You may experience engine run on. This is caused when the alternator back
feeds voltage down the
#914
wire after the key has been turned off. This allows the
ignition system to still function causing the engine to continue running even though the
key is turned off or even removed from the ignition. If this should happen unplug the
alternator connector to shut the engine off. If you experience this, a remedy has been
provided.
As shown in the photo on the previous page and diagram below, a diode, splices
and heat shrink have been provided. If engine run on occurs, simply install the diode as
shown. When the diode is installed inline of the
#914
wire with the stripe towards the
alternator, the diode will let voltage flow towards the alternator, but not away from the
alternator towards the ignition system, thus fixing the back feed/ run on issue.
General Motors CS-130 Series Alternators
The CS-130, CS-121 and CS-144 alternators closely resemble the SI series
alternators. They will have an external fan behind the pulley and they generally have
some plastic casing on the side and back. These alternators have a four pin sealed
connector, seen in the photo below and in the middle image above. The regulator will be
marked P,L,S,F. This type of alternator was used on GM TPI and LT1 fuel injected
engines among other late 1980’s to mid 1990’s GM vehicles.
The two remaining wires, a 14 gauge black/red wire printed
#995 REGULATOR
BATTERY POWER
and a 16 gauge black/brown wire labeled
#914 ALTERNATOR
EXCITER
, will connect to the regulator on the back of the alternator.
