Or you could just install 2 batteries. > I've heard of a setup which (on the flick of a switch) uses a lantern 12V dry battery to run your ignition while either your almost dead car battery slowly cranks the engine (without pulling the volts to the ignition so low that the car would never start anyway) or (if things are really bad) you push the car. The concept of using a dry cell to recharge your car battery enough is extremely hopeful, as a starter motor can draw up to 100 Amps (so that gives you about 1/4 turn rotation of the motor before you've exhausted your amp-hours). -- | /~~~~\ Bruce Paterson VK3TJN Company: Email Electonics | | / | Electronics Engineer ACSnet: bmp@cow.ecs.oz | | /-----/ /~~~~\ / / /~~~~~ /~~~~~/ bmp@ecs.oz | | / | / / / / /-----/ UUCP: ...seismo!munnari! | |/_____/ / /_____/ /_____ /_____ bmp@cow.ecs.oz |
