Trouble lights

I could use a bit of advice regarding my dash trouble lights. A few weeks ago three bulbs started glowing faintly at the same time. They were the "water in fuel pump" the "battery" and the "A/T" light. two are side by side so I thought perhaps the light was just bleeding through. Anyway, instead of glowing faintly, they are on solid now. I have drained the fuel pump and have checked the tranny fluid and the battery is charging just fine so I am out of ideas., Anyone?

Replace your alternator.

The charging system seems to be working great so I believe that indicates a healthy alternator.

If those three lights are on when the engine is running, you have a problem with the charging system.

alternator X4
Check the wire on the back and the battery terminals first...
Mine was flashing the lights on start up and once and a while...never had a starting issue both batteries are 12.5V with motor off. Start truck and 12.3V is all the alternator could put out.
just had it rebuilt $224.00 including the oil seal for the vacuum pump L300. Installed myself.
Now it puts out 14V at fast idle as it should.

Thanks to all for your assistance. I have an alternator being shipped to me and I hope to be back on the road by the weekend, thanks to Mardy as well.

Are you getting your alternator from Rising sun imports? If so it is a good replacement but before warned the stock connector is not the same. If you pick up a 2 pin weather pack both ends and install the connector before installing the alternator you will save yourself some grief.
Good luck
