Voltage spiking! - 1/9/2006 11:31:02 PM    PTT   Posts: 18 Score: 0 Joined: 9/7/2005 Status: offline The culprit is a 1995 E150 Conversion Van w/5.8L and E4OD showing 187k miles. While driving at night I noticed my lights flare up and the battery gauge needle peg out to the right (max). It only stays like this for a few seconds and then everything goes back to normal. It's intermittant and may not happen again for a couple of days. It just happens all of a sudden out of the blue! No other symptoms. Any ideas appreciated! Thanks. Post #: 1

Do new alternators come with a new regulator as a rule? Whats a good price on one? I think it is a 135 amp unit. Thanks! (in reply to boflaade) Post #: 3

I live in a rural area of Canada so prices unlikely relevent to where you are. I believe the 135 amp is standard. Check out the battery while your at it. I could have been damaged if overcharged.
