[ROVERNET - UK] Polarize?

[T. Clemen]

Hi all
I was installing my new grose jets and ran into a problem trying to start my 
car.  I turn the key and get a hum from the starter.  I may have 
accidentally touched poles tightening my battery cables down.  For the life 
of me I can not remember the correct way to re-polarize my system, if indeed 
this is the problem.

Please let me know, the battery is charging now and I can't wait to see if 
these grose jets solve my fuel leak issue.

Thanks

Tom C.
