I starter my 54 3100 a few weeks ago and let it run after a cold winter here in NJ. It ran fine until I shut it off about 10 minutes later. I then went to try and start it again as I usually do and - nothing. I turned the key to on and all the gauges come up and give a reading. If I press the floor button or turn on the headlights the gauges drop down to their lowest setting. If I turn the key off and wait 30 seconds or so, I can turn the ley to on and I get the same results. I had the battery on charge for a few days but there was no change. I have not dug any deeper into this but just to let you know, the battery is only about 9 months old. Any thoughts would be appreciated. I am the third owner of the well taken care of 3100 with just 54K miles.
