Dear, the parts I just sold paid for that part ;) Group: Members Posts: 1,568 Joined: 26-December 02 From: Williamsburg, VA Member No.: 16 |
Finally got my air filters..Freak'n two weeks due to a mix up (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif)
I drove the SIX around for about 20 mins and pulled in to a gas station for a fill up (1st one in a year). Went to leave and it cranked VERY slow and wouldn't start. So I sat there for a about 5 mins and tried to start it again. It cranked alittle faster, just enough to start. Drove home with no issues I get home and check the voltage at the battery 13.4v (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif) Nice. I shut the car off and tried to start it again...it cranked VERY slow. I came back outside after about 30mins and it cranked like a son-of-bitch and fired right up (IMG:http://www.914world.com/bbs2/html/emoticons/aktion035.gif) The battery is new..last year. The alt light is only on when I first start the car. Once I rev it above 1500rpm's it goes out and stays off. 13+ volts at the posts Any thoughts |

wrap it in a heat isolating blanket..... im guessing heat soak.

Sounds like the hot start problem. As the car warms up the engine is harder to crank over. Happened with my car. It has a 3.2 in it. I got one of them new high torque starters and the problem went away. |

Also, clean up all the connections in the starter circuit. The battery terminals, the terminals on the starter, the transmission ground strap, the chassis-to-battery ground strap.... Most contamination (dirt) offers more resistance when the parts are warm.

Starter motors require more amperage to produce the same torque as their temperature rises. Could be the starter getting weak, battery getting weak (voltage output is not the last word on battery condition), or bad connections as Dave mentioned. I'd eliminate the possibilities in order of cost...check connections...get an amperage draw test on the battery, then ckeck the starter motor if all else is OK.

Just to summarize what others have said:
The battery voltage doesn't tell you much in this case. What matters is how many amps are running through the starter. The main way to reduce the current (amps) is to add resistance to the circuit, and several things can do this. Any place where contacts are dirty or corroded (battery terminal, ground strap from tranny to chassis, contacts on starter, etc.), any place where the wire is too long or too thin (the way the car was designed in the first place; this is why many people add a hot start relay), or any place where wire gets hot (like the coils of wire inside the starter. So anything that eliminates this unwanted resistance will help. Ultimately, the coils inside the starter need to be replaced, which basically means buying a new starter. It sounds a little strange to me that your starter cranks, but slowly. My case, and most of the "hot start" cases I've read about have a different symptom : the starter doesn't turn at all until car cools down enough, and then cranks just fine. Maybe you are right on the edge, or maybe its more of a problem internal to the starter, as opposed to the external stuff like contacts. Anyways, cheer up. Cooler weather is coming..... |

(IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif) The type IV never had any problem like this. Guess the SIX is putting out more heat.......and HP (IMG:http://www.914world.com/bbs2/html/emoticons/drooley.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/driving.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/driving.gif)
Thanks, I added a relay and took her for a good drive..to sears and back (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) Didn't seem to have any issues. I will take her for another ride later with some traffic to see if that changes things. Thanks again |
