This is interesting. I wired in 2 gauges and tapped into a acc hot fuse (cant remember which one right now) as well as tapping in my rear fog light also from another hot acc fuse. After the instal I swapped out my stock battery for an odessy pc1200 which I had lying around for a bit. I use to put my battery tender jr on this odessy bat and it would show full charge imedently. Now that its in the car, which hasnt been driven in about a month (started up for a while but not long) when I hook the tender to it it takes overnight to show a green charged light. Pretty odd for an odessy to take this long.

Ive also got a diehard gp 35 laying around my garage and it shows full charge instantly same as my sportster and my riding mower
