This illustration:
is a lab scope capture of a fuel injector but the same in theory.
A. Shows the 12 volt supply voltage.
B. Shows the voltage being pulled low as the trans brake button is being applied.
C. Shows the release of the Trans brake button and the
inductive kick 60 VDC.
D. When the trans brake solenoid button is released , the magnetic field collapses, and this generates the
inductive kick
If inductive kick was an issue for you, and the box worked as they claim it does…..at the release of the transbrake button you would no longer have that spike above 12vdc when the solenoid is released,
I have tested my car a few times over the years and never seen a issue with inductive kick. I believe this is product nothing more than a clipping diode? but I have never seen the inside of one, so I have no idea? Maybe the experts can chime in and elaborate?
I was told years ago by one of the manufactures of throttle stop timers I believe Biondo? ( I use a Mega 400) that the Mega 400 has diode protection built in, as does the Dedenbear and some other manufactures (so I was told….. and by no means to be taken as a fact)
Anyway you can measure inductive kick with a lab scope, a good graphing multi-meter, even a Digital Volt Ohm Meter. Set the DVOM to volts DC on min –max screen to catch it. Connect the - lead to a known good ground and the + lead to anyplace you want to test for high voltage and hold and release the trans brake button and measure the results)
I remember years back someone talking about inductive kick interfering with things like your throttle stop timer.....I guess thats possible? I run a position sensor on my throttle stop to my RacePak datalog to monitor for anomalies in stop time and position. (Thanks to
H&C&G&G Racing for the help.)
Most of my issues to date are pilot error!
I’m writing a book on called “1001 Ways to lose” and am now working on chapter 239
