and when i turn on the headlights the car shuts off. but if its in park the car wont shut off. I had the alternator tested and it passed, and i put in a new voltage regulator but it still shuts off.you got a bad ground on it, i own a 71 340 car and have been through this with it a few times, once when we swapped engines out and forgot to put the ground wire back to the body on it,make sure the engine ground is good also,id say you,ll find it in the ground wire on this one,good luck.well id really have to say its either a short in the light switch or its not working at all and when you had this test was it on the car and running only right way of checking it drive to any shop and ask to have it check again and while your checking have them hit the lights like when you say it does this an dthey can see what happens on tester and if theres a draw they wil see it a but most likely since it only happen when you hit light thats where id look for shortThat aged vehicle probably needs the electrical charging system's circuit over hauled and that could be part of the problem you're having now.You'll need to check, for corrusion or rust and maybe clean the system with a small file, fine sandpaper , small wire brushes the battery, starter, alternator posts, connections and connectors, plus the engine block ground, clean or replace any and all ground wires,plus use new screws etc in connecting the grounds ,and create new ground wires or ground connections when their too rusty etc to remove.If you want to spend the time it's well worth it to take out the relays , and fuses with the battery disconnected and clean their connectors, especially any fuses etc located under the hood. Plus clean , re-gap or change the spark plugs , clean the connectors inside the spark plug wires with a flat head small screwdriver, just be careful not to scrape the wire itself inside the connectors and be sure to clean the ignition coil connectors too.Plus I highly recommend changing the gas filter especially if you've not been changing it on a yrly basis.
Don't even worry about any old grounds if you made up new ones as long as their not in the way and you've it done right.
Hope that helps and best of luck.By the way it might not be a bad idea to pick up a service manual for that vehicle. I'd highly suspect the problem is related to bad or corroded or rusty connections especially if the parts you've been replacing are battery's , starters and alternators etc.
After doing this work and if it stills does that for sure have the alternator retested and remember that not always if a alternator is faulty does a tester indicate so.#If you have any other info about this subject , Please add it free.# |
