Getting ready to tackle my electrical issues and wanted some input first.
I found my battery dead one afternoon, after a full hour charge we were back up to 11.56v off, 11.07v running w/o the headlight and 10.55v w/. Got a nice ride in a parked it like I normally do. I should note, I run with the headlight off because I have the original rectifier.
A few days later, I had a dead battery again. Charged again, this time 11.50v off, but when I turned the key my voltage dropped to a measly 6.something. Damn.
Would start with a jumper box, but would die as soon as I removed it.
Cheapo walmart battery, that had been working for a few months with no issues.
All grounds are tight and clean.
I don't know where to start.
My electrical know how is pathetic; besides checking for loose wires, I'm never certain which direction to go. I'm contemplating rewiring the beast, but hopefully there's some glaringly obvious issue at hand here in which a more experienced dreamer could easily point out for me.
thanks.

Start with a battery you can charge to 12.5 + volts before blaming the bike, then take it from there.
You may have charging issues, or it may just be a bad battery. You should be able to get 13+ volts while running at mid rpms, but that is starting with a good charged up battery.

Bloodwiser,
Charge the battery, leave the cables unhooked from the bike, and see if it still dies in a couple days. Either that, or take it to someone that can load test it for you. Buy a good battery, not a cheapo Wallymart battery!
Replace the old rectifier with a solid state unit.
You can run with the headlight switch on, but the bar switch in the middle, so you get extra voltage to the battery.

Your battery is Shot!
Get a new one and connect the Positive Wires/cable then (with the key OFF) contact the frame and the Negative side of the New Battery with a voltage meter.
You should not read voltage.
If ya do ya have a wiring problem. .......lm

A battery that is filled and charged need to be maintained. Our Battery suppliers rotate stock on prefilled charged batteries on a regular basis to ensure a fresh battery. A dry battery that you fill and slow charge yourself if the best alternative. Your WM battery spent most of it's usable life on the store shelf.
