Transbrake Delay Box

[jspell]

Hey Dan,
Just installed a Dedenbear RTD-7 box and it makes the solenoid release appear "lazy"  once the entered delay time is reached?  With no delay the solenoid snaps in / out.

Something wrong there ! It should release just as quickly with or with out a delay .

I would check to see if the solenoid is getting warm and sticking during the delay time, cause a lazy release, with no delay, and an extended hold on the button should cause the same result. If this is the result, suspect the solenoid.

We used the delay box this past weekend for the first time during a time run...when I released the transbrake button the car left like it was in second gear...what is happening internally when the solenoid is lazy releasing?

The reverse clutch drags on release this will cause the lazy leave.

OK, makes sense...should I look for internal damage?  Because the car lost a tenth in the 60' (1.19) after 5 consecutive 1.09 passes prior to trying the delay box.  thanks Dan.

 Did you run it after the one box pass? If so what was the 60ft. If the 60ft went back to normal without the box, I would say the hit did no damage. It is possible it started to glaze the reverse clutches, but I'm not thinking one hit would have done that.

The pass after the lazy run resulted in a slow (slowest 60') car ever went....which was 1.19.  The weather was considerably better (693DA) which should have resulted in an even faster 60'.  Top speed seemed unaffected.

I would pull the trans down and look at it just to be safe. Also I would swap solenoids the check it on the box.

Thanks Dan.

Keep me up on your findings.
