Question
hi I have a Mitsubishi Magna TR Executive 1992 Auto 2.6l 4 cylinder and I want to auto jump start it but I'm not sure if it has a Negative or Positive grounded system.lm trying to use a 400amp auto jump starter.

Answer
Ben,
The Magna was not a vehicle sold in the States, so I can't give a 100% guarantee on my answer.  But the Magna is a sister car to the Diamante model which is sold in the US.  On the Diamante, it has a negative ground.  If you want to be sure, you should contact the service department at your nearest Mitsubishi dealership.
Good luck!
