Okay tell me if i have missed something

94 TA runs fine, as soon as I shut it off it won't start after that. Put the jumpers to it and it starts right up. Volt guage in dash is showing it is charging too much sometimes. Had the battery and alternator checked and they said the battery was low but not bad, and the alternator was fine. Checked my ground and power cables and didn't find anything checked connections and cleaned and reinstalled them but nothing has changed. Is there anything else I can do before having to start chasing circuits, also is there anyway to test the voltage regulator and see if it is charging too much cause this is the second battery in two months and I don't want to exchange it for another just to have to be ruined again.

 

Your problem sounds like your starter is on the way out.

Check the voltage across the battery before you start, during cranking and after it starts.

Before it cranks, it should be sitting at about 12.6 volts.

During cranking it should not drop below 11 volts.

After it starts, it should be around 14 volts.

As a starter gets old, internall windings begin to short together causing it to draw more and more current. It sounds like your starter is drawing too much current and eventually gets the battery too low to crank it over until it's jumped.

This is all assuming that you checked and or cleaned ALL of the connections from the battery to the engine and in between.
