New Alternator brushes, however battery light doesn't come on

Hello, just replaced new set of brushes, however battery light doesn't come on at start, engine isn't started.
Old brushes put the light on and then off as engine starts, so I know it isn't wiring.
Could the brushes be wrongly connect..i.e.two bushes internally connected wrong way..did I megga on them, and seem opposite to old on from rectifier to each bush....or do new bushes take a while to settle?

Using a mega on rectifiers can damage them
you should take the alternator to an auto electrician for a proper bench test

You can get just the bushings at autozone, checker, napa auto part stores for about $30.00 to $35.00. You can replace them yourself or take the vehicle to the shop.

That control arm is technically un-servicable and by the end of the day after finding something,then trying to wrestle these in where they work properly,probably the best, easiest and cheapest in the end is to replace the control arm.

This is 100% of your troubles. Connecting a battery up wrong can cause a handfull of problems, I would start with making sure that there hasn't been a fuse blown both under the dash and under the hood as well. Electrical surges like this can very easily burn up your cars computer as well.

If it is more than checking the basics, fuses and such you might have to have it taken to a repair shop for an electrical diagnostic.

Good Luck, I hope this helps some.

2007 Chrysler Aspen - My battery light came on and stayed on, on my drive home from work. Home about an hour and started car, just about to leave and car died. Click click. Won't start. Get a jump, starts...

The battery light indicates that your alternator is NOT charging the battery. Your alternator is not working; it could be one or more of several reasons:
1. the brushes may be worn out in the alternator that supply power to the field windings. This is a fairly simple and inexpensive fix for a do it your self job, but automotive shops seldom if ever will do this.
2. Other things like diodes or an open winding could be wrong with the alternator; in which case you should just replace it [and while you are doing so, replace the serpentine belt]. See video enclosed
3. The battery could be bad because of the deep discharge it has experienced.

Short in wire from battery to starter or cylenoid? sometimes it will turn over other times not

I had my ford 91 ranger checked and both were good, plus alternator was in the green? But kept killing batteries and would not start without a jump. I replaced solenoid, starter, and battery. Finally removed the alternator and the BRUSHES were making contact just enough to keep my truck running, but when lights or any other accessory was used the truck would quit. New alternator and starts every time and can run all accessories without problem. Check the brushes on the alternator.

Hi my toyota has probelms starting in the morning, my headlight beam strenght varies between weak and strong throughout the day, and this moning my hazard lights came on and would not go off and would not...

Sounds like the starter battery can't hold the charge from the alternator. A 1 hour highway drive should charge the battery enough - if it's the same the next morning it's up for replacement. Assuming there are no lights, radio or other devices on in the car during the night.

If the battery has been recently replaced - the alternator might not supply enough current anymore. In this case alternator brushes might need replacement or the voltage regulator has died. Usually the battery indicator lights up in this case. The battery indicator light can be checked by turning the ignition key one notch so all lights in the dash light up. If the battery indicator doesn't light the lightbulb might be dead.

Hello: Don't know what year/model. You may have shorted the alternator out. With the engine off, take a dc volt meter and check voltage at battery, the start engine check voltage at battery again if it is the same or a little less than the first reading the alternator is not working

Low battery voltage light battery won't hold charge 2002 S60

Yup, time for a new alternator. Most models have the regulator built into the alternator, so it makes it a little bit more expensive - but it will resolve your problems. If you are driving at night with a load on your charging system (lights and radio on), you will probably notice you have dim headlights. If you don't change it soon, you'll end up having to replace your battery too.

Hi, Battery light coming on occassionally. Battery is new. Any ideas, could the alternator need new brushes or rectifier? Thanks

i think you are right...the alternator may need a new set of brushes. battery light coming on and off is an indication.

a busted rectifier would not indicate an on and off light but rather a steady on light. but it has 6 diodes and one busted diode would do the same. on and off battery light depending on the load present in the system.

tnx 4 using fixya,
