Polarity was reversed when jump starting vehicle installed new battery & no power to anything mechanic said fuse got blown.What fuse,where it is located & cost of it.

Hard to say without make, year, and model-but check all fuses in the power distribution box under the hood- ignition, alternator fuse, etc.-all of them, the small ones and the maxi-fuses. All fuses are pretty cheap. If you still have nothing, you may need a wiring diagram to check for fusible links that would be power distributors right off or near the battery. Fusible links work much like a fuse, and most have been replaced by maxi-fuses, but many vehicles have both. If there is a designated main fuse, it should be in the distribution block or box under the hood.

Reversed polarity on jump start. now wont go into gear or hold charge

OLder cars YEs you can jump it without a battery. But in newer cars that use computers and advanced Eltronic ignition/timing/ful injection you have to have power to the cars computer. without a good battery the car will not run.---------------------------------------------------------------------------------

Car battery installed backwards - reversed polarity. blew whole bunch of fuses. now remote starter not working nor the door lock. viper 771X alarms works just fine. any idea if there is a fuse in the...

I'm sorry to hear that that happened to you. I think that when opposite polarity blows a bunch of fuses, and smoke pours out of the dash, it's a worst case scenario.

I've seen what electrical fires can do to wiring, and it's not pretty.

I'm not sure about the Chrysler 300 from 2005, but commented anyway.

Good luck on repairing this problem. You may need the assistance of an auto electric shop.

sorry to say , get a voltmeter and go through the wiring starting at the fuse box and follow on from there, that includes the ground circuits, its time consuming but revesing polarity can cause untold damage

Reversed polarity on 2000 mazda millenuim, now my car wont start

if you are lucky, only the fusible link(in the fusebox in the engine bay) is blown. if you are not lucky, a whole lot of modules are blown, and this is really expensive.

Ignition problem, won't start

Your battery may have reversed polarity. The same thing happened to me in my '94 GMC Sonoma. One crank and then nothing except my (+) battery terminal got so hot it almost caught fire. There is no way to test for reversed polarity and even on Autozone's test machine, they swore up and down my battery was good. They refused to warranty it, so I bought another battery. Once installed, my truck ran like a dream again. I took my battery to a different autozone and they warrantied it.
