Batboard

So um yeah...

Bought a TLN5277B Negative Ground /\/\ Power Line Filter off of eBay...

Picture clearly indicates "NEGATIVE GROUND" on the item for sale...

Well... I received it today, except its a TLN5278B, and reads "POSITIVE GROUND"...

Before I send off a nastygram to the seller...

Is there any easy way to use this positive ground filter for my negative ground application?

Here's the pic of the item that was sold... Mine is the same except part number and the "TO BATTERY POSITIVE TERMINAL" actually says "TO BATTERY NEGATIVE TERMINAL"...


HELP!!!

If you can get inside the box, you can reverse the big capacitor so the + side is to the coil/choke. Negitive lead going to the ground lead. Then wire it in with the battery lead going to positive battery.

There maybe more than one polarized capacitor in there. It has been a while since I have seen one.

I opened it up this evening and did find a single polarized capacitor in the device. It's doable, however, the leads were fed through and crimped on to the studs of the PCB holding the diode array, so a successful desoldering attempt without causing damage is unlikely per the wife (who teaches the certification class on through hole, surface mount and wave soldering at a local custom electronics manufacturer)... No easy way to get around it...

The flux residue present is horrible compared to modern standards... Oh well..

I did shoot off an email to the original seller to see if they had the correct one in which I could exchange... Oh well..

On a side note, what sort of connector do I use to connect off of the "To Radio" stud on the right side of the device? It almost looks like the same type of male connector from a high power Spectra power cable.

Thanks!
