69RavenConv 301 Report post Posted February 23, 2012 its a 4month old battery...but, yea after sitting, it reads 17.5vmaybe the alternator is over charging it... Yeah, that could be a problem. That much voltage isn't good for a battery. Quote Share this post Link to post Share on other sites
Boss302 22 Report post Posted February 23, 2012 whats a good voltage regulator to get..any suggestions? the current one has no names,numbers..just silver box approx: 2" thick and 4" wide/tall it looks old, probably atleast 10yrs...maybe the end of its lifespan its not a show car, so need to be a special version or all shiny..etc but if its a few dollars or $10 difference, i wouldnt mind. ....is there a safe way to test the V.Reg.?

danno 128 Report post Posted February 23, 2012 If you really are at 17 volts, there is a chance you could blow up your CD player. I would unplug it until you get this figured out. Also, if you are at 17 volts and been there for a while, you probably fried your battery. That could explain why it is not holding a charge. You have 2 problems; one is the overvoltage when the motor is running, and the other is the discharge while the motor is off. One thing that can happen often with this sort of problem is a bad ground or other bad wire connections. Remove the ground wire from your battery to engine and clean the connection points with a wire brush real well. Do the same with the wire that connects your engine to the chassis, it is in the back next to the firewall. I would focus on getting the correct operating voltage, then take your car to any shop and have the battery load tested. This will tell you if the battery is still good. Regulators are cheap and easy to change, so I would try that after you get connections cleaned. If that does not solve your problem, it is going to be a lot more dificult and we will cross that bridge when we get to it. Quote Share this post Link to post Share on other sites
