You have a wiring problem. Check really close the small wire on the solenoid. This wire is located on the opposite side of the solenoid that the big wire going to the starter is on. These are usually found corroded and/or broken inside the jacket insulation. You can run a jumper wire to test or use a tester.

How can you constant the volt of alternator?
The voltage regulator has the job of making the voltage 'constant'. In most modern vehicles the regulator is located in the alternator, in older models the regulator is located separate. If your voltage is jumping around a lot then you either have a problem with the battery (batteries stabilize the voltage also)or the charging system (and probably the voltage regulator)
1996 Taurus battery charging light came on replaced the alternator and the problem seemed to disappear day later light back on battery not getting charged bad alternator?
you may have a bad battery or a bad voltage regulator
Replaced the battery on your 2000 ford explorer and the battery light is still on could it be your alternator?
Most likely the problem is your alternator....the battery light actually does not monitor battery condition, only the charging system. I'd check the voltage regulator and the fuses first. The fuses are the cheapest fix and the voltage regulator will run about 25% less than an alternator.
1993 Chevy pickup battery dies if not started regularly is there something drawing on the battery?
I have a 1993 silverado that was doing the same thing, and the problem turned out to be a bad regulator inside my brand new alternator. Ireplaced it and went ahead and replaced the battery, I haven't had the problem since! Hope this helps.

Where is the Voltage regulator on an 89 escort gt?
I have a 93 Escort GT that I am trying to locate charging issues with. I just replaced the alternator (which doesn't seem to be the problem). The regulator was located inside the alternator in mine. So it came new with the alternator (whole thing $130 + core). In some though, it is bolted to the outside of the alternator and costs about $70. Take the alternator to any parts store and they can test it to tell you if it and the regulator are working. Don't have them test it while it is on the car. Mine works off the car, but will not work when put on the car. I have some type of wiring issues.
Why would your battery light stay on after you have put in a new battery and alternator?
The battery light comes on when the alternator output voltage is too low or too high. You have a wiring or regulator problem.The battery light comes on when the alternator output voltage is too low or too high. You have a wiring or regulator problem.
New voltage reg and alternator F150 1982 will not charge?
In order to see if the Alternator is actually working properly you need to by pass the voltage regulator to see the actual amp out put for the Alternator. If you don't, you may not find the source of the actual problem, ie faulty regulator. Also, if the fan belt has turned slick on the underside of the belt, it will not grip the pulley well enough to allow a charge from the alternator (have found this to be common mis-diagnosis by many shops in that the fan belt is actually burnt underneath but you can't see it slipping on the pulley therefore the alternator isnt' charging and they replaced alternator, regulator, and continued to not fix the problem until I found it to be the belt ), otherwise, check your wiring on the alternator and regulator, and go from there. Make sure you use an actual machine that tests the output on the vehicle. Good luck.
Why is Chevrolet Cavalier not charging?
alternator needs to be replaced. battery also might be a problem due to the alternator not charging it
Why does your 2000 buick regal die out while driving?
could be alternator? On 2001 models there is a problem with the fuel pressure regulator that causes this. I suspect there may be a problem with the 2000 models also. Mine was replaced for $70 over two years ago and I have not had this issue since.
What is the problem when your change the alternator and its still not charging the battery?
Obviously check the battery. Anyway, if the alternator, battery, and wires connecting them are good the voltage regulator is next on the list.

What would cause the fuel level alternator stop light and washer fluid warning lamps to come on and blink along with the buzzer on a 87 Mazda 323 SW but only below 2000 rpm and fine above 2000 RPM?
I found this on the web: http://www.mazdaforum.com/m_29848/tm.htm The problem may be the alternator or the regulator. Must I replace the entire alternator if the problem is the regulator? Most modern alternators have the regulator built in.
