Won't start after jump

[jaschlum]

Hey guys need your help again. I started a car with my 92 explorer, it was a difficult jump but got it to work. Now my explorer won't start up. It doesn't even turn over and won't start with a jump either. What do I do? Connections are all good. Please help.

You may have ruined your own battery.

Double check your main fuses and starter solenoid.

Main fuses all looked good. How I test the solenoid?

You got a multimeter? Measure the batt. voltage. A good battery should have 13.8-14.4V. Try to crank the engine. How far down does the voltage go?

A good solenoid should make a clicking noise. If your battery is ok, and you don't get crank, give the solenoid a light knock with a hammer while trying to crank.
