where to start have replaced the alt.4 times due to dying they where all rmaned just bought a brand new one and put it in .guess what no charge at all.does anyone have any idea what could be doing this to me.have also had the rpm gauge going though the battery light came on.any info would be great thankyou

 

when you take the alternators back are they bench testing them? Do they pass or fail?

 

You need to check your wiring.
Your grounds, everything.
We also need to know if it is a DI or DII.

 

its a 95 disco1.

 

how is the fuse and the wiring.

is it connected.

 

Dont know if this may be the issue, but I recently bought a 1998 discovery I and the reason the owner was selling was because he couldnt keep alternators on it. The problems started when they changed the waterpump at a local garage. 3 alternators later and $1500 still wouldnt charge. I brought it home acter I bought it, popped the hood and noticed that the sepentine belt was put on wrong! It was tigjt just enough to keep it from mot squealing but woulcnt let it charge properly. This allowed me to buy this ride for only $1900 and is running like a top .

Just like glovings said, it is very very easy to route the belt wrong on a DI.
It will look right,everything will turn, but it wont be right.

 

Yeah. It looks logical when you take it off. But when you go to put it on it's a different story. I had to resort to a diagram and do it by the numbers. ;^P
