Tip & How-To about Jeep Grand Cherokee

Computer Fix

I read a tip about taking the positive side of the battery loose for an hour and then hooking it back up. This tip seems to have corrected my Idle problems and from now on for the cost of 1 hour I will try this before I get angry. What a Great Tip. I have a 1997 Grand Cherokee but I would bet this could help some other 'Non Mechanics' to save them some Grief.

How to hook up all the wires back onto the battery since I'd just bought a new battery and I'm trying to hook the battery back together

Keith, If you have the correct battery( size and correct cable terminals) you may have to give the wires a little tug to give a little more length, stretch so the wires are easier to put on. The wire with the red end goes to positive on battery. If battery in trunk the battery connections face out. I will put links below, hope they help.

toyota 4runner ran low on oil and now won't start

Throttle body position sensor (TPS), JUST locate the throttle body and you will see an electrical plug, RIGHT at the throttle butterfly, check if it's LOOSE or if there's anything WRONG with the WIRES, and go from there.
Normally, it will have like 4 wires, not sure about the color, but 1 is constant power, 1 is output signal, 1 is IDLE/Wide open throttle SIGNAL, and the LAST is ground.

Use a Voltmeter, hook the NEG-(black lead) to chassis or BATTERY NEGATIVE. The RED lead is probed into any wire to check for any voltage. ONLY perform this check when you have Ignition ON, means that you have power, but engine OFF. Do not take hours long you will drain the BATTERY.

Power wire will either be always 5V or 12V constant.
Ground will have ~0 Voltage.
OUTput signal wire will VARY as you work the throttle, start at 0.5 "ish" and 4.5V "ish at Wide open.
The idle switch signal should switch between maximum and minimum value as you work the throttle BACK and FORTH.

IF NT working, look for a new part. IT's TOYOTA should not be EXPENSIVE.
FEEL FREE TO DESCRIBE what you find to me :).

Alternator not charging battery

voltage regulator, it may be internal in the alternator, if so then you can get a bad one, take alternator off and autozone or advance auto will test it for free. if it is external then it shld be fairly easy to replace note:if its external it usually has a cable running from the battery, and another cable running to either the fusebax or alternator itself

Hi, I have a 2008 Pontiac G5 and I accidentally kept the lights on all day. Since I only have a positive (red) connection, I ground the negative connection to metal as well as the other car negative connection to metal? Please Help.

sounds like you are on the right track. Hook the jumper cables up to the dead car first. The red cable should go to the jumper terminal as you mentioned and a good place to hook up the black cable is the bolts on the strut tower.

then with the other car running hook up the red lead to the cars positive battery cable and then the negative to a good ground. Let the two cars sit for about 5 to ten minutes to give the dead battery a chance to charge.

Once the dead car is started let it idle with the lights turned off for at least 45 minute to an hour or drive it for the same amount of time with the light on (I assume you will be driving in the dark) or if its day time drive it for 30 to 40 minutes with the lights off. This should be enough time for the alternator to charge the dead battery.
