Jeep wouldn't start due to bad battery terminal connection. Jiggled connection, jeep started hard and required coaxing on the gas at first to maintain being started. Check enginge light came on and power brakes did not work. Next day, cleaned the terminal posts and connections and jeep started without problems however, still no power brakes. Checked all fuses. No check engine light now but still no power brakes.

Re: power brakes won't work
Was the car sitting for a while?The booster may be at fault.Caliper sticking?Fuses have nothing to do with your problem.It is a brake line problem.Could be a few different small problems.Easy to fix though.Hope this helps you

if you had corroded battery terminal look around the battery +ve terminal to see if there is another smaller guage wire that may have corroded through and fallen off. The big cable you cleaned powers the starter , the other wire powers the ignition and may need connecting.
Any issues with the ignition switch itself? They are mostly made of plastic pieces. With the exception of the actual cylinder. Also depending on how long you had the battery issue,it may have damaged the alternator. They tend to go hand in hand,unless caught early enough. The alternator gets overworked due to the weak battery.
try this.. disconnect the vehicle battery entirely, connect a 10 amp battery charger to the car connectors matching the terminal leads..and power the car with the charger..you should hear a hum or buzz in whichever relay or circuit breaker is bad.. replace this relay and the lights and stuff should work..the charger will not direct-short but the guage may go full over indicating a malfunction..or extreme load.. maybe a window switch might be fried..you should be able to hear any issues as long as power is coming from the charger only...repost findings..
Most likely you have a bad connection somewhere. Trace the battery cables and clean/tighten all terminals or try jumping to a different lug. You might also try removing the starter and jumping directly to the starter to verify that it is good.
you need to check the voltage at the battery when you have trouble. should always remain above 12 volts.
If not then the battery or the connections are bad. first test the battery right at it's lug terminals, then check the terminal connectors. battery or cable or connectors - def sounds like major voltage issue in the battery area!
Jiggle the wire connectors going in to the computer under the hood -- first check battery cables/terminal connections at battery -- beleive it or not, connection could SEEM good because you get crank & lights, but if it's faulty, loose, engine won't start - computer requires good solid voltage flow.. next check a fusible link very close to the battery off of the positive cable. check fusible link carefully. this could cause your problem for sure.
I wouldn't think catalytic converter, without it giving some indication that it was going bad, but without testing it is hard to say.
When it cranks and won't start, check for battery voltage to the coil on the dark green wire, with key ON. If you have power at the coil, it might be a bad coil. If no power to the coil, it could be a Crank Position Sensor or the Cam Position Sensor inside the distributor. If one of those is bad, it can stop the computer from sending power to the coil. Good luck.
first thing i would check is the alternator it should read 13.4 to 14.6 volts while running. if the alternator isnt charging than the vehicles computer is not getting the required voltage to run all accesories and engine parameters. i hope this helps
Bad starter or starter Solenoid. Grounded wire between the solenoid and battery or actually a bad battery. I've had batteries that were bad where everything worked until you went to start teh engine then it wouldn't turn over. There are 2 parts to the battery, 1 is voltage which runs the radio, windows, lights and such the other is Amperage which is needed to get the started to work. You can have good voltage but no amperage due to a dead cell. Disconnect the Negative battery terminal, connect jumper cables to a goo running vehicle, connect the positive cable to teh positive terminal and the negative clamp to the negative cable, this take your battery out of the loop, then try and start the vehicle. If the vehicle starts it's your battery if it doesn't then it is most likely your starter or Solenoid.
if the gps relies on the main battery for memory,that is why it is gone.the battery died
they should have a separate back up like a computer has a battery inside to retain the bios information and clock settings.
you should have a small secondary battery like a motorcycle battery,in parallel with the main battery isolated by a diode.
