When I connect the battery the blinkers come on constantly glowing, nothing else works, check the fuses, the alternator fuse is blown, replace that, connect the battery fuse blows again. 2007 solara.


Bad alternator or short in alternator wiring. You much need a wiring diagram. Is that the car? Was in an accident? You may have pinched wiring or a wire shorted to ground. Try new fuse with alternator disconnected, then with key on, connect alternator-watch for sparks, or clicks, -you might want to have the alternator tested, just to be sure. You have to start somewhere...
Maybe a wiring short in the blinker system? Or is the fuse blowing an alternator fuse?

Why my 80 amp fuse blows?


take the alternator in for a bench test as the dead short is in that unit
could be blown diode block, shorted windings , shorted brush insulators , shorted insulator around the bolt that the wire is attached to
once the alternator problem is fixed the rest of the symptoms should fix them selves

Looking for the fuse that works with alternator.


no standard fuse in a fuse panel some vehicles have a master fuse/link that attaches inline if looking to pull fuse follow battery positive to where it links up with alternator some are by battery some by radiator but if its a fusible link not going to be able to pull it ---and as to a regular fuse their is none and some vehicles dont have any short in alternator usually means no out put if short in wiring than would have a constant drain on battery --their is no fuse that would stop that if short in wiring test the lines and replace the wires their is usually about 10 ft of wiring --if alternator pull connector from it

My 1987 Camry Alt Fuse Keeps Blowing. Brand New Alternator Brand New Battery . As Soon As I Change The 80 amp Fusible Link And Reconnect The Battery It Blows Immediately


I suggest to check if you have oil leaking onto your alternator or did you recently replace the alternator? Keep in mind that the voltage regulator is built into the alternator on vehicles and I have seen oil leaks internally short the alternator or poor quality aftermarket parts.

Also check ground and wires broke or in short.

Alternator not charging


Possible short to the starter. I had a similar problem with my '91 mercury capri. I replaced the alternator and battery but the alternator would not charge the battery. My local mechanic spent hours tracking it down, but finally found the problem. Have not had a problem since. Good luck

The alternator getting hot & the bus not start


hi, this is one of these faults that the alternator, is INTERNALLY SHORTED or the POSITIVE FEED FROM STARTER MOTOR to the ALTERNATOR to the car (LARGE CABLE). there is a way to test this. take the battery (NEGATIVE LEAD) (as not to short-out the battery cable) off and TAKE OFF the (BOLTED TERMINAL and the second cable) of the SMALLER ALTERNATOR CABLE replace the LARGER CABLE to the (ALTERNATOR and BOLT this ON to determin if the alternator is shorted OR it is the cable from the ALTERNATOR to the CAR FUSEBOX. ( you may need to read this again, not easy).if when the battery is reconnected to the alternator it cools down ALTERNATOR O. K.(then the LARGE CABLE that SUPPLIES the car is SHORTED).

THIS CABLE CONNECTS FROM THE BACK OF THE ALTERNATOR (BOLTED TERMINAL) AND GO TO THE FUSEBOX

because the battery is connected to the alternator and the alternator is conected to the fusebox. (the battery to alternator is part of the CHARGING CIRCUIT and the alternator regulator is the other part, only when engine running 1500 rev min. gerry

I was changing the alternator belt, and shorted the alternator. Now none of the power on the car will come on no headlights nothing. I changed the alt fusible link still nothing. Any clue what else could...


YOU SHORTED OUT VOLTAGE REGULATOR.SOME ALTERNATORS YOU CAN REPLACE VOLTAGE REGULATOR WITHOUT REPLACING ALTERNATOR.OR YOU HAVE TO REPLACE WHOLE ALTERNATOR.ALSO CHECK IGNITION SWITCH FUSE AND ALTERNATOR FUSE.
