What is a normal voltage draw for a 01 Cherokee sport , I currently show 9.5 voltage draw , I tried the pull 1 fuse at a time , no difference, did the same with the fuse box in the engine compartment,the voltage cut down by half when I pulled the IOD fuse, is the 9.5 draw correct? Thanks

 

Hmmm. Sounds like a technical question. That means it belongs in a Tech forum. But first, what kind of Cherokee? Some people seem to think that a Grand Cherokee is a Cherokee. Nope. Different car. If you have a Grand, your forum is here.

If you have a Cherokee, your forum is here.

 

I moved this to XJ Cherokee tech.

 

Not sure what you are saying (or how you are measuring) "Voltage draw"
The voltage is a "potential" and will be consistent weather there is a "draw" or not.

To see if your car has an electrical "leak" or is somehow drawing current when everything is off, you need to measure "Amperage draw" while pullng one fuse at a time.

 

Correct I went thru same thing 2 years ago with mine and if I remember correctly under .8 milliamps was ok. Actually that number is for newer model cars but I figured close enough.

 

hello , the voltage draw I found out is not the concern , but the amp draw which Iam coingto check tonight , will keep you posted thanks for responding

 

10-20 milliamps seems normal. Are having issues with the battery draining?

 

20 milliamps is the max I've always gone by. Keep in mind the interior lights will cause a draw if the door is open while troubleshooting.

That being said, hook a multimeter between the negative post and negative battery lead (with the meter on amps). Or use a test light. There shouldn't be enough current to turn the light on.

The only experience I've had in the XJ with a parasitic draw was the courtesy lights coming on at random times. I found a 5 wire splice (factory) under the passenger door sill trim. I had to cut them individually until the short went away, then reconnected the rest of them.

 

I put a volt meter in between the positive cable and post and show a 9.5 volt draw , I will switch to the negative post and use a amp meter . thanks

 

Measuring voltage between the battery post and the disconnected cable is meaningless (aside from 9.5-volts hinting that the battery is very low). You need to measure the current. You may see a few amps when you first connect the battery, btw. The #1 culprit I run into for high draw when shutdown is lighting stay on, especially the glovebox light. It could also be a bad diode in the alternator.

 

So I should disconnect negative side and check for amp draw then if there , is disconnect the alternator and see if it changes

 

Current is measured by placing the meter in series with the cable and battery. Measuring voltage like that will only tell you the battery voltage.

It's suggested to use the negative cable because if you touch the wrench you're using to ground while touching the battery, it won't arc.

Again, you could also use a (non LED) test light in line with the battery cable.

 

will check it out , thanks for the lead
