Whats your volt guage show when the truck is running?


I just replaced my alternator, its was making funny noises (bearings worn out). Last one that made noises like that went critical and started on fire, so I decided not to let it go that far...

how long did you run the engine for when you started up your truck? Starting your truck takes alot of energy. I wouldn't start my truck up to just let it run for a couple minutes. YOu probably just need a new battery.

My meter reads 15 volts, just past the 14. It can go down to 12 volts when i have the system full blast at idle.

I would let the engine run for about 5 minutes then turn it off for 5-8. I didnt have this problem when i got the system last May, or January for that matter.

Jump your truck and let it idle for a bit. Rev the engine and if the amp meter bounces up then your battery is out. Or have the motor running and unplug the battery and if it dies its the alternator.

how many watts you runing again?

i know when i upgrade my alt its going to be the 220 amp from iraggi alt. maybe more amps depending on the cash flow at that time

oh yea i would start with a yellow top and just see if that fixes your problem. then if your alt goes out you can go a couple days on that yellow top (i did)as long as you dont play your system or run the a/c or any other dependent things

that's a great decision. im running the same unit on my truck and it has performed flawlessly.

If you truck shows 14 + volts then it's your battery. If it was your Alt. you would be getting 12 volts and less when running.

I've done it a million times. I guess I'm lucky. Its just like running your car with a dead battery.

Negative.
Im running about 950 rms, 1900 peak to the subs. About 500 to the mids and highs.

I belive autozone tests them for free, just have to remove it.

Also, what condition is your belt? it's not as prevelant as it used to be, a slipping belt can cause charging to not work well.

Thanks for the information, guys.

As for the belt, I dont know what condition its in, Ill try to check it out tomorrow.

thanks again.
