    IF AN ALTERNATOR IS ONLY SHOWING WHAT YOU SAYING WHEN INSTALLED THEN IT IS NOT WORKING.IF YOU HAVE POWER AND GROUND TO THE ALTERNATOR,THEN YOU NEED TO HAVE POWER TO THE REGULATER TERMINAL MARKED "I" OR "L".IF YOU DON'T IT WILL NOT CHARGE..YOU MAY ONLY NEED A BULB IN THE DASH. BUT IF YOU CAN FIND A SOURCE OF POWER THAT COMES LIVE WITH THE KEY TO PUT TO IT 'IT WILL CHARGE OFF OF THAT.

You may have a short. i would probably check the ground strap from the engine to the frame. they can rot out. my 98 chevy is garage kept with 65000 miles and it looks terrible. the rest of the truck looks new. other than that. make sure the battery is good. and possibly take it in and get it checked before more damage happens.

My 1998 chevy dually has a 7.4 engine and it keep blowing out alternators


Best course: Install a LARGER CAPACITY aftermarket alternator. Also, if you have a car stereo system with a subwoofer, MAKE SURE YOU ARE USING AT LEAST A 2.5 FARAD CAPACITOR AT THE INPUT OF YOUR AUDIO AMPLIFIER. (Not using a capacitor with high-wattage sound systems can literally blow out alternators!)

I have a100 amp alternator and putting 4-130 watt off road lights and the vehicle on it 98 Chevy blazer


Do the maths and talk to an accredited auto electrician but I am sure that the alternator will be too small for what you want to do
the formula is I(amps)= P(watts) divided by volts
4 lights at 130 watts each =520 watts divided by 12 volts =43.3
amps extra for the alternator to handle. AS most alternators currently run at 90% capacity with normal vehicle operations you will need a bigger alternator. I would consider using a band of LED lights as they have more light than the 130 watts will provide and use just a few amps thereby not requiring a new alternator. Do your home work .the price of a new alternator and wiring ,relays etc against the LED lights. More light , lighter bracketry and no relays.

Alternator last night went to13 volts put a new one on today started pickup it showed 14.2 volts drove about a hour anf it feel to 13.5 now its back to 14.2


You got a bad regulator in the alternator,maybe

Also check diode leakage (current ripple)
& grounds

Those alternators have been rebuilt & you still have
other peoples old parts inside them

After that you need a wiring daigram of the circuit to see
where the regulator control comes from

Possible failed battery all along

If the alternator is plugged up it blows a fuse in fuse panel. Also turn signals


alternators have built-in voltage regulators. if the voltage regulator goes bad, it could over-volt, resulting in blown fuses or blowing the cap off the battery. you can use a voltometer/multitester to test the power at the battery. a running engine should put out about 14-15 volts (14.6 is quite average) at the battery terminals. if your voltage is higher, the alternator needs replaced.

Charge light was on and alternator was overcharging. had alt. rebuilt and new voltage reguator, not charging now. only getting 2 to 3 volts are the charge fuse beside battery. new voltage reg is electronic...


There is a fuse under the dash that is the same one that operates the fuel gauge, if it blows the alternator wont charge. If the fuses are good I would take the alternator off and get it tested. Hopefully the rebuilder will warranty it. I would also make sure the new regulator is compatible with the old type regulator system. Most large auto parts stores can test alternators, and they normally do it free.

1996 FORD THUNDERBIRD ALTERNATORS KEEP BLOWING


A bad ground kills alternators and charging at full capacity too long does them in. The charge rate read with a meter should be 1.6 -14.2 No higher or lower. The lower the voltage the higher the ampereage. So @ 10 volts the alternator is working real hard and that causes the alt. to overheat enough to damage solder connections. Hence,the term "slinging solder. The bad ground, battery or alt, causes output spikes and regulator damGE. cHECK ALL YOUR CONNECTIONS AND THE VOLT RANGE OF ALT OUTPUT. iF IT'S CONSISTANTLY TOO HIGH, YOUR BATTERY SHOULD BE QUESTION.. The voltage should be low after cranking and starting but statart climbing after a minute or so as it recovers.

80a fusible link 95 4runner keeps blowing


You either have a short somewhere, or the alternator is over charging. What does the volt gauge read before it blows, if you don't have a gauge, get a volt meter and test at the battery. Anything over 14.5 will blow the link.

I HAVE A 1985 K30 6.2 DIESEL 4X4 MILTARY PICKUP


The reason the fuse blows/melts is because there is excessive draw. The other alternator could be wired wrong. Check to make sure the wires are correct gauge.
