Ok replaced alternator. Batteries and Alternator read 25V with truck running when using a multimeter, when i hook up a tester it says 12V at batteries and LOW VOLTAGE 11.4V on the charging system. FICM reads 95V with ignition on and truck running. Should i be concerned?

I think you're reading the meter wrong.

No I'm not. I use multi meters for a living. It could be faulty but doubt it.

You do know that you only have a 12 volt system right... It's two batteries in parallel.

Either you're reading it wrong or you have one battery hooked up wrong and made it a 24v system
