battery reads 14 with jumpers on and keeps power. gives out 12-19 but A soon as I disconnect the jumpers the battery loses voltage and decreases rapidly.

Brand new wires battery and starter.

Measure the output directly from the alternator (should be close to 14) and then separately measure the output at the battery. The two numbers should be pretty close. If not, it's probably you're wiring. If your battery is reading 14 with jumpers I'm almost certain your alt is good and you have a wiring issue somewhere between the alt and battery

When I tested the alt I kept getting diffrent numbers it was jumping around every second between 12 and 19 and At times it said 1-.--.

Battery reads 9 atm with engine running and no jumpers but the voltage is running downward real fast.

I too think it's a wiring issue seeing I put in New ones I could of screwed up somewhere. I am just having difficulty finding where the wires run from the alt to the battery.

Oh also I have no power to my wipers or radio..

Could this be a cause of any of it? New connector only had 1 post i have power though the top bolt as well though.

No power to cig lighter either.

Sounds like you got more going on than just your alt/battery...NOGGIN' POKIN' TIME

Make sure your power and ground wires are in the right spots on the battery, starter, and alt. I mixed up the two once and it caused the exact problem you are describing.

chrispl57

yea they are :/.... gonna take the alt off tomorrow and take it to an autoparts store to be tested.

chrispl57

So yea...just remembered when I hooked up the battery I put it in backwards temporarily... Apparently that kills the alt and some electonics.

Must be my problem.



Damnit...

As in crossed the cables? Ouch. We've all done something of the sort. I once left a rag in an air intake tube on another vehicle and couldn't figure out why it kept dying. I feel your pain

Yuppers.. I put the battery I'm facing the wrong way and popped in the cables. On well I guess found a a
Remaufactors acdelco for $57.

Before you replace that battery, test it. Disconnect EVERYTHING, then measure the voltage and watch what happens. If the voltage is dropping with everything disconnected, it's shorted internally and it's toast.

If that's the case, replace the battery and try again. You might be okay.

But, even with the battery replaced, you may still have other problems that were caused by the reversed polarity.

Why did u replace wires,battery,starter?
Which wires specifically?
Blue is on the right track,test, diagnose, then repair or replace as necessary.
