battery wont hold or isnt getting a charge on 72 cl350

[bornugly]

hey i have a 72 cl350 and im having some trouble with the charging system, ill charge the battery over night and the ride around for an hour or so and by the time i get home the battery is dead, but the bike will run. it will also kick start with a dead battery and run, but poorly (especially with a headlight on). i know the charging systems in these bikes have never been very good but i was wondering if anyone has put a permenant magnetic alternator or something of the sort in there to maybe run with no battery or just be charging all the time. ive replaced the rectifier already, no change. electrical work is not my strong point. any help would be appreciated.

Have you put a volt meter on the battery as the bike is running to see if its charging or not?
Could be a
- Bad battery, not holding a charge
- bad regulator not pushing enough current into the battery
- bad recrifier, not coverting AC into DC
- bad stator, not pumping out enough voltage...

you'll have to test for each of these... the cb350's have a weak charging system to begin with...

It could be a bad ground somewhere, but is more than likely a bad rectifier. You can buy them or make them from kits at radioshack. Or if you'd like no battery, its going to cost you about $700 for a Magneto ignition by Todd Henning, but I'd hope you'd be making a race bike

It already has a permanent magnet system.
Take battery to Pep-Boys (or wherever) and have them load test it.
There really isn't anything 'wrong' with electrical system, except its at least 37 yrs old.
Did you change regulator?
