Guest gloria morris Posted January 9, 2013 Share Posted January 9, 2013 When the 68 skylark 350-4bb is at normal temp. and you turn it off. If you don't give it 15 minutes to cool down, the starter turn very slow. Always kicks over. Timing is right on, and there is a shield between motor and starter. Any ideas, Thinking of rerunning the wiring to keep away from the heat Link to comment Share on other sites More sharing options...
JZRIV Posted January 9, 2013 Share Posted January 9, 2013 Those symptoms are usually the result of the stator windings inside the starter motor going bad. The heat amplifies the problem. Assuming all the battery cables and connections are in good shape, the starter probably needs rebuilt. I would have the existing one rebuilt vs buying an over the counter one from places like Adavnce, autozone, Pep Boys etc because they are remanufactured in China and quality is garbage. If you do want to buy an over the counter starter instead of rebuilding what you have go to NAPA. Link to comment Share on other sites More sharing options...
Guest gloria morris Posted January 9, 2013 Share Posted January 9, 2013 The starter is new from auto zone. Thanks Jason I believe you are right, that was on my mine when i got it. There is a place here in Hagerstown that rebuilds, that my be my next stop. First I will go over the ground again. Anyone else think of something please let me know.

JohnD1956 Posted January 9, 2013 Share Posted January 9, 2013 I would agree with Jason. And I would also evaluate the positive battery cable when I removed the starter. If it appears to be original, or a decade old or more, then I might suggest changing it before re installing the starter. Link to comment Share on other sites More sharing options...
Guest gloria morris Posted January 9, 2013 Share Posted January 9, 2013 Thinks guys, I will give everything a good going over. Plus replace both cables with heavy ones Link to comment Share on other sites More sharing options...
JohnD1956 Posted January 10, 2013 Share Posted January 10, 2013 Well, if you are just looking for things to check, the rebuilder will probably check your starter and solenoid for you. You may want to charge up the battery and take that to your local parts store and ask them to do a load test on it. If that's okay then there really is nothing else to check. If not then you may want to take the alternator and regulator for a test, but honestly that is going overboard. As is putting on heavy guage wires. One thing you will find is that the positive cable makes a very odd twist down in front of the starter. Failure to recreate this twist can result in the cable riding against the exhaust manifold or cracking the front of the solenoid. The standard size cable will work just fine. Probably has been working for close to 40 years now, and there is no reason ( in my opinion) to over engineer a sucessful set up. And if you check places like Year One on the internet, chances are you can get cables that are reproductions and exact fit including this odd twist. The only other thing I will mention is cleaning the terminals where ever you take them apart. I mean lightly sanding the surfaces with very fine sand paper so you get a good connection. I also recommend using a product called oxy-guard, which I got at my local Ace Hardware store in the electrical aisle. This is a grease that helps slow down any oxidation resulting from mating two different metals. It can be use on all electrical connections and besides providing a bit of lubrication it does help to seal comnnections from moisture and keep them clean after you have done all that work to clean them. I also use it on my battery terminals . Great stuff... Link to comment Share on other sites More sharing options...
Guest gloria morris Posted January 10, 2013 Share Posted January 10, 2013 Thanks again. I'll start with the starter. Have them rebuit or buy one from them. Will replace pos. cable and go over ground. Battery is new, replaced last march was 9 yrs old. Son still using in his truck. I use oxy-guard is good stuff. Will check wires from solenid back, or just replace. I know it is something simple I've missed, but you guy have got me in the right direction. I'll get her. Got 2 months till the Myrtle beach car show, 3/14-3/16,. Put on by PEE DEE Streetrodders.com. Great show all money goes to chidren charities. This will be our 12th yr. drive the Buick down. Always look forward to Mar. Link to comment Share on other sites More sharing options...

Always look forward to Mar.Electrical problems can be tough to diagnose especially on an internet forum but I would agree starting with starter now that its from AutoZone . Typically a bad cable will reveal itself whether cold or hot so I would leave that to last if visual inspection shows they are OK. A competant rebuild shop can test the starter windings to confirm problem prior to rebuild. They check the stator windings with a special tester that checks for any leakage to ground or in other words a short circuit from insulation breakdown.A close friend couldn't resist buying a starter from Advance vs NAPA for his Ford truck because of a few dollars difference in price and Advance was more convenient 5 miles closer to home. This was after I pleaded with him to NOT do it! He said but they have a warranty! The following is no exxageration and 100% honest truth. He proceeded to return 3 defective starters before he finally went to NAPA. Unfortunately to get his money back instead of a another junk starter, he had to return the defective one to Advance but then he had already turned in his $30 valued old core to advance so now he was out $30 because he had no core walking into NAPA. So much for convenience and warranty.I know its going the way of the dinosaur because of cost but when it comes to starter and alternator rebuilds especially for older stuff, I prefer to deal with the person face to face who is rebuilding it and that means taking it to a local rebuild specialist.

ol' yeller Posted January 10, 2013 Share Posted January 10, 2013 I am not as familiar with '68s as I am with '64-5. They (64-65) all had from the factory a ground strap from the back of the head on the right (passenger) side to the firewall near the heater blower. These straps dissappear over time. Reassembly of engines and restorations that include repainting of engine parts, makes the natural ground through the engine block not optimal for heavy current draws. This may not be your problem but If you are supposed to have this strap and it's missing, I'd replace it. Link to comment Share on other sites More sharing options...
