Nitrous, line-lock, trans-brake and other solenoid usage warning:
LPE has found that these solenoids can cause fly-back voltage levels at times in excess of 600 volts.
These voltage levels have the potential to damage sensitive electronics including the LNC-003, the
PCM/ECM and other modules in the vehicle. Lingenfelter Performance Engineering has developed
a transient voltage suppression (TVS) diode kit (PN L450080000) for use with line-lock solenoids,
trans-brake solenoids and other aftermarket automotive solenoids of this type. LPE recommends the use
of our noise suppression diode on all vehicles that have a line lock or trans-brake. This kit comes with
one TVS diode. If you have a vehicle with multiple solenoids we recommend obtaining additional TVS
diodes for those solenoids.
Solenoid
Install the TVS diode across the solenoid wires
as close to the solenoid as possible. Polarity does
not matter (Red and Black wires can go to either
solenoid wire). If there is no accessible ground
terminal to connect the diode to, such as the case
with a trans-brake solenoid, the diode should be
connected to the nearest ground source. In the
case of the diode for the trans-brake solenoid, the
diode should be connected to the transmission
case as it will provide a ground path.
LPE recommends using TVS diodes on:
• Nitrous solenoids
• Nitrous purge solenoids
• Fuel solenoids
• Line-lock solenoids
• Trans-brake solenoids
