You are watching: Hooked battery up backwards now car wont start
I mounted my new battery in the dark and connected the positive cable to the an adverse post and the negative cable to the positive post. Currently that the battery is installed correctly, the starter transforms over yet the engine will certainly not start, and the radio will certainly not revolve on. What the hell did ns do?
If friend didnt develop it, the AIN"T YOURS!!!!89" Notch, XE3 340 HP Ford Crate Motor, V2 SQ Trim Vortech, MSD Billit dist and also 6al box and also msd blaster tfi coil, 42 lb inj, edelbrock intake, 85 mm Abaco mass air, 70 mm tb, 3.73 rear w/ spool and also moser 31 spline axels.
All fuses under the dash room fine. The just fuse I uncovered under the hood is fine also (it to be for the NX system). I have actually a 1987 GT w/ MSD 6BTM, MSD Billet distributor, Accel coil, and also Moroso rear-mounted battery box. Are there any kind of fuses in mine ignition system?
take a check light and also trace the power....start with the coil...was there a fuse in your battery relocation kit?

One fuse went out on the battery box, and also has been replaced. Internal lights and also the starter work, but for some reason the stereotype is out and also the ignition seems dead. Ns don"t know why the two would it is in related.
I did the very same thing on mine motorcycle and also it to be a fuse. I"m certain thats what that is v yours....you just need to hunt because that it. Check and also see if you space getting any kind of spark at the spark plugs. I"m no positive, however isn"t there a fuse on her msd? If no you can have fried that. But then again that wouldn"t cause your radio to not work. Make certain you inspect the fuses with a multimeter or fuse checker....sometimes they may look ok, yet they aren"t. After friend check every one of that, then you have to examine wires to make sure you didn"t burn one up. Good luck.

Disconnect and also take the MSD out of the loop. Critical time "a friend" assisted me placed a battery in, the fried the MSD, Monster tach, and Aeromotive pump controller. The friend price me around $750

There"s power going right into the MSD, yet not out (a test light come the coil shows no juice). Ns think i fried the MSD box, and also will be buying a 6AL tommorrow.
Check to make certain the alternator works as soon as you acquire it running, girlfriend may have fried the neg diodes in it together well. Carry out NOT eliminate the battery cables to do this, you will certainly fry the diodes if friend do, simply inspect for a voltage rise once running.
Sounds choose you"ve tracked it under to the MSD box. ~ above a side note, space you getting fuel? examine to view if her fuel pump is priming the system. Maybe you fried part wiring come the fuel pump.

Poosible, yet like ns said as soon as my "friend" helped me it gained the MSD and I had a 3G alt on it, and also it DID pop the large inline fuse i had. Definitely check the alt circuit. The reason why it acquired my pump controller was that I had it wired directly thru a 12v batt power circulation block.

dose the car turn over? if no i gambling it is the Starter relay situated on the driver side next to the battery . Friend mighta fried that ..
There room fusible web links coming turn off the starter selonoid..orange and also yellow wires v plastic nubs on them saying fusible link.
definitally inspect your fusible links. Her radio have to work, is that an aftermarket radio? If for this reason it will certainly probabbly have actually a seperate fuse in the ago of the radio.

If it"s no the MSD (after reinstalling a brand-new one), it"s feasible you could have blown out the EEC...
The engine does turn over, so the starter is fine. I hear the fuel pump rotate on too, i beg your pardon is regulated by the EEC, for this reason the EEC appears to be okay. I"m expecting the alternator to it is in fried, though.

I understand what friend did. Ns did the exact same thing 1 mainly ago, inm the dark not discovering what ns doing. Heres the deal, for her radio, over there is a fuse that need to be linked to the ago of it that most likely blew, as mine did. Friend most likely fried yoour starter relay beside your bat. Through the coil. Examine down in there, space some wires, inspect to guarantee they space all there. Your auto will crank ovr and shot to start yet it will not start due to the fact that you fried and burnt up among these wires. This is waht ns did and also I had to go ago inand replace the wires. Mine to be green, yet I think I had to replace it before. Im pretty certain its the starter relay the you burned up, simply look down listed below the coil for numerous wires and also feel them, you def. Charred one of them up and your walk to need to splice ina new piece that wire. Ypur automobile should begin perfect then.
