In a hurry and cuz I can’t hardly see at night, I connect the terminals the opposite way, the positive where it’s supposed to be negative and I saw a small spark.
Umm, will it ruin my electrical system/car whatsoever?
Did you put it back the right way and see if you got anything? Best way is to hook up a battery tester or a voltmeter to see if the battery is damaged.
i did this when i first got my intake… this was years ago… and i didtn kno **** baout my car… well… we were working at nite, and when we installed the battery back in, we put it in worng. this is what happend… none of my electrical worked. … and iw as freakin out… my neighbor checked all my fuses, and it happend to be one of those big blocky ones that is under the hood… it is ur main fuse box, and the fuse is the one that has all the power of the car goin through it. look at that… the battery is fine, i did this three years ago, and i am still using the same battery. if that fuse is still good, ntohing is wrong with ur car, dont trip… matt
