What would make a qx4 positive terminal spark
3 Replies
It the terminal is not tight it could cause a spark to jump. Alex
Some spark is normal right when you connect the jumper. Really a loose connection is the main reason for sparks.
Reversed polarity!
Possibly a dead short to ground .. Something drawing an extreme amount of ‘current’ .. Headlights on?
WhAt other causes are there
connecting the jumper cables backwards will really cause a spark,lots of em and could possibly blow the battery up! I have seen that,and it ain't pretty.
