Radio doesnt work, my wife called herself boosting of the car by herself and ended up putting the jumper cables on backwards and when she boosted it off the radio stoped working but the fuses are fine, any answers!!!! nissan altima 2005

the car as a wire connected to the chassis and he is descharging the battery. you have to go to a car electrician and look wall the cables to see where he is not isolated.

boost, hummmmm ?????????????
a charger with a boost button? (big shops have this)
or you mean jumper cable , jump started from a running other car?


my wild guess. is you always start fine, when jumper cable jumped.
this proves, the
battery in your car is BAD or is only discharged.
for 100 years now, same deal.
try a fresh battery off a good car.
works now, so ??? yours is weak or bad!

but started car , is the voltage 13.3. to 15v? a walfart $10 meter.?
no , then the charge system is bad (charge lamp on?)
note, i said system. not a specific part.

if the charge system is failing.?

1. bad battery. tha'ts right alts do shut down with battery bad. (open or shorted battery)
2. loose alternator pulley belt.?
3. bad alternator wires. connections.? or bad battery cables.?
4. scan the PCM most 2007 will report what is wrong with voltages and charge. scan it.

engine rpm way below normal at idle 800 is typ. good. 400 dead wrong.
battery cables bad.
battey cables lugs green with corrosion
someone put the minus cable far end to the wrong part>?
this minus cable has correct spot near the starter.
some fit to block others to stater , bolt or bell blots.
to frame is wrong, seen that , with lazy work.

Might need to check the main circuits for a blown fuse or fuseable link.
There is a fuse wire between the alternator and battery.

What are you boosting the fuse box for,? Are you trying to blow the vehicle up? Where did you learn to boost a car? The car that your useing to boost the car hook up one cable at a time to the batterys of both vehicles The car your useing for boosting hook up the ground to the battery first ,Then on the car that your boosting hook the ground cable to a the engine some where , To ground it, Not buy the belts or moving parts , Then hook up the positive to the postive terminal of battery in the car you are useing to boost the other car ,Hook up positive cable to positive terminal on car that you are trying to get started, If you don,t no what your doing get help from some body that has done it before, One wrong move you can (Screw) Up the computer in the car, End you might of done that (Allready)

Fuses?? Get a multimeter & check for voltage to plugs.

Use the engine mount on the front top of the engine,it's a convenient connection point for the negative cable when boosting.

sounds like maybe they put the jumper cables on wrong and shorted one of the wires

If you can access the starter from under the car, you can boost it there. Hook the negative cable to a ground point and carefully touch the positive jumper cable to the big terminal on the top of the starter solenoid. Be careful not to touch anything else with the positive cable. While touching the big terminal with the positive jumper, click your door opener.

Try boosting the van.If that works then you either need to clean the cables and battery posts or you need a battery.If boosting it does not work then you may need a starter or the cables to it have came loose,also the engine ground could be the culprit,if this is true then put your booster cables in this configuration;positive to positive and negative from the boosting cars negative post to your engine's block,find a good clean grounding point on the block and hook the clamp there.If the van starts then clean the factory ground point,replace the cable end,or replace the cable.Let me know if none of this info helps and i will give you more things to try.

bad ground cable,use a jumper cable from negative to alternator bracket, if it starts thats it.
