Changes, Cautions, Corrections
- SERVICE PRECAUTIONS - When replacing regulator, and during bench testing, be careful not to exchange the wire to plug "15" with wire to plug "67" (see illustration). Current passing through contacts would be high enough to melt second stage contacts before fuse in lead "15" would blow.
- HANDLING - During installation, removal, and handling, protect regulator from blows which might damage the resistors and upset adjustments.
- GROUNDING - During checks on vehicle and on bench, see that regulator is well grounded. If grounding is poor or open, alternator voltage will rise to an abnormally high value, which may damage battery and electrical equipment.
- CAPACITORS - NEVER install radio noise suppressor on regulator plug "67" as operation of contacts will be adversely affected.
- COVER GASKET - Should gasket require replacement, use only a gasket of same original material. Unsuitable gasket could release harmful volatile substances into regulator which will foul contacts.
- SUPPLY CIRCUITS - DO NOT connect electrical accessories directly in circuit between alternator and voltage regulator (i.e., cable between terminal "30" of alternator ignition switch, plug "15" of regulator, or cable between ignition switch and voltage regulator), since alternator voltage would rise and affect life of battery and electrical equipment.
