    slugish starting

    Even though I have a trickle charger on my dual battery 70 911; leaving it for a couple of weeks, come in and start it with a slow a sluggish starter motor. Once it is running; the car starts fine. It seems my charger is not up to the job. My SWB with the trickle charger starts up nice and fast. So I do not know if it is the battery or the charger? Chris

    Try an Optima battery. My car starts like it's on steroids now.

    Since the charger keeps your SWB battery up it is not the charger. You either have weak batteries or a weak starter. Have your batteries load tested. Of course this all assumes that there are no wiring or connection problems.

    Yes it could be connection problems as I am 2miles from the beach. But I will look at the starter as I think it is original from 1970. thanks Chris

    Possibly a weak contact in the ignition switch. I'd start with the starter and battery but don't forget the switch if those don't work.
