99 SLE Electrical Problem
Howdy all, long time no post! But I have been a frequent visitor. Like some others, I am experiencing a voltage fluctuation. on my 99 SLE, 1290l00 miles. Just a quick explanation: The car used to start with just a flick of the ignition, no pedal or anything. Now it takes two cranks, about three seconds each, stumbling on the first and catching on the second. The voltage is above 14 most of the time, but drops periodically to 8, and the lights dim and blower motor slows down, then it recovers on its own after about 8 seconds. And while this was happening I noticed my antifreeze dropping. I had the UIM and LIM replaced after finding that the antifreeze was leaking into the intake. At the same time they replaced the MAF because it was sludged from antifreeze. I caught this early and there was none in the oil, But I changed it twice anyway. So, today I decided to replace the positive battery cable and when I took the bottom pan off I saw what I thought was the obvious answer to my problem. The cable was touching the exhaust manifold just above the starter and was melted and the cable was worn halfway through. An obvious short! I thought "great I will just replace it and that should take care of it". I replaced it, buttoned everything back up and it started just like it was new again! YAY! I took it for a drive and was in seventh heaven unitl it happened again! Voltage dropped to 8, then recovered. I drove it home, turned it off and tried to start it, and it was the two cranks for 3 or 4 seconds then stumbled and started. So I cleaned the negative connection at the battery, (very corroded) and took it for another drive, and it happened again. (oh,I also I had the fuel pump replaced because it was drawing 10 amps, and they did the fuel filter at the same time. This was one week after they did the UIM and LIM, and replaced the alternator for the same price as what I could get it for, no labor so why not?). Any ideas? I am going to relpace the negative cable in a couple of days to see if that helps. By the way, where does the negative cable attach to the engine? I fully trust my mechanic, but don't want to take it back to him and pay the diagnostic fee for this issue if I can help it. Any commens will be appreciated. Sorry for the long post!
