I had a burned aircon relay (stock-Jideco brand) for a Mazda power van. I hav change it to Bosch Brand. Both relays have 5 probes or connector. I think i have connected it right because it had a schematic diagram. But whenever i turn the aircon on my fuse burns. What do you think is the problem?

Re: vehicle aircon wiring
The problem is probably the same thing that caused the relay to burn out in the first place, try un plugging the aircon unit, control section and anything else you can find that is related. plug them back in one by one and see which one kills your fuse......

You look it up in factory service info , look at a wiring diagram , fuse box diagram etc.... This vehicle also has an inertia fuel shut off switch . You can view all this at http://www.bbbind.com/free_tsb.html
Also know that the PCM - engine computer turns on the fuel pump relay . If there is no crankshaft position sensor (RPM signal ) to the PCM ,the PCM will not turn on the fuel pump relay . Relay #5 is fuel pump relay . Do you know how to test electrical circuits ? Use a Volt meter ? Or are you just going to replace the relay and hope that's the problem .
Here's the alternator test before you spend money: Start the car, then disconnect the positive batter cable from the battery. If it stays on, the alternator is fine. check your relays under the hood, located in the fuse box. Tap each one, if you get a response when you tap or wiggle a relay, change it
I do know that there is a main relay in the car that plays an important role in the car starting/running. I have changed many distributors, thinking that they were deffective. When turns out that relay was Intermittently working causing the car to run one day and not the Next. I do know that heat is a factor because if my car windows were left up and it was burning hot inside the car it wouldn't start, but once it cooled down it would start. Sounds like yours is just completely dead. It costs like $80.00 for the relay but and acura/honda repair shop should have them stocked.... Notoriously known for similar issues your having due to deffective MAIN RELAY
where did u install the FOG LAMP relay and what connection of power( + ) did u connected it to?
If the Lamp u have use is more 100 watts, u have to get the power directly to the battery and make power line independent from other accessories!
Let me explain real quick the fuel pump circuit, when you crank to start that is a straight circuit to the pump via a fuse in most cases, when the engine starts and you release the key the fuel pump relay is energized and keeps the fuel pump running, it sounds like the fuel pump run relay may be the problem with your car, replace it or bypass it to test, if you don't understand how a bosch relay is wired don't jump it yourself, you can burn up the wiring.
sounds like you have a fuel pump issue. first check the fuel pump relay. it's in the junction box under the hood. replace the fuel pump relay with the a/c clutch relay or heater relay and try starting the vehicle if the vehicle starts it was the relay if it doesn't check to see if there is power going to the fuel pump if there is your fuel pump needs replacing if there isn't then check the wire harness for a break in the wire. please rate
i have to say it its a bad relay for the windows somtimes they come with more than one and the other will be in engine compartment or under dash
but over all i believe it to be relay cause relays can have a good check and then fault once everythings back together i would just go and buy the relay package for your vehicle so that all relays have a new set you might run into same problem down the rode with other relays might as well replace all
relays need to maintained or be brand new after 100,000 miles every 100,000 miles this keeps vehicle in running condition
there is a way to check power using a fused guaged wire fined good power source and touch the switches power pins this should run the window motors giving them power once you by pass the actual wireing with a fused guaged wire you will know its a bad relay cause the wireing has to go threw the relay first
