Ok... so like everybody suggested I went down to Canadian Tire and I picked up a multimeter and in addition I bought a 4ga pre-crimped wire from there too.

Car was running perfect at this point.

I get home and I am going to install the 4ga wire to get a better ground at the chassis. I first take off the positive terminal off the battery. I then take off the negative terminal and attached the crimped 4ga wire to it. The other end of the 4ga wire was bolted down with a wingnut and a washer to a polished/sanded piece of chassis. I then go to put the positive terminal back on. I just touch it and there is a spark, so I quickly pull it off. I see some wires on the other side of the engine that smoked up.

Anyhow I took everything back off and put it to how it was before. The car does not start... it just keeps cranking over. The engine and oil lights are on even when the key is not in the ignition. The battery is still OK because I tested it with multimeter I bought (how ironic) and it registers 11.8V. I did not confuse the terminals when I was wiring anything either. I checked all the fuses in the engine and the cabin and they are all ok too.

If you've read my other thread about the ground... yea I agree I ****ed up before but the car still worked perfectly after that. So please don't bring that into this thread.

Does anybody have any suggestions? I could even take some pics of the two small wires on the other side of the engine which were smoking and other things that could help clarify things.

NOTE:
Something interesting I noticed is that I had to reverse the polarity of the multimeter to get a positive reading on the voltage of the battery that I currently have in the car (Eliminator). In my basement I have an old battery from the Mazda and it registers 11V when you touch the positive to positive and negative to negative. Dunno what the deal is with that I know which terminal is labelled positive and which one is labelled negative so I didn't mix anything like that up.

Something similar to this happened to a friend of mine when he tried to make a distribution block outta homemade crap. anyways most of you know where this is headed and he didnt put a fuse in the power wire and when he tried starting the car it fried his alternator wiring harness it was very smoky i dont think it was his best moment. Umm where abouts are the wires dow you know whether they connect to a sensor or to the comp or what mayb e a few more details may help me help you [img]graemlins/beer.gif[/img]

If indeed the posts were reversed on your battery from the maufacturer your car would have never started from the beginning. I think pics of the wires and the engine bay may help sort this little dilemma out [img]graemlins/thumb.gif[/img]

Ok about the battery... I had the probes plugged in wrong into the multimeter and I was testing the wrong terminals on the battery in my house. That's why it registered the proper voltage. The car was registering the wrong voltage when I had this same setup. Anyhow that is beside the point now.

This wire was smoking and that piece that is sticking out got disconnected from that harness that you see there when it burned through. I put that wire back in temporarily and tried to crank the car up but it wouldn't fire. Something is definately screwed in the electrical system.

Here are some pics:



And to the people that have done that before... did the car still fire up after?

wow...a mustang with a mazda motor!!!

I would THINK from what youve said, you got the battery terminals backwards. This would also explain your amp not working.

I'm thinking if you connected your + battery terminal to your chassy maybe you blew your fusable links and that's why your car isn't starting

Dude...............seriously...........I'm all for people trying it themselves but.............

You need to get a professional to look at the car.............stop now while the car is intact.....................

OK... I fixed it now... I reconnected the wires with a lot of electrical tape. The car is running properly now.

Immediately after the car was ****ed up I took out all the wiring.

Once again after I fixed this wire, I tried to put the chassis ground on. This time it went on proper with no sparking.

I think what I did before is I had the power on the negative battery and I was putting the chassis ground on the positive. That would also explain why my amp didn't work when I was grounding it.

Like I said it was like 2AM yesterday when I was wiring it up so I wansn't thinking straight.


this is what I think happened.

I've done a few other stereo installs and they went without hitch... plus I'm not willing to pay some guy $50 to plug a couple harnesses together and crimp some wires. Then maybe another 100+ to run some wires under the carpet. I can do that **** myself.
