Q: Wont start, new battery, new alternator

asked by on

i have an 2001 for explorer with the v6 SOHC, drove it from colorado to minnesota and had no issues, but shortly after getting back i started having issues with it, brought it to a local mechanic and found out the fuel pump and fuel filter needed to be replaced, so got it done. 2 days later started have issues again, i put a fully charged brand new battery with 800 CA in it and dont even get a crank, just clicking, but if i jump it with cables it will start and run just fine. So i let it get to running temp. and then turn it off, go to try and start it again and the battery is completely dead. Im no mechanic but i have worked on cars for many years on my own and never ran into this issue, if you could point me in the right direction i would really appreciate it. thank you for your time. Lenny

From what you’ve described, you may have a bad battery cable.The clamp and cable may not be making good connection inside of the clamp where the cable goes into it.

You can test this with a voltmeter by measuring the voltage drop in the cables and grounds on the engine. A bad cable will cause the problem you’re having and a cable end or cable replacement will fix the problem in most cases.
