Electrical help. Herpderp
So I'll be honest, don't know that much about electrical issues.
Sometimes (~50-70%time; cold usually but not necessarily, started about a week ago, no changes) the car will have power; acc, radio, amplifier, etc. until I turn the key to start and as soon as the starter solenoid clicks the entire car goes dead (lost trip comp, odo, all electrical, etc.) and I have no power. I open the hood, wiggle the battery, interior lights come back on, car starts just fine and runs for-ev-vvvvvver. Not a loose connection AFAIK. I'll be checking grounds and relays tomorrow.
I know it's something simple like not having an LSx, using AMSoil, or being 4X4 status, but i'd rather get it taken care of before I drive to SC. Shine your light, fuckmooks. Or just fill this thread with catchphrases, whatever. BTW I do not use AMS oil. M1 Usually

Is this a '52 Chevy we are fucking with?
How about a Honda?
You have a bad/loose connection, I'm betting on the ground cable on your VW.
Has it caught fire yet? Why not? BMW?

Its a connection issue. Clean and seal the battery terminals first.

copy copy. but why only when the starter goes to pull current does it happen?
btw, i do not remember making this thread hahahah

The connection is there, but not good enough to support that kind of draw in current?
Complete guess here...I'm electrically retarded for the most part.

Where ever the weak link is its acting like a fuse. When the high current load is applied it heats the surface of the poor connection and when stuff changes temp it moves. Losing said connection.
GM side post setups are bad for this. they seem fine untill the starter hits. Go wiggle shit and its fine again.
Scrub the terminals with wire brush or one of those terminal cleaning cones.. grab some battery sealer and tighten shit back up.

i thought with electricity, a connection is a connection. then again, i know nothing about electrical.
problem is, why is it killing the entire car? there's some hokey fuse/relay looking thing on the positive cable.

^That's what I was getting at.
In a much more ignorant manner.

when the connection "opens" under high load, or a higher resistance the voltage drop across the connection drops considerably. Honda's are known for the frame to tranny ground strap rotting away with age, like 20 years old, to the point the ground becomes a huge resistor.
The current will then seek next least point of resistance, the valve cover to front core support ground. In some cases even melting it.

No the connection at the battery terminal actually isn't touching. Its clamped on but corrosion or a burnt surface is separating the two pieces.

I'd say use some sandpaper or steel wool to clean up the terminals and cables.
Maybe throw a corrosion resistant spray on it after you do that...?

not a bad idea at all.
on the plus side, my trip computer thinks the car is averaging 26mpg, which is fucking phenomenal
