Solar chargers are a bit useless in this country, what you need is a wind generator

I'm sure I read that bump starting is not good for modern engines because of all the hi techy stuff in them.

BTW, it's an ammeter, not a voltmeter that needs using to test if current is being drained
Thats if your testing the battery whilst it is still connected to the car electrics. My suggestion was to disconnect the + terminal and connect a voltmeter between the + terminal and the + battery post, that will show if there anything using juice when the ignition is off.
