Hey fellas, I'm almost ready to fire my LS swap, I've noticed my battery keeps draining while the car sits, and today I was hooking up my standalone gauges and I noticed that once I hook up the sending wire on my oil pressure and my water temp the gauges spike all the way up, I've noticed while working on the car I seem to feel electricity transfer to me when I pressed hard against anything metal. What's the deal here? The pcm is currently not in the car, I'm using a Current Performance fuse block

Another thing, I can crank the car, turns over nice but dies out fast, like 5 seconds or so

Are you sure that VATS was tuned out of the PCM program?

By "dies out fast" do you mean the starter cranks fast and then slows down, or it starts and dies? If it startd and dies, then like the other poster said, make sure VATS is turned off. If it cranks slow after 5 seconds, then it sounds like your battery may be bad. Might want to get it tested.

I'm not trying to start the car, I'm trying to figure out why there seems to be a power drain and my gauges are spiked all the way

Yes the starter slows down bad and then clicks, if you read my 1st post in its entirety you'll read that the pcm isn't in the car, I get it back from Frost tomorrow, I'm just trying to figure out why the battery power keeps draining off after I charge it, if the battery was shot could it cause standalone gauges to peg out? Almost like reverse polarity?

Sounds like you have a short in a wire somewhere, killing the battery.

most likely you have some electrical device that is bad (switch, connector, key, etc).. do a google search for "how to find parasitic battery loss" to find out the steps to test and find what is causing the drainage.

Here are a few to get you started..

Hopefully your problem will be a simple fix. Good Luck.

So your gauges move when you just hook up the sender wires? They shouldn't move at all until he ignition power it turned on. Are you sure they're wired right? Also could be a bad ground issue. Bad grounds do all sorts of weird things, something to check.

If you are getting voltage thru your body, there is something hooked up wrong.[Or, not at all, such as batt ground.]
Look at ALL the power, batt connections.
U have GOOD grounds from batt to body, frame, and engine?

+1 for checking grounds. They do weird ****

Late update, ended up being a bad ground to the body, wish I would've noticed sooner, fried my oil pressure gauge

These things almost always seem to be ground problems. Glad you got it figured out, sorry about the gauge, but look on the bright side, bad wiring has been known to burn out whole cars, so a gauge is a small price to pay.
