Fade FX Posted July 22, 2015 Report Share Posted July 22, 2015 Is there a kit for adding a starter motor and alternator? Is It advisable to change to 12v from 6v? Where do I order this kit? Thanks! Quote Link to comment Share on other sites More sharing options...
Fade FX Posted July 22, 2015 Author Report Share Posted July 22, 2015 Any advice on adding a starter motor and alternator to my b1b? I also want to change to 12v. Any advice would be great! Quote Link to comment Share on other sites More sharing options...
pflaming Posted July 22, 2015 Report Share Posted July 22, 2015 It is difficult to understand your question because the starter mounts directly into the engine. The alternator can be mounted by usung a redibolt / all thread bolt and then secure and center it with the nuts. If you. Are going 12 volts, nothing needs to be changed on the starter, it should never run long enough for it to be damaged, provided the engine is properly tune. My engine starts on the 2nd revolution which means it starts in less than a second after it is engaged. 12 volt vs 6 volt is personal choice unless one wants to add a modern radio and other such items which require 12 volts. I changed to 12 volts for that reason only. Quote Link to comment Share on other sites More sharing options...
MBF Posted July 22, 2015 Report Share Posted July 22, 2015 Starter should be ok as long as its used in short bursts. An internally regulated GM alternator simplifies the installation and eliminates the firewall mounted regulator. You'll need to fabricate a bracket for the alternator (numerous examples are shown on this forum). Make sure that the alternator pulley width matches your crank and water pump pulleys if possible. You'll have to change from + ground to negative, switch the wires on the back of the ammeter and on the coil. In addition to replacing any bulbs (head, tail, dash, cab, etc) you'll need a resistor for the fuel guage. A 12V coil, or a ballast resistor will need to be installed to protect the coil if you're not updating it. If you have a heater, a ballast resistor will also need to be installed on the fan motor circuit. If you've got electric wipers, some type of step down resistor will be needed there too. Advantages: better lighting, quicker cranking, and ability to use modern accessories. You can also get by with lighter gauge battery cables as the amperage will be half of what the 6 volt system.
