With the above diagram, you can upgrade your charging system from the 30 to 46 amp alternator to a 60 amp alternator.
Also by adding the electronic voltage regulator, you get better charging & no danger of a voltage spike from the points style regulator damaging your electronic ignition e.c.u. If you have updated that system.
This is great for those of you whose stereos have large sub-woofers, 200 watt amps,& bass tubes (you know who you are). This upgrade will help you from frying your wiring harness.- Roger Kizer
