I have an LK-530 and an LK-7900, and I'm not sure the LK-530 is working correctly.
As of now I am just using the cigarette lighter on my car to power the 530 and the 7900, but will eventually get it hardwired.
My issue is this: The LK-530 only charges and draws vehicle power when the engine is running. When the engine is not running (even if the key is set to ON with all electronics powered including the cigarette lighter, or obviously if everything is off and key removed), power is only drawn from the LK-530 battery pack. I would have expected the LK-530 to draw from the car battery (if the cigarette lighter is providing power, even with engine off) until the car battery was below the cutoff, then switch to the internal LK-530 battery. This is not happening.
I don't have a multimeter, so I don't know the voltage coming out of the cigarette lighter, but the car battery is relatively new and I don't think there are any problems with the car battery itself.
My questions would be:
1) is it normal for the LK-530 to immediately switch to internal battery power when the engine is not running but the cigarette lighter is powered? (perhaps due to cigarette lighter voltage being below the cut-off threshold when engine is not running)
2) If so, would hard-wiring the LK-530 to a constant powered (ie non-switched) location on the car fusebox provide more voltage to the LK-530 with engine off (vs using cigarette lighter)?
My original intent was for the LK-530 to draw from the car battery even with engine off until the cut-off voltage was breached, then switch to LK-530 internal power.
Any insight would be greatly appreciated.
