Hi Forum - I have a 2000 2.7 and am having the usual electrical problems. I have a charger coming on for an hour every day to keep the battery topped up so the alarm doesn't go off. Someone told me the trouble is that the alarm battery located under the passenger seat needs to be replaced. I think the seat needs to come out, but does this battery need changing regularly, and does it receive a charge from the main battery or the alternator? It's a new main battery but if the charge is taken from the alternator only it would mean the car is not being driven enough. Is it a simple job to replace the alarm battery, and is it the same as the main battery that by turning the key to the first position it stops the alarm going off while making the switch? Thanks, Barry.
