My 73 Ranchero has an on again off again power drain. It will go a couple of months just fine , then overnite, battery will be dead. I know that these problems are difficult to pin point, but I am just looking for places to start looking. When the battery is hooked up, and i put meter on it, I can watch the voltage drop about a 100th per second. I am not real familiar with ANY electrical problems, so i ask, this, when i put my meter on the voltage reg, it is pulling 3.5 to 4, without the car running. is this right? I want to take this car on trip soon and would really like to get thhis resolved. thanx,Kelly

It has the clock and light. I didn't think it was those because when i disconnect the battery, it "sparked" like it it was pulling alot more power than that. I went ahead and took the battery back to Oreillys(just got it yesterday, and it was dead this morning). they charged the battery and checked the altenator and it was not putting out much,(there is a joke in there........anyway), i put a higher output alt in and it was putting out 17 volts........back to Oreillys and put in a new voltage reg. At this point, seems to have solved the problem.......stay tuned! Kelly

Just stating the obvious, but it could be an intermittent grounding problem. Make sure all cables between battery and starter are intact and not making connection with the frame, etc. I've had this happen, so I thought I'd put it out there...Al

Update......replaced voltage regulator, and upgraded to bigger altenator, problem solved. I put airshocks on her, hitched up auto trailer and went from Corpus Christi to Illinios to pick up a '69 Firebird. 2100 miles round trip in 59 hours. I just want to say that this is one bad*ss truck! Got 15mpg on the way up and 13 mpg pulling trailer and car on the way back......not too shabby. I had to keep looking back to make sure the trailer was still there, pulled real nice! Man I love my truck! Kelly
