Hi I have an 87 Topaz and it will not hold a charge. I have used a test light in between the battery post and the negative lead and it flashes on then stays off....the previous owner had the alt. replaced and the battery as well. Do you have any ideas?? Oh and when I try to start it it tries to turn over and then it just clicks, tried smacking the starter with a wrench but still no go.......Any suggestions are greatly appreciated.

Well start with seeing if battery good or needs or has charge..also clean battery posts and connections..then check fuses in cab and under hood ..should after that have some kind of power or I indication of power..try that..then go from there..if I can help just message me ..good luck
must be a bad wire if you put a new battery and alternator in it. Are you sure the battery and alternator are good. One way to test the alternator is to run the engine and disconnect the battery [one post] while the car is running. If the car keeps running, the alternator is good. If engine cuts out and shuts off, alternator is bad
Sounds like you have a drain. Take off the positive battery post,and hook a test light to the unhooked positive battery cable. Then touch the end of the test light to the battery positive post on the battery,...if it lights up,with the key off,and all doors closed,then you have a system draw. Start pulling fuses untill the test light bulb goes out. When it goes out,use your manual to see what that fuse operates,and that will narrow it down for you. Good Luck!
Sounds like the battery is not holding a full charge...or not being fully charged by the alternator...(may be a corroded connection) Both of these are free tests at your local parts store...if both test fine...(unlikely) the starter has to be shorting out to drain the battery overnight...Hope this helps.
battery won't hold charge could either be bad cell in battery or you have a charging problem with your alternator, First I would chech your charging voltage should be around 14.2 volts while at idle, if ok then i would do a load test on battery and then a cell test, very possible could have a shorted out battery.
Hi. this is defiantly a slow or major drain that is occurring within this vehicle. Here is a test that you can preform that will help you find this battery drain so you can illuminate this issue.
--BATTERY DRAINAGE TEST PROCEDURE--
Using a 12-volt test light, hook one end to the negative battery post the other
end to the negative battery cable you just disconnected. The test light will glow
or "light" if there is a drain. If the "light or glow" is faint, that is probably
normal draw for the clock or computer. If the "light or glow" is bright, then there
is a large drain. That should be corrected. Now start removing and replacing the
fuses one by one until the light goes out; that one will be the circuit with the
drain. Remember to hold in the button in the door jam for the interior lights.
HI. you may have a battery drain issue that is sapping your battery overnight.
Here is the procedure I use to isolate a battery drain. Remove negative battery cable from the battery. Using a 12-volt test light, hook one end to the negative battery post the other end to the negative battery cable you just disconnected. The test light will glow or "light" if there is a drain. If the "light or glow" is faint, that is probably normal draw for the clock or computer. If the "light or glow" is bright, then there is a large drain. That should be corrected. Now start removing and replacing the fuses one by one until the light goes out; that one will be the circuit with the drain. Remember to hold in the button in the door jam for the interior lights.
Replace battery if it doesn't hold charge. make sure, that its not getting drained by something beeing on. You can do a fast test. remove negative batery terminal and run a test light between the negative cable and battery post. see if test light comes on. If it does, you have a draw on the system thats draining the battery. Then you will need an DVOM /digital volt meter and check how many amps you are drawing out of the battery. But its probably just a dead battery. Replace it. Good luck.
