2006 Pt Crusier P068a code is all im getting with key dance.. dont know what that means but my battery light is on and car boggs down when i give it gas. thinking catyalic converter?? any help please


Hi,maybe the best place to start is the alternater,if the red light is on and when you try to rev up the engine it gos to die,one other check is to put a multymetre on the battery it should be around 12v but when you rev up the engine it should go to about 14v,so try reving if it stays the same or gose lower the could be alternater.
all the best

My Mazda sometimes does not start right up it clicks first then I have to turn it off then start it up again then it starts what could be the problem?


I think your starter solenoid is getting borderline flaky. It has a copper disk inside that makes contact between the battery cable and the starter motor itself, and that copper disk gradually burns away & corrodes. You get a click when it lands on a burned / corroded spot, but your car starts when it lands on a spot that's still clean & smooth.

Dosnt keep a charge


Its ether the battery or the alternator. The best way to check it is with a load tester. To check it hook the tester to your battery with your car running, red to positive (+) black to negative (-) if the alt. Is good it should read around 13.6 volts to check your battery shut off your car and toggle the load test switch hold for a 10caribbean count the meter on the tester will tell you if its good. If you don't have one or can't get one most parts stores. Will do it for free. If both check out good you have a dead short somewhere. In that case you just have to track it down. But start with battery or alt.

92 sable wont hold charge good batery new alternator what could be the problem


first you need to check your unit maybe it is grounded,,how to know if your unit is grounded? using tester get your tester in x1 mode, test the tip of battery terminal positive to positive negative to negative, automatically the tester make a deflection.after that switch it .. positive battery terminal to negative wich is the color black wire of the tester,if theres a deflection again ,,,, your unit is grounded

Truck just clicks down at starter...have had no sign of starter slipping and lights still on so dont believ its battery


Hi there,

That clicking noise is your starter solenoid. There can be different causes, the most common is the battery. I will explain what is happening.

Your starter needs a lot of power to turn your engine. That much power would melt your ignition switch in no time if it passed directly through it. So what happens instead is your ignition switch actuates another electric switch called a solenoid. The solenoid is a really HEAVY DUTY switch.

Inside it are two copper contacts that look like the head of a bolt only rounded. The battery is attached to one, the starter to the other. Hovering above them on a spring is a copper clad disk attached to an iron core. The iron core is inside an electro-magnet.

When you turn your key (in a perfect world), an electromagnet is activated that yanks the disk towards the contacts (Making a single decisive healthy CLICK). When they connect, the circuit is closed and the starter turns over. OK.

When things go wrong:

Low Battery:
  • The solenoid requires power to actuate.
  • The starter takes a lot more power to turn the engine.
  • When the battery is low, there isn't enough power to do both.
  • You turn the key, solenoid engages (CLICK)
  • Power goes to the starter
  • The starter tries to turn the engine
  • The draw from the starter drops the available power below the minimum needed to keep the solenoid engaged.
  • The solenoid disengages
  • The starter is no longer drawing power
  • The additional power allows the solenoid to re-engage (Click)
  • Repeat the process for as long as you have the key turned. (CLICKCLICKCLICKCLICK)
That's where those clicks are coming from and why.

The remedy:
Short term - Jump start
Long term - Charge or replace battery.

There can also be a problem with the solenoid. Specifically, with that copper clad disk I mentioned earlier.

When that many amps are drawn from a battery there is heat and sparking which erode the copper plating. There comes a point where ther disk can no longer 'Complete the circuit'. It then needs replacement.

How to tell the difference?

If it's the battery, a jump start will work.

If it's the solenoid, a jump start will have no effect.

I wanted to explain what was happening rather than just saying 'dead battery, replace it'. That way you can judge for yourself whats going on.

I hope you can find the time to rate this response.

Best regards
Mike

Starting solenoid clicks...sometimes starts and sometimes starter just clicks?


Hey there sluggo,

I'll assume the battery is fully charged and get right to the solenoid.

The solenoid is a really HEAVY DUTY switch. A lot of Amps need to pass through it for you starter to turn your engine.

Inside it are two copper contacts that look like the head of a bolt only rounded. The battery is attached to one, the starter to the other. Hovering above them on a spring is a copper clad disk.

When you turn your key (in a perfect world), an electromagnet is activated that yanks the disk towards the contacts. When they connect, the circuit is closed and the starter turns over. OK.

Well, as you can imagine, each time the disk makes contact, there is a bit of sparkage which can erode the copper plate on the disc. The reason it IS a disc is that it rotates a bit each time it connects. This way the contact surface lasts much longer.

After a while though, you do start to hit bad areas. Thats when it's time to replace it.

Again, that is all dependent on the battery being fully charged.

I wanted to explain what was happening rather than just saying 'replace it'

Best regards to you
Mike

Battery won't stay charged but the altenator reads good


have the battery and charging system load tested with an AVR load tester, battery could be sulfated internally, etc. if it is good have a parasitic draw test done. hope this will help
