    Wiring help needed

    in Ignition and Electrical

    Posted

    I have just finished installing a GM 3 wire alternator in my 72 Z. I have gone through the write up on the forums on how to do it.

     

    I now need to know what to do with the wires that go to the voltage regulator. I did see some diagrams showing what to do with them on a 76 and newer. Please help. Thanks in advance.

    Thanks. Got the fuel filter all taken care of. The alternator hook up is correct.

     

    I decided to unplug the voltage regulator to see if the voltage would still increase and over charge the battery. The voltage stayed at 12.4 or so. I let the car running for a while and it did not decrease or increase at all. I drove it around the block and checked again. Still the same. I checked the wires and they were not hot and the one off the started was not smoking. Not really sure what is going on here.

    I had to put the point pretty close together to get it to fire. I believe that it is misfiring because there is a slight stumbling.

     

    I am still working on my voltage issue. I replaced the V.R. but my voltage is still increasing above 16 volts. My wires are heating up and the white power wire off the starter smokes after a minute or two.

    I got the car started. Thanks to everyone. Have a question. Once I got it started, I noticed the white wire on the stater was smoking. It was the positive 8 gauge wire right where the battery is attached to the starter. Any ideas as to what is happening? I will be changing the voltage regulator once it arrives. Will that solve the problem? Thanks.

    Just got home. I have doulbe check all the plug wires and connections already and the firing order. The plugs came gapped at .034 thousandths, I checked before installing. I will work on it now and see what happens.

     

    Lastly, I noticed that the owner before me have removed the fuel filter. I have one to put in but I need to know which line is which. The filter is the "L" shaped one made of plastic. Please let me know how is it hooked up. Thanks.

    I used the Chiltons manual for setting the point gap. It said to set it at .4 to .5 mm at the highest point. Would that be about the same as you stayed? I will double check that. I just bought all the stuff for a tune up so I really do not want to buy a new setup. I will have someone crank it while I check the timing later. Thanks Greg.

    Thanks for the response. I have determined that the voltage regulator is faulty. It continuesly charges the battery. I will be replacing it.

     

    I have just finished a complete tune up today. I looked up the timing and it should be at 0. Anyways, changed points, plugs, wires, air filter, and cleaned up the fuse box. NOW THE CAR WON"T START! What is going on? Thanks in advance.

    Well I replaced all the fuses that I cound from under the console. There are a few that I cannot since I don't know what amp they are. Anyone have a picture of the fuse box cover that show what the fuses are? I did an oil change and put in all new battery and groud cables under the hood. I can get the car started but it is not running well. I will be changeing plugs, wires, and the distributor/rotor as well. I will also buy a timing light to check the timing on Sunday. Where should the stock timing be?

     

    Well here is the other problem. I got the car started but once it is running, you can not shut it off. I can pull the key out but the car keeps running. The previous owner had told me about this but I have no idea how to fix it. Lastly, there is one wire in the center console that is getting really hot. Not sure what it is to. It is white with a red strip. I think it screws right into the fuse box. Any reason why it is getting so hot? Thanks again.

    Well, if any one has any ideas as to what happened please let me know. I was in 5th diving about 55 mph. It just suddenly lost all power and started to coast. I pulled over. Tried to start it up but it will only crank. Wil not start. No fluids were leaking from the car, no smoke, or funny smells other than a bit of the fuel smell. I also noticed the the battery was very hot and looked as if the fluid was coming out of it. The battery is a new Optima red top. Any help would be great. Thanks.
