New alternator, new battery, new terminals, good working starter… car still acting up…?
battery tester January 25th, 2009I had my alternator replaced & got a new battery w/ new terminals, had my starter tested and my car still is showing 13ish on a battery/alternator tester and drops to 12ish then jumps around between 12-13 when anything is on. It then started jumping and cutting out after I stopped, backed up, and turned today so I went to have a diagnostic ran and I then replaced the ingnition coil. It ran fine with no change in the voltage for a few hours then started to jump and cut out again. Anyone have a clue what could be going on? It's a 01 Kia Spectra.
Forgot to add this but I have new belts also .
The thought comes to mind that you may have a bad Alt gage. When you say new terminals are you talking about completely new cables? It's possible you have corrosion inside the insulator on one of the cables. I will always replace both the positive and negative cables when I replace the battery. This way I am assured a true connection between the battery and ground. Just a thought.

Voltage regulator?

It could be a few things, hopefully its a fan belt you could also check the ground wire between the engine and the bodywork to make sure the contact is good.

First of all it is a KIA, no offense but they are very disposable. Some garages haev a code for them that says "replace vehicle and retest". If you have a loose ground wire or a bad terminal, it will cause that problem. That usually occurs on the solenoid terminal or even the battery ground run. Get a good flashlight and start with the battery, checking the posts and the wres. Let the car run and see if lightly wiggling the wire causes a break in engine performance. Continue on down. This would be my first step and the most logical.

it sounds like it is time for proffesional help. some thing is intermittant and that makes it hard to find. you might try checking all ground wires especially to the body and computer. or try jumpering a ground and a hot wire from the alter nater to the battery while watching the voltage on a volt meter if this calms the charging system down look for bad connections.
