engine dying, lights coming on, s176 wire VERY HOT

Postby p1bump » Thu Aug 26, 2010 4:20 pm

hey guys n' gals, like the post states, the car has been dying. usually when sitting in idle or coming to a stop, it's warmer out and thus the A/C is on. I've also noted today that the 2nd wire from the inboard side is extremely hot and the jacket is a bit darkened/marred/burned appearing. It's hotter than the rest to the touch.

fyi, i just changed the serpentine belt, it was squeaking and a little glazed, I thought maybe it was slipping but it made no difference. the battery has been tested and checks out OK for now. the alternator was tested a while back and was reported to not be putting out the correct amperage. I took it home, tightened up the cables at the battery, the positive connected was not quite snug at that time. the problem went away for a few weeks, but I had not had the alternator tested again since. when the problem returned last week I snugged cables up again. now it's back for a third time and I know not what to do. :(

what in the hell could be causing this? there are no trouble codes except low voltage codes from various systems throughout the vehicle according to VagCom...

your help would be appreciated.

Those just have a random problem with melting. Replace the box.

that doesn't help much as nothing has melted at this point. I would like to keep it from getting hot and melting the box so as to prevent having to buy a box in the first place. Mine box is in perfect condition for the moment, but is the s176 cable continues to be so hot it will melt for sure..

Whatin the world is causing this?

my black "alternator cable"-s177 is just fine... Its the red one next to it that is hot, I'm going on the assumption that if I can remedy that problem it is quite likely the enginge sutdown & CEL's will cease.

any help on what is going on and how I can prevent a meltdown?

unfortunately, it's not my alternator cable nor it's connection at the fuse box that is seeming to get meltably hot at this time. that is what is the difference between my problem and others.

so what say I replace the alternator cable, which appears to be working fine and is not getting hot, what is to keep the other wire/terminal that appears corroded/burnt and get's hot now from continuing to get hot, corrode and burn/melt in the future?

Fixed your pictures for you, though I don't know what to tell you. How much would it cost to replace the cable? The fuses look fine, the wire itself being burnt like that could be causing the problem. Have you replaced that fuse recently?

thanks for fixing the photos, awesome!

no fuses have been replaced to date as faras I am aware, we've had the car since 22k, she's got 81k now....

well, disregard anything I said up to this point.... installed the innovative wiring cables and so far so good... but the weather turned cool the day I installed this package. so, we'll have to wait till spring/summer or a drive to phoenix to see if thing are working correctly for good.

nice cable setup that guy makes....

though I did forget to mention that I bent/twisted some of the smaller fuses on the battery top box when removing and reinstalling... ;(
