Yes, they should both be green but I have seen batteries with red "eyes" that tested perfect. I would take it to Ford and have them checked. They are under warranty.OK....truck was parked in the garage all weekend. Got into it to go to work and no battery power. Charged one battery for 15 minutes and it started. The battery eyes are red in both. Should they not be green, Nothing in manuals??:dunno:
Went to Ford today and that's what they asked me but as you get old you do have some sort of memory loss.:doh: I swear i didn't leave anything on. They tested the batteries and did not see a problem. I did find out that the red indicates a not fully charge condition, not a bad battery. So I guess I'll just drive it and see what happens.did you leave somthing on :dunno:
New truck 11-07. 5400 miles.how old are the batteries? My last only 3yrs. Is your belt old? Of course if you don't have any further problems then I wouldn't worry about it.
I had a similar scenario with new batt(s), but kept discharging. Did some checking and found Idler pulley (keeps tension on serp. belt) was wearing out. Belt slipping, so alternator wasn't charging adequetly- strange thing was the belt didn't make any noise (squeal/chirp).
