I'd need a picture and more details on a "5 wire standard RR".

If it is an aftermarket fullwave RR, then you've got to float/isolate the stator ground so the RR will work. You battery minus is required to be grounded for the starter motor to work, so you must isolate the stator lighting output in order to use a fullwave RR.

The stock stator is grounded because the stock RR construction allows this to work with a grounded battery. As soon as you deviate from the stock estart RR, the sytem also has to change. Now your lighting grounds must be lifted from the chassis ground and connected to the new isolated stator ground (which is no longer connected to engine/chassis ground). The isolated stator ground is no longer a ground, it is simply the "other side of the circuit".

The easier way is to buy an estart harness and stock RR.
