the harness on the motor/door side. Put your meter on ohms or continuity and test between both ends of the plugs all wires for continuity.
-If the passenger harness has the same is they you can access the cable there.
- Slide the door shut and open for each wire. There are approximately 8 or 9 wires in the plug. Most of the wires are smaller and there were 2-3 that are a larger gage.
-What ever wire is determined to not be working replace the broken link with new wire, soldering or carefully crimping.

Hope this gave you some insight!

Escort 97 - drains the battery with the key off and the heater blower and wipers stay on .


1st check the mechanical switch, mounted on top of the steering column, by checking continuity between poles.Also check the harness going into the switch as well as the main harness coming through the firewall. Check these harnesses by visual inspection for burnt or shorted wires and wires that are too soft and flexible.

Interminent battery drain on 2000 ford windstar


Check the voltage you are getting from the generator on the battery terminals with help of a multimeter. Check the continuity of the harness from alternator to the battery terminals.
If the voltage levels are below 13.0V and harness is OK, then get your alternator checked. (it may need replacement)

Assuming it will start again once it is warmed up, it is likely the battery is in poor condition/will not hold a charge. Unhook the battery once the car is running; if it continues to run, your charging system is probably OK, and the problem is likely to be the battery. If the problem continues after replacing the battery, you probably have a slow drain or short somewhere in the wiring harness. Best of luck on that one.
