Question about Volkswagen Jetta
The battery on my 2002 Jetta needed charging, so I attached a battery charger to the post but connected to the wrong terminals. The charger was not connected to an AC outlet but there were sparks and now the car will not start. What do I check to resolve this problem. does the positive lead from the battery have a fusible link? The engine will turn over but the car will not start. any assistance will be appreciated
If the charger is connected the wrong way round then lots of current will flow and any fuse in the circuit will probably blow.
If the battery charger has a fuse it is likely to have blown if there was a spark. It would then not be charging your battery. A low battery may not quite start the car.
Also If you did not connect directly across the battery there could have been a fuse in the car that the current had to flow through that may have blown. There are quite often a few larger fuses or a fusible link near the battery. They are not always easy to find so look in a service manual or ring a VW workshop and ask where the main fuses are.
It's a bit unlikely to have done any major damage I think.

so you reversed the connections and you think you nuked something? Right?
Check all fuses and relays. Replace any fuses that are blown and all relays that look scorched/burnt.
If that doesn't work, take to dealer to make sure the computer and advanced control electronics didn't get fried.

clean battery terminals ,bring battery to be tested after charging, after reinstalling battery run car and test alternator output it should be a minimum of 13-14volts if it is under 13 replace alternator , use a voltmeter set on 12 volt 10 amp dc to check the wire to check is located on the back of the alternator covered with a rubber grommet of course hold negative wirw on volt meter to ground and touch red wire to big terminal on back of alternator while car is running should have 14 volts or at least 13 volts

There's a relay on the brake pedal arm that actuates when you press the brake pedal. This releases the lock on the shifter, so you can shift out of Park. VW's are notorious for having issues with this relay. Stick your head down by the brake pedal and you'll see where the pedal arm hits the relay. It's more than likely stuck, and may not need to be replaced. I'm guess you probably have no brake lights either...
