AUX battery charging
Hello.
My G does not get to see much of roads
and to keep batter topped, I have hooked up to a tricle charger. Question is about AUX battery. Does that sit parallelto primary battery and also gets charged or I have to separately charge it from under passanger seat ?

Your auxiliary battery is charged by the alternator when the engine is running, but when parked and using a trickle charger on the main battery, it typically won't charge the aux battery unless they are physically linked (which they usually aren't when the car is off). You'll need to charge it separately under the passenger seat.
