I have a 2006 Precedent with factory lights, horn and dc/dc converter. My turn lights, horn and headlight causes a hum and they don't function. My taillights and brake lights work fine. Sometimes after a complete charge everything works fine, then quits after a short drive. I have reseated all connections on the dc/dc converter, behind the dash and checked the fuse at the dc/dc converter and 1 under the cover under the seat. I'm suspecting the dc/dc converter. Help!

P.S. I swapped the dc/dc converter between my other 2006 Precedent. No help--Thanks

We replace the stock voltage reducer with a heavy duty 48 volt to 12 volt unit and that corrects the problem.
The reason the tail and brake lights still work well is that they are LED's and take less current.
