63 honda 305, low and terrible voltage
63 honda 305, low and terrible voltageGetting 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. 66 dream, 78 cb750k, 02fz1, 09 wing
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. Davo
Re: 63 honda 305, low and terrible voltageYour 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.
