Ovation Cigarette Lighter Adapter

[Healthpilot]

I connected the Battery Minder cigarette lighter adapter to the cigarette lighter plug in the cockpit and now the USB adapter (tried 3 different ones) is not working. Is there a circuit breaker that I don't see on the panel for this one?

Fuse?

Mine also has an inline fuse and a circuit breaker.    Trace the wire and you will see it if yours has it too.

Is this how you plan to keep your battery topped off?  It would certainly eliminate all the wiring that many install back to the avionics bay.

Installing the cables for the batteries is about as easy as it gets. 
you can run the dongles to the tks door, or the hat rack with a grommet. 
the parts usually come with the chargers and takes less than two hours to install everything.  
the gauge of wire to the cigarette lighter is pretty small, I would be very suspect of the efficacy of that method, or the safety.

Well, a dedicated line to the battery or batteries would be best, but I would have guessed that the wiring to the cigar lighter would be fairly robust.  But, I have never paid attention to it before.

Your batteries are directly beneath the hatrack and very easily accessible. 
get a stool and prepare to contort and scrape some knuckle but it’s very straightforward. The charger lines come with an inline fuse and both ends are finished to fit battery lugs and charger cord. 
the battery minder seems to work well for me.

The cigarette lighter socket in your plane (SN 29-0464) is connected with a 16GA wire to a voltage converter (output voltage 13.7-13.9VDC 5A) mounted on the tailcone bulkhead.  The 5A inline fuse for the converter is attached to battery relay 2. It should have a label (if it hasn't fallen off) that says VOLT CONV or something like that. If the fuse isn't blown then the converter is probably fried. The good news is they can be found online for cheap, even on eBay. Search for Transelectric SM2412-5. I think these things were used on golf carts.

As stated before your cigarette lighter may be 12V, you have two 24V batteries, not sure if you can backfeed though the step down transformer, standard solution is an Anderson connector on each battery, if no tks door, Anderson connectors are typically mounted on hat rack or on left cabin panel in luggage compartment, think battery minder sells Anderson connector kit with fuse

The cigarette lighter sock has a label 12V or 24V

Thank you, Dave I will check, and report back.

I was not planning to charge the battery this way but rather just update G1000 databases and learn buttonology without depleting batteries.
