Fuel filter change made battery light go on?
My "water in fuel" light came on yesterday so last night I drained the water out of the seperator and decided to replace the fuel filter while I was at it.
I put it back together and when I started the truck the battery light came on?
This happened a few months ago and I replaced the voltage regulator and everything was fine.
The only thing I can think of was when I had the fuel filter out there was a wire at the bottom of the housing that I pulled on (seemed like a good idea at the time). The wire had a small diameter rubber hose attached to it and there was a female spade connector on the end of it. No idea what that is or how or why it might make the battery light come on.
I suppose it is possible that the voltage regualtor went bad? I think it is only 2 months old and it cost me more than $100.
Is it all just a coincidence?
Could something else be bad that it frying the regulator?
Did that wire at the bottom of the fuel filter housing have something to do with it?
As always your expertise and knowledge are appreciated.
