Battery Light Problem, Help!

[Mr Papa Giorgio]

I recently took out my alternator to get it tested because I had a battery light on, I noticed the 3 wires from the harness were barely hanging on and soon after broke so I fixed that. but after getting the alternator tested and passed I put it back on. then I replaced the inline bolt-in fuse for the alternator. now I turned the car on and the battery light is still on. next step im going for is the battery cables(replacing). anyone else have these issues? thanks for your help. I really hate these electrical problems.

Why people remove the alternator from the car to get it tested is always a mystery to me. You can test the alternator while it is still in the car. In fact, that's often the best way to do it. These yo-yo's at the auto stores do not really know what they are doing so your alt. could still be bad but they say its 'good'. I wish I had a dollar for every time someone found out the alt was really bad although it tested good at the store.

You can do this yourself, Papa. Just get a voltmeter and measure the charging voltage at the battery with the engine running and a load(headlights on). Don't replace the cables just yet but do some more testing before you decide on the next step. Take your voltage reading and report back here.

thanks buddy, I will do the test in the morning so please check back around noon mtn standard time. ill be getting these cables from a stock ls from a salvage yard as well...good to have extra parts laying around. but yup I did do an alternator test in the past but I forgot what the readings were but ill check again and get right back to you as soon as the sun rises here in phoenix. I really appreciate the help.

hey landar, I did the test and found it running at 12.2....terribly low for an alternator output voltage test. so I thru my extra alternator in and now the problem is solved. im glad to cuz the positive battery cable looked to be a complicated item to replace. now I have to do the power steering system, tight steering. I know theres a solution for this also(rack and pinion solenoid) and also my new radiator is leaking from the bottom hose, luckily I have extra parts laying around so I can do a quick swap. thanks again.
