Direct grounded hot side on battery!
I installed an odyssey battery, got in a rush and didn't shim it up to have it tight enough with the hold down.
I was driving, hit some bumps, the hot lead direct grounded to the chassis through the battery hold down, mini arc welding it some. I installed the old battery and properly mounted it.
After this my abs lights are blinking, oil temp gauge is pegged, radio turns on and off, tach periodically jumps up and down
Is there a fusible link or an easy place to start checking? Any relays that'll go in this situation.
She's my daily driver and has been flawless.

If the hot lead of your battery shorted to ground, you are not likely to damage your fusible links/fuses. Although you could kill your battery.

If while trying to crank, those are signs of a weak/discharged battery.

Just had to be in a hurry!!
The bling of a sexy battery just got you all excited ?/
The positive terminal shorting to ground bypasses all your circuit protection I would look real careful at your ground cables and connections as well as your positive battery terminal.
Since it would only stop by the circuit being physically opened or the battery completely discharged very possible to have melted parts of the circuit beyond repair

Alright all fuses check out good. Tapped all the relays everything starts fine it is charging normal at idle.
I change the battery because I had a brand-new Optima sorry I put Odyssey earlier my brain was fried.
I put the old one back into eliminate the first variable, since it was fine I merely replaced it to have a brand-new battery in there.
It drives fine but as soon as you load the electrical system, like put on the headlights and then touch the brakes the tachometer jumps around, and the temperature gauge moves up and down with the turn signals.also the stereo turns on and off continuously kind of random. But it all seems directly related to load.
The voltage was stable through the battery at the connections while idling, 14.34 V at idle. I guess I will start at the ground cable and go from there, I also had the same stable voltage at the fuse block at the two high amperage leads coming off the battery into the fuse box itself.The way a
It acts it's like a grounding issue, like it is out of ground.

Yeah suspecting ground makes sense with above symptoms. Clean and secure connections? Electrically clean means shiny metal contacting shiny metal. Gray metal is not electrically clean. A terminal that looks clean outside may have been oxidized inside from shorting and age.

The obvious visible connections are good to go. I'm just gonna have to start tracing the ground cables and figure out if maybe one of them didn't arc or weld to something strange?

Also check cable insulation along entire length carefully for signs of speckling or melting. Can be a sign of havoc within.

I'm going to cut open the insulation tomorrow, the little wire loom so I can see inside where all the wires come out from the battery and go down under the motor.

I think you are right.....you have a ground issue....the ground that goes from the engine block to the chassis. Take note of where your battery ground cable goes. I bet it goes to the engine....close to the starter? The issue is the negative side...the positive is aok. So, they have to have a kind of "fusible link".....a #10 wire from block to sheet metal. That wire is probably fried.

I'll check for The block to chassis ground. I'm getting off work early today so I have some daylight to mess with this. Trying to sort issues after dark isn't too fun.
Is this " Zuk"The differential guru by chance???

ZUK is the winner on this one. Thank you sir!! It was the small 8-10 gauge wire behind the block, above the starter to the firewall. Fried in 2. Replaced it with a 6 gauge and also replaced my battery to chassis ground as well, it had been disconnected for years without issue.
All symptoms are gone!!! I can get the Z06 back in the garage and get back to breaking 200,000 on the 97.
Thanks for all the help oh here.

If I get things situated in the next 3 to 6 months, I may be visiting you for some regearing as well. I'm out in Tucson now.
