I've got a problem with my gauges. I just got the car back together after having a new transmission pump installed and getting the converter fixed by yank. The car has a battery relocation kit so the battery is in the trunk. This is a pull from stop light to about 40-45mph (GPS because as you'll see my speedo doesn't read correctly.) And only a maybe 1/4 throttle. I wish I had enough power to do what it does.

The car is a 98 LS1 that has a cam and a 4l65E built by ACE racing out of Texas and 3.42 gears.

The voltage gauge as you can see reads really low. I pulled the negative cable off of at the battery to see if they car would stay running and it died the second I pulled the cable off. So I'm assuming I need a new alternator. But do you guys think that my alternator problem would cause the gauge to do what they are?





I have no codes what so ever as if I missed a plug or anything.

Any thoughts on what it could be?

Thanks for any input!

Lets hope you didn't burn up any electronics by pulling the battery cable. You never should do that on a modern car. Get a voltmeter and learn how to use it. By the way an unloaded alternator can put out over 100 volts.

Start w/ checking all the grounds. And, what Pacer said^^^^^^^
W/ the trans having been taken out, I'd look at the grnds at the rear of the head.

I couldn't find my multimeter and I was in a hurry to try and see if I could narrow down my problem. Everything is working the same as it was before so I don't think anything fried. I didn't unbolt any grounds either. All I unplugged was the 3 plugs and the vacuum line to the trans. And then the o2 sensor to get them out of the way.
