Has To Be Jumped Every Start
I have a 1990 Olds 98 regency, and I have replaced the battery, altinator, plugs and wires, and it still needs jumped everytime I try to start it. Does anybody else have any idea whats wrong with it?

Re: Has To Be Jumped Every Start
You must have an open circuit somewhere draining the battery.
Or your connections are not good. You could have a bad battery cable. I'd Check for voltages with the car off and while running. On the battery and on the starters wires. If you have an aftermarket stereo sometimes these(if not installed properly) can drain you system. Hope that helps, and Welcome to AF.

Re: Has To Be Jumped Every Start
Thank you for the info. Now she's telling me the car will start if it is started everyday. But if she lets it sit just for one day without starting it, it won't start and needs jumped. Like I said before, new battery, new altinator, new plugs and new wires. What do you think?

Re: Has To Be Jumped Every Start
Check the battery voltage with the car off, should be about 13.4 vlts. With the car running it should be around 14+ at the battery terminals.
Also like I said before check all the connections at the battery and the alternator, and the starter wires. If any of these are loose it'll give you problems. But since you have replaced the things involved, must have a short circuit somewhere in the electrical syst causing the drain. Good Hunting!

Re: Has To Be Jumped Every Start
I also suspect something is draining the battery. See if you can get your hands on a multimeter that can check DC amperage. Most meters have this capability. Disconnect the negative battery cable and set the meter to measure up to 10 amps. Place the black meter lead on the negative battery terminal & the red lead to the negative battery cable. The meter reading will spike a little then drop when the PCM goes into sleep mode. At this point the reading should be less than 1/10 amp. Everything needs to be off while doing this test. If the reading is to high you can pull fuses to isolate the circuit that is causing problems.
