Question about 1995 Mazda Protege

1 Answer

The electrical system fails while driving

The car run fine however when replacing the battery it was put in reverse polarity and blew main fuse. We replaced this and it seemed fine for a few days. Today the car stopped running while driving and when I pushed down on the individual fuses I got power temporarily, but not long enough to move car. I'm not sure where to start looking next. I am pretty sure its around the fuse box and since the battery had been installed backwards, is there any place I can check for damage first to avoid Easter egging the electrical systems?

I would say you have toasted your main fuse board and the only true fix is to replace it GOOD LUCK

Jump start reversed polarity now nothing

That sort of thing can badly damage management system, relays, melts connection, fuses. There is a fuse for the computer, check your manual. But get it diagnosed.

Try resetting the CPU program as it may be corrupted from reverse polarity. Have the ECM checked out as reversed polarity tends to damage them internally.

Replaced mega fuse now wont start

Putting reverse polarity to a battery will do more damage then blowing a fuse. Chances are you could have taken out the ECM and possibly the TCM

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 Fusible links work much like a fuse, and most have been replaced by maxi-fuses, but many vehicles have both.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.

I put the battery backward on my honda prelude while it was running and now it wont start can u tell me what wrong

The reverse polarity should have blown at least 1 fuse to prevent further electrical problems, I would start by looking there, replacing blown fuses and then trying to restart.

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.

Hooked up the battery reversed polarity. Blew the fusible link but replaced it. Now the car will crank but not start.

start checking fuses hopefully its just another blown fuse if your lucky

but if all the fuses are good, you probably fried something like the computer or ignition module and probably the radio

hopefully its something simple and cheep but don't be surprised if you have to shell out some cash to replace the computer

If the battery was improperly polarized (polarity reversed) you may have a lot of damage.
The main fuse isn't the last one you need to replace.
To measure them, you should have some kind of multimeter and it would help for the other tests as well.
(They can be had for <$20 US at electronics stores or, for a few bucks more, auto parts stores.
Any of them are accurate enough for home use.)

If that has happened, the alternator could well be fried; the output diodes are oriented so that they would have looked a lot like a piece of wire to the battery and while they are rated at high amperage (100 amps or so) the battery could have supplied twice that and caused them to fail.

You need to measure the terminal voltage across the battery.
Normal for a charged battery is 12.6 volts, charging at an idle 13-13.5 volts and maximum at any RPMs, ~14.3.

If the main fuse was blown, I suspect the battery was installed incorrectly.
