yesterday i drove home made contact off engine dont stops

engine keep running like the ignition is on
the contackt switch is ok
at the 60 amps alternator below the cover the thin wire 568 had a bad isolation at the soldering

a inner wire was to the load cable so the wire no 568 give power to the wireno 12 ignition engine keeps running

a new wire at the alternator problem solved

this can happen george
