93 honda accord.When you try and start it the negative battery terminal sparks some and then lose all electrical power

Give it a few mins and power is back til you try and start it then same ****… Wtf is the problem it's done it with both a new battery and old one.

Hi well the numbly who fitted it did a poor job on the connection so it needs tightening up.

How many times are you going to ask this dumb *** question before you go and replace the bad clamp on the negative cable jojo?!
