no juice, 87 Caprice

I have a 1987 Chevy Caprice with a 4.3 v6. It has 80,000 miles on it, it is my second car so it sits at times. When I opened the door the the interiour light and dinger seemed like it did not have enough juice (dead Battery) I tried to start the car and nothing, it did not crank over, no clicking of the starter, nothing. I figured it was the battery, but I checked it and I have 12 volts. know i'm woundering if it is the connections (wires) that are corroded? What all should I check? Any help would be great.

Thanks,
Matt

Fully charged you should have about 12 1/2 volts, so battery is low. Other likely problem would be corroded terminals.

pull the battery terminals and clean off the corrosion check between the bolt and the cable also this area is frequently missed when cleaning gm battery cables. after cleaning the terminals then try charging the battery. check to see if it will hold a charge by charging for several hours then unhook the charger and waiting 30 to 60 minutes, check the battery voltage it should be at least 12.5 volts. try to crank and check the voltage while the starter is engaged. if it drops below 10 volts while cranking replace the battery.

This very thing came up on the car repair radio call-in show I listen to every Saturday morning between 8-10 my time. Sam said 9 or 9 1/2 volts, but basically you are right on about making that point, and this is really something worth knowing and to always keep in the back of one's mind, or make a note of.

Wish I had a dollar for every time a customer used the phrase, "I don't know why it won't crank, all the lights work.....".
