Tripak evolution code 61

[Satch]

On my home time my fuel pump went out. After replacement and after breaking the power switch, i get code 61 battery low voltage. Yes it killed drained my new batteries with it trying to crank.

In the software, it's reading 12.4v. I've disconnected all batteries and tested individually. All were good, yes two had good but recharge.

Is the connector of the alternator supposed to have less than 5v?

I get 12 v to the alternator. Any help would be greatly appreciated. Have not seen blown Fuses. Checked Fuses at battery. Checked mega fuse, found a fuse next to alternator that was fine.

Resolved. Main alternator wire corroded internally. Had to run a new wire back.
