Electrical question

My battery light started coming on a couple days ago. The first time it occurred was at startup and it took a rev to kick it in gear. Now it will come on when in the middle to upper RPM range (1200-2000).

After looking at the belt, I felt that it could very well be the cause and replaced it last evening with a higher quality belt from Autozone (3yr warranty vs the standard 1yr).

I have never had to remove a radiator hose to change a belt before, lol.

I could not tell if the belt has stretched because of the overall size of it.

I was wondering if there are any special features of these charging systems that I should know before I do anything next if the problem is still there? (I have not had a chance to drive it yet)

The reason I am asking this is because of my 1986 Buick Regal T. I had problems with it charging and it has a field enable that is triggered by the slight bit of ground potential through the battery light on the console. If that ground goes away, the altinator will not charge. And it has to be within a certain resistance range to be equal to the filament in the dash bulb. And it will not light the bulb when the motor is running. Quite strange ! and I just want to know if there is anything strange about these systems.

Thanks in advance for any help !

Mike

Sounds like an alternator to me.

I would start by taking the batteries out and having them load tested, and if they are good, take the alternator out and have it tested.

Good luck, I just Had a fuel bowl heater installed, Exhaust installed, (I bought it) and a E-brake cable installed, for a total of $324.

Still need to find the money to get a valve body, tranny cooler, and new batteries, lol!

Thanks for the reply. If the problem is still there, I will have the batteries load tested.

I just got my trans valve body yesterday from BTS. Looking to put it in this weekend. I should soon have my 31 row 6.0 cooler. I sold my Tahoe to support the needed mods to the Ex...

The charging circuit seems to be working fine now after replacing the belt. I also found a thread with troubleshooting charge light problems. I will keep that in mind also if it re-occurs soon.

Thanks again for your input !

If you had to remove the radiator hose to change the belt someone has put the wrong radiator hose on it . My 2001 was that way when I got it . Just went and got the right hose . Must be a hose for no A/C or something like that .

Hmmmmm

I will look into that one. Maybe a drive to the dealer will answer some questions.

Anyone else hear of such a thing?

I believe the stock hose goes through the fan belt unless you get the one for a dual altenator set up.

WOW !

I see that now. I looked and I see where it is not going now. That must be an expensive hose, and someone didn't want to pay for the correct part. I do not know if I need to replace it yet. The belt is already done now, lol...

Yea but if for some reason your truck eats a belt out on the road it makes it a much easier repair . You can actually get the belt on with no tools .
