Battery Stabiliser Question
Just went to fit a battery stabiliser to my 2008 Bullitt. Rather than install a socket and hard wire it to the battery, I decided to use a universal plug and charge the battery via the “Power Outlet” socket located in the dash. I have checked that the socket is live with the key off (it is).
Here’s the situation:
Voltage at the battery = 12.44 volts
Voltage at the dash socket = 12.40 volts
Voltage at the battery stabiliser = 16.33 volts
I have continuity between the stabiliser plug and the dash socket.
The voltage at the battery with the stabiliser connected and on, is unchanged at 12.44 volts.
I have used 3 of these stabilisers before (including this one) and all worked great; I just never checked the output before.
Is there something in the S197 that prevents back feeding? Am I missing something? I recall that this stabiliser is voltage sensitive, so maybe it's already sensed a fully charged battery so is "dormant"? Like many S197's, this car will go flat after 3 weeks of inactivity.
