Title says it all. Did the search here and the interwebs. Trying to find a replacement 50 ohm resistor. The old 12si alt used that and the paperwork I dug up for a serpentine conversion calls for 50 ohm with the CS130. Although I've seen 85 ohm mentioned elsewhere. I would like to know what wattage is appropriate as well.
 
Are you talking about making a 12si into a self-exciting 1-wire alternator? If so, I always used a small diode rather than a resistor.
 
I'm not converting an alternator. I'm rewiring an engine with a CS130 that had a 12si before.

And I don't want to run a light bulb. Just need to find a new resistor.
 
Up to 300 ohms +/- from what I remember. 2 watts for 100 ohms, 1 watt for 200 ohms, 1/2 watt for 300 ohms... if I got my math right.

I might have an extra if you PM your address.
 
X2 the above is what I used on my cs144 install for the excitor. Haven't had any problems since installing it about 2 years ago. My harness had an excitor wire but the first alternator lived just long enough to get me far from home and crapped out so I soldered this in. I found it at radio shack for two dollars or something
 
Radio shack! Do they still actually still sell electronic componants? ;)
 
Follow up. My local Radio Shack came through.:clap:

Thanks for the help:beer:
