Hello, I'm in the process of converting my 53 clipper to 12v and wanted to share my parts lists and info for anyone interested in doing the same conversion. I will continue to update this thread as I make progress.

Info


Lighting circuit

For the most part the lighting circuit is pretty self explanatory but I would like to explain a few things.

- Inside the instrument cluster are a total of nine bulbs. Eight of them are #57 bulbs while only one is a 1445 bulb. Four of the #57 bulbs illuminate the instrument cluster, two of them are for the direction indicators, one is for the battery discharge indicator and the last one is the oil pressure indicator. The one 1445 bulb is for the high beam indicator.

- The research that I did regarding the turn signal flasher indicated that some manufacturers 6v units did work on 12v while others didn't. I initially powered everything up with the factory unit and it was a no go. I guess the units Packard used doesn't like 12v. The 550 flasher relay was a direct replacement on my 26th series but may not be on an earlier model.


Misc

- Stock 6v horns and 6v horn relay work fine so far.

- Stock 6v blower motor also work fine so far.
