So.... got it charged up enough to run around (hot wiring it to about 660 watts of solar panels for direct DC charging, under supervision (voltmeter every two or three hours) since there is no charge controller). The AC charger is dead. The batteries are not actually all that bad -- after a few mile drive, including about a mile long 5 to 10% grade -- maybe maxing out around 15% on a few short sections, they all bounced back to around 12.2, except for one at 11.8. I'm going to throw a 12 volt charger on that one to see if it'll come up. The one new battery was back at 12.65 afterwards. During driving, I did see up to 250 battery amps (on the highway, going about 55, slight downhill), but coming up the long hill, it dropped to less than 10mph, and battery amps would not go over 100 amps floored in 1st gear. I felt like it was going to stall out and stop, but it never did. Motor was hot to the touch (could touch it, but not keep your hand on it) at the top of the hill, but the controller was not hot. I did wait about 5 minutes before feeling them, so maybe the controller had a chance to cool off. Voltage sagged to about 60 volts under the load of climbing the hill. So, yeah... needs a higher power controller, motor, and batteries :)
I did get two offers to buy it in that short drive. Old restored bug has appeal :) On Thu, May 23, 2013 at 9:50 PM, Zeke Yewdall <[email protected]> wrote: > The first step now that its at my house is actually to figure out what is > wrong with the charger -- it's not charging the batteries at all.
