How do you test the 4500RPM module?
Not sure if it works or not. Saw it flicker once when I first got her, but haven't seen it since. I know I'm pulling some RPM's on these mountain passes. Don't want to blow her up.

Jim if you don't get a flicker at start could it also just be a bad bulb?

No flicker on start up. I know the bulb is good. I'll check the connections from there to the box. Truck runs fine. What I'm afraid of is if it's not working but allows the truck to run it might go "more bad" and cause a break down (in the middle of nowhere).
Those things are pricey, but I don't want to get stranded either.

Yes, bulbs can go bad and connections can corrode.
You can take the module board out and look for any damage.
I have mine removed since I have EFI and can set rpm limits in stages now.
The module will ground out the ignition voltage as well as illuminate the warning light, the faster you try to go the less voltage to the coil when it works right.
