I replaced the alternator on my 78 K10 truck, & now it melted a brown/white striped wire, blowing two fuses radio/TCS & instrument cluster feed. Traced & replaced the brown/white striped wire & it runs from the fuse box to the ignition starter switch on the steering column. Checked all effected wires and they are good.
Can the alternator regulator or ignition starter switch be bad?
What does (SXL) and (HXL) stand for I see this on some wires in the wire diagrams ?
