the battery in the jag im workin on looks like a bus battery,the car was dead...Ijumped it...it took about 10 mins. charging b4 it would start...drove it 4 about 5 miles and all my lites went out[inside car]started runnin then stalled....alternaters bad...is the new battery u bought 4 it the rite one?try checkin you alternater ????

There is a 140 amp fuse in PDC. fuse box on drivers side next to battery,make sure its not blown.

the only three things i can think of is youve either got a bad alternator ( yes if its a remanufactured one its possible) your battery is wasted (replace), or the wiring isnt correct and the alternator isnt providing to the battery.

First you can not test an alternator by disconnecting the battery cable. That is what we did back when cars had generators. Today you can fry the computer and alternator running the engine with the battery cable off.
Meanwhile, I would look for a fuseable link or main fuse problem. The alternator circuit may not be connected to the fuse box and battery.

Take it to local parts and have them test alternater, usaully free test probably bad alternater. There is a good chance the blower motor went out. Probably need to replace as well

you have a faulty alternater there is a speed sensor in the alternator that is linked to the power steering if the alternater isnt charging the steering wont work either replace the alternater and all should be ok

your alternater is shot bring it it to napa and order a new one its a common problem

hi, if the battery light is lighting up then this indicates the battery isnt charging properly so what you need to do now is check that the alternater belt is tighten correctly and not slipping check all wires going to the alternater if they are ok then the chance are the alternater needs replacing.

Let me know how you get on or if you need further assistance ok

Hi if the battery light remains on whilst driving this indicates that the battery isnt charging at full capacity this usually means that the alternater needs replacing but its also worth getting the battery tested as this could also be the problem but the chances are the alternater needs replacing.

Let me know how you get on or if you need further assistance ok

Drive the car to the auto parts store and have them test the battery and alternator for proper charge.  You probably just bought a dud, even though they are new.  Doesn't happen much but does happen.
