Re: THe NAC Lots-O-Post Thread

Im still cooking mine up, not ready to release this terror on the world just yet
 
Re: THe NAC Lots-O-Post Thread

So my cousin has a 99xj. Last week he said it seemed like it needed a new alternator, and what he described sure seemed like it. Voltage was down to nothing, radio was acting goofy and headlights hated life. So, like it wasn't charging. Wednesday I changed the alternator, got it started with the last bit of juice the battery had, but the voltage was still nada, headlights were shit and radio wouldn't do anything. When I revved it up a bit it had a miss. Let it idle for a bit, voltage didn't move. Shut it off, it was dead and I gave up for the night since I didn't have jumper cables. I'm heading back in a few and gonna bring jumpers and a multimeter...any idears of what I can look at or look for?

Thanks queerville

My guess would be that since the battery wasn't be ing charged then it went bad and won't take a charge. Either that or you forgot to hook the wires up on the back of the altinator. Ask me how I know that.

Re: THe NAC Lots-O-Post Thread

Wtf how did that happen?

But I did that in my MJ just installed it but never hooked it up then ran the batt down to nothing over the next two weeks. And ruined it. Now it won't take a charge.
 
Re: THe NAC Lots-O-Post Thread

how olds the batt? also when there dead below feezing it normally ruins em
 
Re: THe NAC Lots-O-Post Thread

ha nice. no, definitely have it connected. felt the one connector snap in place and then the other one has the nut on there nice n snuggie like. maybe i'll steal a battery out of one of their other cars for a few and see if that makes a difference. still doesn't explain why it's missing, but i guess that's more likely an unrelated issue

didnt look at it too close because it was dark and raining when i did the alternator, but i don't think it's too new if i had to guess.
 
Re: THe NAC Lots-O-Post Thread

bring it to advancedt or the zone and get it tested, check all the conections n shit. IIRC my 98 started acting funky before the alt died to
 
Re: THe NAC Lots-O-Post Thread

Might be a shitty connection or blown fusible link or fuse, forget which is used for the alt b+ on 99s

Measure voltage at both alt field terminals. One should be battery voltage, the other between 0 and battery voltage. 0 means full charge rate commanded, battery means no charge commanded.

Measure the voltage at the b+ terminal. Should be 13.5-15v or so.

Measure voltage from b+ terminal to battery positive. Should be well under a volt, preferably under a few tenths of a volt.

Measure voltage from battery negative to chassis. Should be under a few tenths of a volt, may be a little higher when cranking and charging.

i understood what's in bold :laugh:

thanks though I'll try to figure out whatever all of that was
 
Re: THe NAC Lots-O-Post Thread

B+ terminal = big ass bolt terminal on the alternator (the one with the plastic surround)

Alt field terminals = the two small terminals in the alternator connector that aren't bolted directly to the metal housing.

Also.

That guy engineered the Viper. He took the biggest small block Chrysler made, added two cylinders, and put it into a body designed by a 12 year old whose only two dreams in life were to design an awesome car, and to hunt bears with a rocket launcher from space.
That's how the Viper came to be.

I didn't know Carmelo designed the viper.
