I was driving one day and my kill switch was rattling loose so i grabbed it and accidentally hit it and turned it right back on but the car died still and never started up again and i had to tow it home. i took the whole kill switch out and re-connected the original wires. i fixed a blown fuse and tried it again and it didnt start and now my batteries dead and my charger isnt working. Im mainly wondering if i need a new battery or just a charge or if thats even the problem. the cars been sitting for 2 and half months. thanks to anybody who reads and helps

You won't be able to try anything until you charge the battery.

And which fuse was it that blew?

tessaiga91

i just threw the battery on the charger so ill let you guys know what happens but thanks.

i dont have the fuse box cover so i dont know which one it was but it was a blue 15

It's likely the Engine fuse, which powers various items including the Circuit Opening relay which is the relay that the fuel cut switch would be routed to.

check the EGI fuse too.,engine bay.

zenbeast

Then after you check the fuses you need 2 things..

Gas and spark.

Check your primary coil. for spark.

tessaiga91

How do you check the primary coil for spark?

tessaiga91

After i do this and say its ready to start, will it need a prime of some sort or should it fire right up after 3 months of sitting?

Pull one of the plug wires off of the leading coil and place it oh so close to the coil bore but leave a fraction of an inch between the coil bore and the plug wire and then turn the car over and you should see some spark. Also make sure both of the EGI fuses in the engine fuse box are good as well as previously mentioned and the engine fuse also needs to be in working order.

And you might want to add something to the gas to revive it.

Here is a you tube video that might help with the idea.. TEST for spark..

oh and here is a reference for your fuse box...

I had a similar issue with my 86 n/a and it ended up being the two thick wires under the steering column that connected to the ignition switch. One was melted and shorting out. I had power to everything else but was unable to start the car.

i charged the battery and jumped it with my mnoms mini suv and it started right up after almost 4 months of sitting. i let it run for a little and then cut it and tried starting again and nothing happened so im guessing thats the battery?

zenbeast

I think you can jump the car started and then .. if im right ... someone can interject here.. rx7 might not work like this..
But while the car is started take the negative terminal off.. if the car keeps running then your alternator is working.. if not then maybe it is your alternator not charging the battery right..
But that could be a connection with the alternator..

So then you would check your alternator connections..

you can take your battery to auto zone and have it checked if you want to take it out..

tessaiga91

good **** man i didnt even think about that, thanks for all the help

It is not a good "idear" to remove the battery cable while the car is running. The alternator has a Black cable bolted to it and this is the output wire. While the car is idling you take a voltage reading from this cable. Voltage should be in the 14 to 14.4 volt range.

... So here is info..

with what do you take a voltage reading with? Thanks for that link bro, and the help regardless

A multimeter set to dc volts?

tessaiga91

alright thanks

skkitz

you can also use any aftermarket voltage gauge(done it multiple times)

tessaiga91

how much do those cost and do i get that at autozone or any other store like that?

skkitz

you can get a aftermarket voltage gauge from autozone for 20 bux
