Alternator

Streamline the engine compartment in your street rod or muscle car by eliminating excess wires with this King Chrome 1-wire alternator. Based on the GM Delco-Remy 10SI alternators, these 100-amp units are perfect for vehicles with added electical accessories. King Chrome alternator housings are hand polished to a high luster prior to applying the show-quality triple chrome finish.

This one wire alternator simply needs hooked up direct to the main battery lead or power source. Then the internal regulator picks up the available current and kicks the alternator into the charge mode at the pre-set voltage.

  • Hand polished, triple chrome plated finish
  • Internally-regulated GM 10SI style "one-wire" alternator
  • Quick, easy hook-up with supplied instructions
  • Direct replacement for most 1971-86 GM cars and light trucks
  • 100 amp max output
  • Excellent idle output

 

Bracket

These steel Ford Y-Block car alternator brackets mount in the same location that the generator did, but allows you to run the common GM Delco style alternator. You should even be able to run the same belt length as the original.

Application

Works for most of the Y-block applications except for the 1955-57 T-Bird application.  It will not hold the alternator in the proper location for the belt alignment on the 1955-57 T-Bird application.

Applicable to most of the 1954-62 Car and 1954-64 Truck Y-blocks except the T-Bird as noted.

Overall Assessment

Customers widely regard the product for its aesthetic appeal and functionality. The ease of installation and the extra feature to connect the indicator lamp were special highlights. However, some customers noted the bracket for securing the alternator could be improved. Users particularly lauded the product's ability to allow seamless transition from a generator to an alternator with its simple and effective design. The product outperforms competitors, especially with its user-friendly qualities and superior material quality.

It's good looking and operates well. It was easy to install, and it had an added feature that allows hooking up the indicator lamp. The only issue is the way the bracket for holding the alternator tight in place, is awkward to deal with. I used an Allen head bolt so I could tighten it easier. since the bolt goes in through the back and underneath.
