Be carefull of these, I had one short out to the case and melt the wire to the ignition side. Fortunately turning off the key cut off the power. The terminal shifted in the body and since the pass through for this lug was not isolated it grounded the wire to the case. I was able to cut the wire out of the harness and splice in a new one. The configuration is slightly different than the one shown. FBO assured me that his would not have the problem I had. The new regulator he sold me was exactly the same as the one that failed. This type regulator has a bare wire going from the circuit board to the ignition lug.



It appears the same thing happend to my car with the previous owner...he ended up grounding the alternator and all seems fine (1970 alternator). The reason I know is I just noticed the wire from IGN side is melted from the firewall bulkhead back to the ignition switch in the dash.

I dont want this to happen again with new motor so I need to ask...if I have petronix (electrical ingnition) in my car with correct alternator (remand with one field) what style voltage regulator can I use (old style..NOS, or new one specificaly for cars with electronic ignition)?
