1987 camry blows 30 amp fusible link when ign turned to on positi
30 amp located at positive lead at battery keeps blowing car will not start, problem started shortly after head gasket job done wires look good no breaks in wire or rub through but cannot keep fuse from blowing
Re: 1987 camry blows 30 amp fusible link when ign turned...
Something is drawing too much power and you will have to find out which it is. When the head job was done they may have gotten a wire pinched in the block or some thing. You would have to be quite mknowledgable in vehicle electronics to find it. I would suggest that you take it back to the shop or guy that done the head job for you to correct.

If the truck had a three terminal one on it then you would not use the (I) terminal, nor would it cause you to keep blowing your fusible link. It would cause a hard start cold because all the (I) terminal does is feed 12v directly to the coil on cranking. You have a short in the circuit that is on that fusible link. You need to get a wiring diagram and see what that circuit feeds. If the fuel pump isn't running than disconnect that circuit and see if it keeps the link from blowing. You may have to get a circuit breaker to install temporarily it to help find short. I have used a breaker and have gone directly to the fuse box and feed there to help isolate which circuit it is in. Good luck.
well lets try a couple things to see if we can solve your issue. first off, do not start the car but turn the key to the ign. does the fuse blow? if no step on the brake. did the fuse blow? if no then put the gearshift from park to drive. did the fuse blow? did it blow? last of all look and see if you can tell me what the fuse that blows is in what circuit. Try those steps let me know what you come up with and ill be able to give you better info. thanx, rick.
I am assuming you are talking about the circuit that powers the key switch. I'm showing a fuseable link to the starter relay instead of a fuse. If it is the circuit that powers the switch, I would disconnect the switch and see if the fuse blows as each circuit is powered one at a time using a jumper wire. You can get 30amp circuit breakers that plug into the fuse slot to use while you are testing circuits. You may need a repair book or shop manual to find out what is powered by that fuse since it is most everything on the car.
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.
I would start at the starter, it could have a short but it's only apparent when the engine gets it hot. you can try to pull the fuses to other things and see if the problems stop. this will at least give you an idea of where to look. also check fusible links and look for wire corrossion
It sounds like you have a short in some wiresets. Check the wires directly connected to the ignition. If this persists, without any problems with wires, I suggest checking the amperage and voltage on your battery to make sure they are at operational levels. Anything over 14.8 volts and you start to fry electrical components and... blow fuses.
On the 92 S-10 it sounds like the actuator rod that is connected to the ign switch on the bottom of the column could be possibly bent or the rack and pinion could be broken inside the column. The ign switch my be out of adjustment. You can try to adjust the ign switch on the bottom of the column yourself. If that does not work,my suggestion is if you are a novice is to take your vehicle to a mechanic to get the steering column fixed.
On the 91 blazer there are 2 fusible links that the battery cable connects to on the starter. Jack the vehicle up & use jack stands under the vehicle. With a test light check to see if there is power to the starter solenoid where the battery cable is hooked to. If there is power find the 2 wires that are on the same post that the battery cable is hooked to on the starter solenoid, they will have a white piece of round plastic (about a inch long) with a wire going into and out of it. This is the fusible link. Probe the wire before and after the round plastic. If there is power on one side and not the other side,you will need to replace the fusible link. You can use a inline fuse holder with a 25 to 30 amp fuse to replace the the fusible link.The fusible links supply power to the vehicle inside for the lights, radio, wipers,ign switch, etc.
