I have a Honda crank pulley for the B16 CTR motor that I would like to put on my B18C1. This pulley only drives the alternator and I have already removed my PS and AC. The new pulley is slightly smaller than the OEM one so I cannot use the 310 belt on there now and need either a 290 or 295.

What I would like to know is if there will be any effect on the electrical system of my car by running the alternator with a smaller pulley?

Thanks
